Mad Professor Ruby Red Booster
The Mad Professor Ruby Red Booster is a great little guitar booster pedal that has more control than your average boost pedal. The pedal has a pretty standard make up as far as general characteristics go, with 1/4" connections for input and output and requiring power from a 9 - 18 volt power supply. However, the internal characteristics are anything but standard as it's got two booster in one here and also has a switchable buffer on the inside for helping not to lose signal when using it with other pedals. It has true bypass and isn't rack mountable...


You don't need to know much in order to use the Mad Professor Ruby Red Booster as it's a really simple one to get used to. The parameters that it gives you to work with are for boost, treble, and master. Each is kind of it's own little effect in itself, as turning each up will have a pretty drastic effect. A manual shouldn't be necessary here - just mess around with it until you feel comfortable.


The tone of the Mad Professor Ruby Red Booster is absolutely perfect. It's super smooth and there's a lot that can be done with it considering it's 'just' a booster pedal. You can use it as more of a full bodied boost, a treble boost, or even for some straight up overdrive. If you were using a tube amp and a great guitar, you could probably get away with just using this pedal and have a nice array of different sounds here. The main thing to consider here is the flexibility, as you aren't going to find these kinds of options on many other booster pedals.


If you're looking for the ultimate guitar boosting pedal, you need to take a serious look at the Mad Professor Ruby Red Booster. It's a booster by trade but has the flexibility to be an overdrive or simple treble booster as well. It's definitely not the cheapest booster out there, but it's also not incredibly expensive considering the incredible tone quality here. If I was buying a booster pedal and money was no object, I'd definitely be going with the Ruby Red Booster.

Dime_RIP's review (This content has been automatically translated from French)" THE Boost"

Mad Professor Ruby Red Booster
To summarize, this pedal is a mix of two legendary boosters of the brand (the Little Red Trebler and Red Rooster Booster) which, depending on the settings, get (alone or in combination):
- A clean boost
- A treble boost
- Overdrive

This pedal has a Buffer activatable switch to domestic and, there is the possibility of the return to true bypass therefore

while analog is

3 controls:
- Master (manages the signal level)
- Treble (manages the acute level - from 0 to 15 db)
- Boost (manages the boost level, 0 to +40 db - see it as saturation)


nothing more simple, turn the knobs and felt the effects immediately.

manual (in English) is clear and explains concretely on what knob play for a typed config

- Treble boost (to summarize, the master latch, boost minium)
- Clean boost (to summarize mini treble, master and boost to catch on)
- OD (to summarize, boost the cleat, master office, ditto for treble to adjust the color distortion like a tone)

proposed, for example, but there are demos on the net (youtube) if it does not seem clear to you (but it is clear and you can hear it right now) no adjustment

a good representative video, I regret that do not use high gain version'''' as it is also perfect in teble boost mode for a pest would sound like a Tube Screamer, staining in less .. .... it is a matter of taste


super transparent pedal, well done to the buffer if you have a string in front of the pedal to puke (my case) and meters of cables

I use 2 amps completely different: a replica Marshall JTM 45 and Engl Savage with double coil guitars ... 2 worlds so

The Engl, I use way more treble boost OD Tube Screamer for more gniak and the JTM45, so more distortion or clean boost, on super strat (config HH) with one or more of the strat (config SSS or HSS) on the other

It adapts well to the grain of each and every guitar amp ... I find that quite a few colors ... like some other non-


this is the ultimate versatility in a small pedal I recommend
I have owned, sold and bought so I missed her

I admit I did not try many boost (from Xotic, the mxr) but the interest with this one is that it helps to have 3 pedals in one and the new price is not exorbitant

Pedal advise!!

be23's review (This content has been automatically translated from French)" A must have!"

Mad Professor Ruby Red Booster
Pedal to do everything, which has three main functions:
- That of clean boost
- The overdrive
- That of treble boost

An internal mini switch lets you use the pedal in "true bypass" mode or "buffer" to avoid that the signal diminishes if too much is used chaining effects, and / or the case of using long lengths of cable.

The finish is neat, although I agree with the previous opinion to say that the perceived quality is slightly lower than the pedals "Handwired" of the same brand, but it's still a pedal robust and well finished.


Not need any manual, here it is three knobs and basta.
We try 10 minutes, turning in every direction, and we understand very quickly who is doing what:
- The knob "master" manages the signal level
- The knob "boost" varies the saturation
- The knob "treble" manages the level of high frequencies.



