It 's really a great pedal! The simplicity of use is amazing, even without knowing English and then not being able to take full advantage of the user manual are managed in a short time to make a satisfactory use in its features. Beautiful the boost button .. you charge the guitar vitamins and it seems that doubles its power and fullness of sound for solos .. really nice .. the usual distortions in most multi-effects pedal seems generated by a swarm of mosquitoes ... the following is a pedal that lets you really pull off something stronger from your sound ... If you are using a final stereo and two quality speakers all is enhanced even more .. of course the price is high but so much force to look decent sounds with various pedals and pedals several eventually spend them anyway not coming to this result ...

Do you like big sound?

Patrick B. 628, 18.10.2016
I bought this pre-amp pedal (very expensive it is true) after seeing the demos of Ethan BRUSH etc ... telling me that our friends from THOMANN would take it back in 30 days if I was disappointed.
Well I kept it because the sounds are excellent for the vast majority.
Do not look for the complication, you will not find hundreds of settings for computer scientists but a pedal to play EVERYTHING.
It is aimed mainly at fans of big sounds.
The settings really affect the sound and make it possible to achieve what you want on any type of guitar cabinet (eg unique settings of bass, treble etc ... which affect all presets -> nickel when one Changing room or cabinet)
Special mention for the natural side of the sounds and for the decimator which is magnificent (no breath and no planing of the sound even with huge distos).
I'm really a fan because the guitar pedal cabin couple gives impressive results.
Small disappointment by cons for the results obtained with the direct output (to mixing table where speakers amplified with the system emulation speaker leaves me a little on my hunger and less good than announced.
Conclusion: It's all good for home and live and this system supports comparison with many tube amps (I have several)
