Chameleon Labs 7602 MKII Mic Pre & EQ

All knobs present and functional, instruction manual included, original power AC adapter included.

Utilizes pure class “A” circuitry made with 100% discrete components, hand wound transformers and fabricated precisely to match vintage counterparts manufactured in the early to mid 70's. Classic circuit design, polystyrene capacitors, a gold contact gain selector, and custom wound transformers.

Minor cosmetic blemishes on top & bottom, hidden when placed in outboard rack. Occasional low decibel scratch while moving potentiometers, doesn't effect output once knob is set.

The Chameleon Labs Model 7602 MKII is a single-channel, discrete Class A microphone preamplifier and three-band equalizer based on classic 1970s analog console designs.