It is the star of my pedal pedalboard. Yet I have had other pedals from the same brand, including versions of "handmade", but if it is certain that each is excellent, none seemed as vital as this one.
Can not find non-musical settings, even putting the knobs in the extreme positions.
Contrary to what is reported in the previous opinion, I have had for me no extraneous noise of any kind reported.

I'll try to summarize: the Ruby Red Booster is a very transparent pedal, which follows closely the sound of the guitar and amp on which we play.
The amount of boost is phenomenal (40 db), all controlled by a knob very linear. By pressing the second knob, the sound twists, and a delicious overdrive very open springs from HP ...
Forget the tight grain of some overdrive "typed", here we are in line with the clear sound of your amp, so if like me you've fallen in love, you'll like! Note that the overdrive can be obtained very couillu if you push the knob "boost" beyond 15 hours ...
And finally, the icing on the cake: the treble boost. I play a Les Paul, and I sometimes need my rhythms are sharp, they emerge from the mix. Well bingo, the solution is in the box. And even forcing the knob "treble", I never get too intrusive treble, giving the famous "bee" in the eardrums.

In short everything is there, all functions can be assayed independently of each other, and everything is deliciously musical genius.


I use this pedal since not far from one and a half, and I must admit that if it should remain a single pedal to put in front of my amp, it would be this one, all others seem to optional side.

Mad Professor is expensive, and even if the versions "factory" are a little more affordable, it's still not cheap.
But I think it is better to save to buy a very good pedal rather than buy 4 medium.

To conclude, I would say that among the thousands of existing pedals on the market, the Ruby Red Booster is part of the exclusive club of those that can not live without when you have enjoyed, in short a "must have"!

Le Mercier's review (This content has been automatically translated from French)" Good product, but ..."

Mad Professor Ruby Red Booster
Pedal with three distinct functions: a clean boost of 40db (that's huge), a treble boost of 15dB and a function "buffer" switchable from within.
To summarize:
3 knobs:
Volume (Master)
a clean boost (Boost)
and treble boost (Treble).
A true-bypass that can be converted to bypass with buffer to boost the signal of your guitar when used many pedals "true-bypass" (the problem does not arise a few years ago, as all the pedals were to "buffer" against it was found by a color signal of the guitar after what we went up like effects ...) or to compensate for the loss of signal strength of a long cable ...


For use ... nothing fancy, you plug one turns the buttons and that's it ...
Where it gets complicated is the use with other pedals, because depending on what you want to do, the setting will be completely different (eg, the master will be used to boost an OD) I think this pedal instead is made to operate only on an amp and all lights but it is a very personal opinion

A mini external switch would have been more convenient to bypass the "buffer"


In terms of sound quality not too disappointed: it is transparent and the "boost" is very effective on a tube amp (Vox AC30 CC1) it moves ...
As for the "treble booster" nothing beats a TS9 or TS808 gain 0 (matter of taste) but the result is still the appointment, and awfully good with a Start

As for other boost pedals down there, it gets stuck because one can force parasites!

buffering option is very transparent and very effective and in my opinion a strong point ...


This model is part of the new series from Mad Professor and it is clear that the quality provided to older models of the brand is no longer valid:
Significant progress on the packaging, price squarely down and when you open the pedal, it feels the industrial base ...!!!
It's a shame because practically the entire range has been lowered and handmade probably will become less frequent ...
Advice, those with Mad Professor handmade, keep ...!!! because I think in the near future prices should catch fire because they are all models except the nival sound qualities as well as manufacturing, rather than the new series, and there, the term "BJF Design "is clearly set to sell because it is west of the original model BJF ...
Obviously, the price dropped and it is still a good pedal, but the background in the mass of industrial and other pedals is not what is expected of a Mad Professor, let alone a BJF Design ...
I would do it clearly does not choose this pedal because I'm a fan of pedals exceptions and there is no longer the case, as a bonus, new at Mad Professor:
parasites! absent on the first models on the same distortion and fuzz

My opinion would have been less severe if I did not have other Mad Professor ...
But here, I have five of the older generation. Certainly, they are all handmade and is price accordingly, but then the quality is really the appointment and stamping BJF is not for sale, some say they are better than BJF original and I think so too ... it's a shame, this policy shift to try to make improper, it breaks a little myth ... certainly for economic reasons ...
