Blackstar Amplification HT-Dual
BLackstar has been steady the last few years building high quality amps as well as very consumer budgeted amps. They have amps for every type of player and every time of musical situation. They have some of the best sounding amplifiers on the market right now. NOw they are better equipping guitar players with very useful and effective distortion pedals. They have taken their ISF control knob and their award winning preamp design and put it into a pedal.

This pedal has two boosts in one pedal. This is booster pedal and also a distortion pedal that both work independently of one another and can each be switched on and off or used at the same time.


* Genuine valve design
* Operates at 300V HT
* Cascaded valve gain stages
* Responds like a valve amp
* 2 channel operation
* Clean, Crunch & Lead modes
* Unique switching operation

* Unique enhanced tone controls
* Exclusive Infinite Shape Feature (ISF)
* Fully equipped for stage or studio
* Speaker emulated output
* High integrity buffered bypass
* Power supply included
* Silent switching


This will make you have a three channel amp or it can make you get your clean amp to a distortion zone and then have a boost for solos or you can have one mega distortion channel with both boosts going at the same time. There are so many possibilities with this pedal that is makes it fun to explore your tones and find what fits you for your personal needs.

The tone of this pedal is very good. It sound like the distortion boxes that BLackstar already carries and only has one foot switch. Plus this pedal has the speaker emulated output for going direct into a PA system or to a recording session. This pedal can really do it all as preamp foot pedal. The tone is fantastic and I hate distortion pedals.


You can find these pedals new for right at around $199, which is a great price for two pedals in one. This can be simply a booster pedal or a distortion box or two booster pedals or two distortion boxes. This is a very versatile pedal. The tone is what separates this pedal from the rest of the competition. The tone comes form that famous and useful Blackstar tone that many of thier amps have. I would recommend this pedal to anyone trying to get their sound down and need a few extra tools in one to nail don their tone.

mooseherman's review"Overpriced but decent Distortion "

Blackstar Amplification HT-Dual
This is a distortion pedal that basically tries to emulate a tube amp. While there have been a few of these that I've tried, not many have really come close, so I was skeptical about this one. It is basically an analog effect. It has 1/4" input and output, as well as an "emulated output" which is good for DI as it basically is amp modeler. I don't particularly like using it but it is definitely an interesting addition to the pedal. It requires an external power supply which is 16V, which is a shame since you'll most likely have to buy a separate power supply.


This pedal has a lot of variety to it. It's got two channels on it which makes it a lot more versatile than the average distortion. The first channel has the option of being a clean boost or a light crunch, while the second channel is more of a heavy crunch. The controls feature a volume knob and gain knob (which both have separate controls for each channel). There's also a three band EQ as well as a knob labeled ISF, which operates like a presence control. The website advertised that it switches between the classic British sound and the classic US sound (basically, between Vox and Fender). I don't know if I buy that comparison but it definitely changes the sound up quite a bit. There's a switch for each channel as well as a switch that changes channel one from clean to crunch.


This pedal sounds pretty good. I definitely prefer the sound of the first channel as it goes from a lighter, cleaner boost to a relatively light crunch. It's basically a little harder than an overdrive but not as powerful as a distortion. The second channel is a lot more aggressive, and in my opinion, the weaker of the two. It definitely gives me a too-heavy vibe that I wasn't really looking for. I'm sure there's some people who would like it but it tends to be way too muddy for me. Either way though, there's definitely some good tone to be found in this pedal. It sounds great with actual tube amps as the first channel tends to bring out the warmth of the tubes quite a bit. The second channel kind of loses that sound though. It sounds equally good with a Les Paul or a Strat which are the main guitars I use it with.


This is a pretty good pedal overall. I'd say that the best thing about it is probably the first channel which gives you a nice distortion sound. Is it worth the price? Probably not, really. It doesn't really have that much more to offer me. It's certainly good but not worth 250 dollars new. I'm sure somebody would dig it, though, so I'd have to say it's worth checking out if you come across it.

