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 $650-$800). Mine comes in a much smaller polished and etched 125B enclosure and uses the same 2N3707 transistors with the same knob layout as the original.It also has ALL top jacks (Lumberg), high quality WIMA capacitors and a relayed true bypass. I'm only going to make ONE MORE available for order.
