tc electronic marshall jcm800 style preamp pedal, 2 channels low and high gain plus boost. can go into an amp as an extra channel/flavour of drive or can go direct with built in cab sim, also has headphone out for silent practice. has lived on a pedal board and never gets used as was just incase my head failed at a gig to run into PA but never needed it, set up has changed so is no longer required
