Value For Money : Excellent
Tube amp 100W
Power is supplied by four 6L6GC, 6L6GC STR TAD of RCA base.

The preamp section that consists of five lights, V1, V2 and V3 are 12AX7 WA, then a 12AU7 for the last loop and a 12AX7 WA in IP, 5 lamps are Sovtek.

The amp 4 channels, clean, crunch, OD1 and OD2 each with a volume and gain. Clean and crunch channels each have two modes, warm and bright and clean to crunch, supercrunch for the second.
Clean and crunch channels share the same EQ with classic, bass, midle, treble and an ISF knob.
OD1 and OD2 channels share the second equation similar to the first.

Comes the master section, with presence and resonance controls, a master general and DPR side, a system that can reduce power up to 10% but not that.

At the rear there is a jack and XLR line out, an effects loop with a button or 4 DB - 10DB, 2 speaker output that is controlled by a knob for 4/8/16 ohm jack and footswitch.

Otherwise a very nice aesthetic with a solid head and a black logo 6L6, all displaying rather clearly that she wants. A perfect finish, not a single fault at this level!


Configuration is fairly simple, not rocket science.

The manual that comes with the head is very clear and provides a very good starting point to understand the beast.

Knobs react very well and they are all useful. I found a great complementarity between the knob and bass resonance that really helps sculpt the bass / lower midrange to sound rather sharp or rather thicker with large shade.

The ISF is very effective on this amp for a change the voicing of the beast, perhaps a flat knob on the right side of the race (English) who spent 7 darkens the sound a little too especially with saturations.

DPR works well, but do not do this illusion, even at the lowest power delivered is still important. This is the responsiveness of the master general who can be able to play in the same. This is a very good tool to control power according to the situation repeats, small, large room.


I play mostly death metal, I plug in the head on a small HTV 212 which I replaced with 2 celestion 80 Man'O'War Eminence.
I plug in either my guitar BC Rich Stealth, my BC Rich in virgin sh4 / 2 or my ESP NV SD blackout.

Clean sounds, not having a lot of amps test on clean sounds I can not compare it to others. It is this strength of this versatility, modes, and one equa effective LAI, there's plenty to do. I have a weakness for fashion with beautiful warm sound rather low and hot, with a TFR which tends strongly to the left for a clear and clean end. A report that is clear is that very clear on the long run the gain knob, allowing for a clear sound with good power reserve, and does not suffer from a lack of power compared to other channels as on some heads.

The crunch channel is a weak point for me, I find it quite right, but great personality and he tends to go quickly and distortion for voice I think. I think that it was not designed to be a real good crunch but for a small distortion boostable. The I find it really useful is that it allows for a third possibility of distortion and therefore have everything under foot. Concrete example, I mainly play on my rhythm a little OD1 and OD2, OD2 on the solos and I use the crunch mode or even great for arpeggios plans or plans with some dissonant sounds, to bring out the notes.

Here the best, OD1 and OD2, we go with the very large distortion although the super crunch comes there too. The OD1 a distortion a little more open medium, where OD2 is more compressed, dark, mediums more accentuated.
Again the torque equa master and do a great job, you can really shape the sound we are looking for an edge to his thrash or rather a response in the low / low mids larger for large PM. Personally I mostly use OD1 to have a style rather his death 90 years, but spend a great riff Bolt Thrower on OD2 is just enjoyable. I use OD2 rather lead sound a little dug allows me to have midrange / treble less aggressive while I rest on the bridge pickup.

I explained that it was a head fairly quiet with very little wind.

A 9 because it lacks a real crunch but me it does not bother me instead.


What I like most is that versatility, control is the sound.

I have not tested many models before, the blackstar HT, H & K, a little marshall too. What I have to decide what it is exactly to my specifications.
I wanted a head high gain, 50/100W with at least two separate equa channels and a master section complete, XLR output. Then, the DPR, the ISF, 4 channels, whether blackstar is a brand that I know and finally nine attractive price convinced me.

We have a 4-channel 100W head with many controls, very versatile and a perfect finish for about € 1400 new. For me the price / quality ratio is excellent.

Personally it meets all the criteria and I would put him around 10.
Objectively could regret the lack of reverb, a fairly substantial weight, not really a crunch crunch and resonance / presence common to all channels. But the price is certainly not the same.
