πŸ“ About This Listing

EXCELLENT CONDITION!!!

A one-of-a-kind piece from the ’90s that made rock history!!!

Being sold due to lack of use, in excellent condition!

Stefburns modifications carried out at Mantovani!

Footswitch included!

Channel A (Clean/Crunch): Designed for bright clean tones that gradually break up as the gain is increased, reaching a classic rock crunch.

Channel B (Lead): Adds an extra gain stage via a diode clipping circuit, delivering the aggressive distortion needed for ’90s hard rock and metal.

Independent Gain: Each channel has its own gain control (0–10).

Spring Reverb: Two separate knobs to control the Accutronics reverb on each channel.

Master Volume: Two separate master volumes to balance levels between clean and distorted sounds.

Shared EQ: Bass, Middle, Treble, and Presence controls affect both channels.

Inputs: Standard – Return

Power Mode: Rear switch to toggle between High (100W) and Low (50W).

Effects Loop: A key feature for ’90s guitarists, with level control to match pedals or rack multi-effects.

Impedance: Selectable 4/16 and 8 ohms.

Chassis: Steel chassis with a multi-layer birch cabinet.
