Looking for that fuzz, overdrive or sparkly boost pedal? Karma Suture's four control layout allows you to dial in a huge range of harmonically rich tones that sound great into clean and overdriven amps. Or into a foundation overdrive, such as the Dirty Little Secret. It can work equally well with vintage single coils and hot hum buckers.
What happens if you take a NOS PNP germanium transistor and an NPN silicon transistor, plus a germanium and silicon diode, and throw them into the alchemist's pot and stir it up with plenty of Catalinbread sauce? You get a bubbling cauldron of even-order harmonics that will enhance any guitar rig!
