• Image of Swamp Hammer Overdrive

Using the classic TS-style overdrive as a starting point, this unit incorporates a number of the often favored modifications to create what is personally my favorite blend of features and tones for a smoother response and higher gain than the original.

Noted changes to the original circuit include:
RC4558P IC
MPSA18 input transistor
Clipping switch with asymmetrical silicon vs. LED & germanium blend
"Fat" switch for increased bass
Some minor value changes to input impedance and feedback loop
808 spec value resistors in the output stage


Top-loaded input jacks
Standard 2.1mm 9V DC power jack with negative center pin
True Bypass
Bright green indicator LED
