As its name implies, the Tweed '57 is meant to emulate the classic overdriven tones from the best Fender amps of the late 50's. Add in a three way "input simulator" switch and you'll have a hard time finding a better vintage styled overdrive!
The Decimator II features improvements in the expander tracking with ISP's new Linearized Time Vector Processing. This novel improvement provides a more linear release time-constant response for the exponential release curve of the downward expander. It also includes a LINK IN and LINK OUT allowing two pedals to be linked via a common 1/8 inch Tip/Sleeve or Tip/Ring/Sleeve phone cord allowing both pedals noise reduction signal processing circuits to track the direct instrument input.
