Well, in this area, no need to add, Gromeul has already said it all!

In any case, the deposit amp (I had before buying a Peavy classic 30, and frankly, I see no difference in power between the two). With the volume at 3 in the clean repeating, I get along well.

In addition, the extensive connections on the rear panel opens enormous possibilities and very practical, especially with regard to registration

ditto for the switches "bright" and "mid shift" on the front panel that allow real access to a wide range of sounds.

And best of all, this little amp really looks nice, the finish is exemplary.


Get started easily enough, despite all the switches and inputs (rear) of the amplifier.

Indeed, if the equalizer is common to both channels, the switches "bright" and "mid shift" can really fine-tune the sound;

In addition, the setting knobs are very sensitive and have a significant impact on the sound. 2 is not 2.5 or 3! So we need a little time, once you tried different config, to find her, but once this is done ...


... Ecstasy! The clean sounds are amazing clarity and accuracy. What is nice is that the amp does not crunch very quickly (unlike a Fender Deluxe Reverb 22watts I tried), so we can grow quite the volume before the sound begins to saturate.

The switch "bright" gives you access to many sounds, to sounds worthy of the best fender, while the switch "mid shift" will allow you to focus on the midrange, though nice for out of a mix.

I find its relatively neutral, but clean and detail that will really highlight the nuances of your instrument, thus enhancing, and each tone.

I said that I connected to one of my cabinet design, with a Celestion V30.

In addition, between switches and knobs, you can access any type of real register sound, from the vintage to modern. In short, you'll understand that this amp is really versatile and can adapt to any style, from jazz to rock (and derivatives), blues, to metal (possibly with the addition of adequate distortion pedals).

However, I was a bit disappointed with the reverb, which I find somewhat artificial (on this point, I preferred that of my C30), especially when riding, but do not grow beyond 4 , it still makes a lot, and channel 2, ie the overdrive.

On this channel, which is common with the Equal channel clear, there are two additional switches. One of them is used to select channel 2 in the main channel, while the other plays the "stamp", the tone of the overdrive (lo> hi). The footswitch allows you more access to a "more drive". Yet these multiple possibilities are misleading in my opinion because I expected more vast and sonic surprises, gold, it is not, even if everyone will find for sure his account in looking around.

the issue, I have mixed feelings, especially by pushing the gain and tone (high): it is super clean (too much for my taste), and sounds a bit "artificial", fade, especially "more drive".
In "high", it sounds too typed "hard rock 80-90" in my opinion.

I use it only in low mode (the only usable for my taste, it is essential), with the gain to 6: it produces a warm overdrive and nervous at the same time that complements and blends well with my other distortion pedals, although I prefer the sound of these.

Anyway, it's really to quibble!


I use it for several months, and I do not regret at all the investment. I find the price / quality ratio really good (I got it to 900 euros, switch provided some brands should build with the provided cable hp), especially taking into account the enormous range of possibilities, both noise level of the use (studio, scene ..).

In addition, Class A materials exude quality really, it's tough!

I had previously a Peavy classic 30, and there's no pictures, it brings us to another class tube amplifier.

I tried a vox alnico blue acc30 I found friendly without effects, but with less convincing, the fact that you can not adjust the midrange is annoying because when you use a wah, it becomes really Screaming. In addition, it does not necessarily marry well with any distortion pedal. In addition, it is much more "cheap" (including trim).

I also tried a classic ENGL 50 which I really flashed, but coming out of my budget (head at 1250 euros). In addition, its sonic possibilities and use are much smaller (here, we stay in the field of vintage) than those of Studiotone, although engl has two reverbs (one per channel). But what would I do with 50 watts, while 20 more than enough for my use (apart, repeat, little scenes)?

In the end, a choice I would definitely do it again, because you can access this stuff to the professional type, at a price of more attractive (at the price I got it, of course).

Come on, the only criticism I would make him really is his name (pronounced "Kotch" to tell the Dutch), but hey, the important thing is the sound, right?
