This series of onboard preamp systems represents another innovative leap in design. Advanced controls are combined with our patented 'fliptop' housing (pictured below) that enables the preamp chassis to pivot out of the guitar for easy access to the 9-volt battery. Most often seen as the choice for original equipment on many prestigious brand name guitars, the Prefix series is available for after market installation by any experienced repairperson.

Advanced Feedback Fight Features - The Prefix Plus system contains all the features of the Prefix system, with the addition of a brilliance control, a notch filter & a phase switch for fighting feedback.
