Carl Martin Ampster

The Ampster, a single tube driven amp/speaker simulator that can either supplement your amp, or replace it. A fully analog unit with controls that are the same as your amplifier with the addition of a mute switch, a speaker selection switch and a voicing switch.
The Ampster is housed in a solid metal box with the standard EQ (Bass Middle Treble), pre and post volume/gain controls (Master & Gain) plus a Presence Control. There is a Mute Switch for obvious reasons and a Cabinet Switch with an LED Indicator light ( Red for a 2x12 Open Backed Cab, and Green for a 4x12 Closed Back Cab).
