Simpler is not possible.
(See descriptions below)

UTILIZATION

Very convenient to feed on the sector: the same 9V adapter for the pedals.
If we wanted to simplify it would take away the input jack!

SOUNDS

I would not do a quote from a comment below:
"This amp is the sound!"
It gives what you have in your fingers ...

OVERALL OPINION

As mentioned there too, this is not a toy: the second half of the instrument.
- You play what you?
- I play guitar / Pignose.

Around 10 because it is unique in its class.

Only possible improvement: dress with fur milka cow, but that's another story