Blackstar Amplification HT-Dual
(Originally written by Izzy11/translated from Audiofanzine FR)
2-channel effect pedal. I couldn't believe it but it provides a great sound palette without having to change your instrument during the song.

Effect pedal ranging from clean to crunch or slight overdrive (channel 1) and from overdrive to fat distortion (channel 2).

But watch out: it's not a distortion effect for heavy metal freaks.

It will allow you to play Guns and Roses, AC/DC, Aerosmith, Led Zeppelin, etc.

Output with speaker emulation.

Convenient PSU operation.


Quite simple configuration. You'll need time to master the ISF (Infinite Shape Feature) but it's worth it.

The ISF allows you to go from a blues rock sound to a modern US sound without changing the settings.

But the user's manual will be of great help.


I'm more than satisfied with the effects. I play with an Epiphone Les Paul Standard (Seymour Duncan SH1 and SH4 pickups ;)), Blackstar HT Dual and Marshall DFX 50.

I get a good fat sound ranging from blues to Queen, Guns and Roses, AC/DC, Led Zeppelin; etc. The sound is well-defined.

Avoid boosting the lows and highs excessively. I think it's the only disadvantage of this pedal, which actually surprised me in the beginning.


I've been using it for three months and it became essential to my setup (Marshall) and my playing style.

If it ever breaks (which I doubt because the housing is very sturdy) I will buy it again without hesitation!!! This pedal is ultra versatile and it provides the best value for money among tube pedals if you buy it secondhand. You can play everything from clean to crunch and hard rock.

I certainly don't use all its possibilities (who does?) and that's the reason I like this pedal that provides an exceptional musical value (Blackstar makes a very good use of the tube).

Blackstar Amplification HT-Dual
This pedal with two channels available:

- Clean 1 which acts as crunch with a small switch, you will have with this channel sounds typed Blues / Rock, Rock and Hard Rock and also a good clean by turning off the switch clean / crunch

- 1 channel High Gain, perfect for Heavy Metal and Metal Max Metallica / Iron Maiden etc ... no more to have a good big sound metal should he stick a clean boost input and is ultra top!!

It is 100% analog with a 12AX7 tube, the distortion is really good and does not sound at all like the synthetic metal muff EHX I had before, for example.

It also has an output "Emulated HP" Perfect to register! I have an excellent sound using this output on a mac in Logic Pro, a real massacre, this pedal is in itself a small tube amp, perfect for playing in a hotel, at home in the evening or even at night, if you do not need small parties amp you wire a sound system and you'll YOUR sound.

A huge plus!


It is on this pedal, 1 double gain knob to adjust the gain of each channel, 1 double volume knob for each channel, a 3-band EQ (very efficient) and a knob ISF to choose a typed his U.S. or UK (also very effective).

It really is a shame but it is not being double knobs everywhere to have the EQ and ISF adjustable for each channel, she would have them, this pedal would have been perfect!!


The sound quality is really TOP! One of the best I've heard! Setting this done quickly and quickly finds the desired sound, the most impressive is the HP output is really excellent!


In short this pedal is THE pedal to have on his pedalboard! The quality is TOP! Smells quality, it is a true tank over the switches do not "Click", based on the switches are very flexible and turns very easily!

Used in the value for money is just awesome!

I give it 9/10 because it would have been perfect if the EQ and the ISF was adjusted for the 2 channels.

it is simple and intuitive to qqun who has used tube amps.
The manual is easily found on the site and can help Blackstaramps some (s)
url Manual:
Attention to volumes and earnings when you plug the pedal for the first time.
All knobs are effective, the isf can be very effective as crunches or saturated, and maybe cleans but I do not use this channel.
My Classic 30 now many more sounds while keeping his true with True By Pass, element for which I am very, very hard and uncompromising: no pedal modifying the sound (to my ears) can not find places in my set the pedals.
This pedal is actually a preamp since you have the gain settings + chaquun volume of 2 channels.


