This is my clone of the original Prescription Electronics Depth Charge Bass Fuzz which are no longer available, getting very rare, and commanding very high prices these days ($700! and up). Mine comes in a much smaller black and silver 125B enclosure and uses the same 2N1307 transistors with the same knob layout and type as the original. I etched and tin plated my own pcb for it. It also has ALL top Lumberg jacks and high grade Wima capacitors and a relayed true bypass. This is the nicest sounding one that I've ever made
