I am quite satisfied. I just reworked to replace fragile things (eg plastic input jack - Input jack transformed into metal). Power is extremely strong. There are many settings and a few effects. Good for playing rock or things like that. Having changed the enclosure, I have converted the amp to the back of the piano in my group.
The configuration is not easy for a beginner. This gives a very good sound, clear sound. The manual is very satisfying.
This too is not suitable to my style of music. But having a little touched up, the amp is perfect for a piano back. I play it with an electric piano, but more generally with my electric guitar I do not remember what brand.
For 8 years, and had already been used by a musician. I have tried many models, but this one really liked me.
