Xi (Ξ) Custom MK II

The Xi (Ξ) Custom MKII amplifier is a powerful and versatile 55W single-channel combo, with staggered gain points ranging from clean to massive overdrive and a 12" Celestion speaker.  The amp uses switches to alter the gain structure of the preamp,  so the user can control the exact point of harmonic distortion around both clean and overdriven sounds and with any  type of pick up,  either low output single coils,  or powerful humbuckers . The versatility of this amplifier is extraordinary, it ranges  from warm Jazz sounds, to intense overdrives for blues as well as extreme distortion for more radical styles. A perfect amplifier to  any requirement, both in the studio and on stage