My Classic 30 now sounds a lot more and I'm glad I made this choice because this amp gives a nice saturation already very saturated blues and rock pedal makes other sounds and the possibility of over saturation without being below rendering the amp ... This is quite remarkable, is not it? for a pedal.
I've made adjustments for use, it was very fast and I'm pretty manic and do not like surprises differences volumes or other unpleasant phenomena caused by pedals live.
I am not using the Clean the pedal, the clean Peavey suited me perfectly.
By now I'm against:
The Clean-amp (true bypass and it's obvious!)
Crunch pedal (with channel 1) + one of the amp, pedal respondent also very good with the guitar knobs.
Saturation-amp by adjusting channel crunch amp + guitar + by knobs
-Saturation/Boost Pedal with channel 2

So the pedal works flawlessly on the overdrive channel and the clean channel of the amp.
So I can juggle the amp footswitch for channel changes and those of the pedal that gives me a good range of different sounds out, knowing that the pedal can also very well with the knobs guitar.
Finally it is as if I now had 2 amps or 1 amp 2 channels with 3 EQ.

on the other hand: the Peavey Classic 30 this pedal does not work well in the effect of the amp loop and resumes spring reverb by multiplying the sound is unmanageable and is rotting.
So, I'll see if it does not cause me any problem later because the pedal board will evolve.


3 days as I try, I find it well above the nano pedals I used these heads for years.
This pedal is actually a compromise between saturation effect with + overdrive can quite use preamp with a direct exit to save!
This pedal is sending sounds that sounds much more like the sound of an amp as a pedal, the attack is kept harmonics and increased sustain and feedback.
This is what I heard best so far, it will suit qqun that will be very difficult at saturation effect and qqun looking for a solution without amp. or qqun that an amp that has no saturated channel, it also sounds great on the amp transistors.
When I plugged into the loop of the amp, I thought it was a scam ..
When I plugged in the input channel of the amp I was really amazed by the quality of all the sounds that can be made with this pedal.

BlackNight18's review (This content has been automatically translated from French)" Excellent"

Blackstar Amplification HT-Dual
pedal lamp
Clean / Overdrive / Lead
went emulated super awesome
adjustment: a two-stage gain 3 band eq and a two-stage level without forgetting the isf!
true bypass
adapter provides (what and very pleasant)


one branch we play I just watch the instructions for isf


of pure bomb on the warm sound of lamps
The clean is very cruch a little when you push the gain
the cruch his ac / dc, nirvana end is great
and then channel the big sound that tears his grandmother very sharp distortion for solo there's nothing better!
has noted the clean also serves clean boost that is useless ps
the isf is great you can have all the sound couleuron spends his Rican mesa boogie when we all left has his british Marshallian everything right and in the middle was the sound blackstar FYI I stay 3/4 time just right


I've had Christmas and I feel rediscover every day
more grace versatility has isf and 3 band eq
the less it is not true-bypass and that's a shame
I remake that choice without hesitation!

Overdrive & Distortion
technology lamps
adapter supplied (here it's cool)


it is very simple, quick understandable


very realistic effects. Used with a Fender Telecaster and an Ibanez AS93 very recently on a VOX AC15 amp


I use it for 2/3 years. She is great! what I like least is snoring but I love the heat. Just chopper noise gate and everything is perfect
I remake that choice without hesitation, this is one of the best products in my opinion. It brings warmth to the distortion, you get either a sound or a sound British English with ISF

Corsaire01's review (This content has been automatically translated from French)" perfect! ... except for one small detail"

Blackstar Amplification HT-Dual
Can we still talk about pedal before this behemoth?
Combined with an amp with a clean channel is obtained crunch and saturated sought is more than just a real preamp pedal.


