Used 1989 Boss GL-100 Guitar Driver rack preamp

Rackmount 2-channel analog guitar preamplifier

Very Good condition! Serviced by our in-house technician.

• Channel One (Drive/Distortion Focused): Features 5 gain/distortion modes (Drive I, II, III and Dist I, II), with Dist II emulating the classic Boss HM-2 Heavy Metal tone. It also includes dual parametric EQs for low-mids and high-mids.
• Channel Two (Clean/Transparent Focused): Features 4 modes (Flat, Cutting, Drive, and Dist) inspired by the Roland JC-120 clean tone, paired with a 3-band EQ (Low, Mid, High) with a sweepable mid control.
• Line Driver & Speaker Simulator: Built-in simulation circuitry mimics the dynamic response of large tube stacks and allows direct connection to a mixing console or audio interface without sounding harsh.
• I/O & Routing: Includes stereo outputs (Left/Mono and Right), a dedicated monitor output with a front-panel volume control, an effects loop (send and return), and a jack for an external channel-switching foot pedal.
