After a lot of designing, redesigning, scrapping and discovery of things I didn't know existed, the plan morphed into:
An all-in-one guitar amplifier based on the legendary Marshall 2204.
This was to be controllable by a touch screen.
It was to have space for twenty presets.
It was to have midi capability.
It was to have a zero loss effects loop.
It was to be programmable using an android app.