Simple and clear without unnecessary settings.
One negative point though:
It is not true-bypass in the sense that if it is plugged into your chaining pedals and effects, it must be plugged in even if you do not activate it.
But as soon as one branch in the sector is heating lamp (lit).
In fact you must either disconnect your loop, or have fed and disconnect from mains especially when you have finished playing.


Nothing to add from other reviews read here, I would that the repetition is good, good and good again!


Excellent pedal, ideal accompaniment to an amp options a little weak or lacking personality.
Bad point though on the management of on / off non-existent, can be painful force.
Go Mr Blackstar, a true-bypass or an on / off button, please?

cyrille young's review (This content has been automatically translated from French)" SUPER REALISTIC and"

Blackstar Amplification HT-Dual
I will not go over the details and be brief. overdrive / distortion lamp (12 AX7) equalize with 3-band gain volume.


the general configuration is simple enough, the sound is always good, never read the manual. the knobs are really very effective and correct sound.


The sound is really good. I play Gibson Les paul standard and the pedal is plugged into a marshall 2466 on how low setting with retail 15-16 H 12 H body and therefore a sound that comes already in the crunch, it is the sound a plexi already pushed (master 12 H) to summarize. This is the base that I use, and I add different overdrive pedals (one at a time!) According to the desired grain ... (Xotic AC Booster, wampler plexdrive and dual Ht). Regarding the HT Dual I use to get the "big" sound, because the grain is thick enough. Channel 1 I use in "crunch" with the gain to 13 H. It really is THE sound of guns n'roses, gary moore et cie, the rhythms are splendid with its very hot and gorgeous lead, you really feel like a tube amp overdrive and despite what some may say, the light plays its part! I also changed the original, a Sovtek if I remember correctly, and I put one groovetube Chinese, on the advice of VHM, the sound is truly transformed at this time, it is become much more warm and organic with very dense harmonics ... this is the second channel, I can not really speak because I do not use it ... It's just a tone at the top in terms of saturation and there or we have an overdrive on channel 1, we go into the real Disto ... why I do not use it???? well simply because I plug the pedal into an amp with its already at the limit of good crunch (Plexi sound) ... and the big devastating distortion channel 2, a volume pushed to follow a drummer "tape" I go very quickly in feedback .... and then the sound is too compressed for my taste on channel 2. This is in my opinion the difference between overdrive (its little or no distortion and compressed (compressed sound and therefore more modern.)


I play on the pedal for a year .. I love the sound it produces including n'roses play guns and all the rock 80's 90's for vintage sounds I use pedals with a gain level and especially a smaller thinner grain. I tried another pedal in the same vein, none gave me the impression of having much more real channel on my amp (monocanal. .. which is good!) I really like this thickness in the sound and the heat generated by the lamp (especially groovetube) ... the only downside is its specific power, but it is also because of this that the lamp receives enough energy to be heated. With the experience I remake this choice ... although last pedals output Bogner esctasy blue and red, tempting me ... well they need to be tested .... but from what I saw on youtube the grain seems more exclusive than the HT Dual, which ultimately sounds like a good old Marshall stack.

Blueseb's review (This content has been automatically translated from French)

Blackstar Amplification HT-Dual
Disto lamp, and blah blah blah ... see other opinions or data sheet.


For what is the use, it's pretty simple. Turning knobs and is guided. You still need a little time to master the beast, but it is not insurmountable. It takes a few hours of practice to find the right formula.


The sound quality is definitely there. We immediately feel the presence of the lamp. effects on channel 1 and 2 are quite complementary, and congratulations to true bypass which gives comfort essential game on stage. The sound is richer and more distinct than some other distos who tend to drown in the flood of other instruments.
Special mention for the ISF is in my opinion a major asset for this pedal. In short, this is a pedal that is worth its price and weight of peanuts, it still weighs 1.2 kg.


I have this pedal for about a year and I do not regret my investment. If you want a dual channel distortion with character, try, you will not regret.
