Simple and effective I use this amp in the studio for 8 years and in sound when you know
BUD amp to use no problem!
Compete with a vox amp one night the Vox beef dropped .... not him!
The rglages are fine and I confirm that this amp gets the ending for vintage loose some brands I've used.
All types of sounds are possible!
With 20 watts of course must not be Bercy without using a recovery console!
8 years of use without any problem!
There is more but I do it again this choice without hsiter!
