Vex Box of Rock on vero-board I’ll Like to see the schematic of the proyect but with the mid control that you have incluied. It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students. The sound you can get out of it is crazy and they say its all got to do with the tone stack. Many would suggest that his design was the original precursor to many of the "high gain amp" pedals that came out in the 2000's. The scope is a great tool for watching how different components and designs affect the outcome. On my HRD it seemed t be the source of the harsh tone from that amp. To control the output means we can control the Volume, Treble and Bass of the Audio output. Often in an amp with that kind of tone-stack, with no mid control theres a fixed resistor in place of a potentiometer for mids. Understandable. Here is a circuit I have found interesting. using a typical Marshall tone stack here. In addition, we add a Mid boost switch for a sound with less mid scoop and a more raw sound. See the shop page for pricing. a tone stack that blended dual filters -- one high-cut, one low-cut.
