I wouldn't say complete junk, but not my fav for sure.... Cheap.
If you are gonna build amps, and don't want to be on the same shelf as Boss, Rockwood, Pyramid etc, then you are going to have to build amps that people "want" not that they can "afford". There are plenty of people out there with money to buy good amps if you make them. You may not get rich, but you may not get rich selling cheapy amps either. I am not saying build the best amps on the planet, but DO stay away from the cheapy cheap prototypes, if it looks junky on the inside, it most likely is junky... If you want to discuss it more we can talk in private, you can email me
