Description
The Ampeg Classic Analog Bass Preamp is a compact stompbox designed to replicate the signature tone and response of traditional Ampeg vacuum tube amplifiers in a pedalboard-friendly format. It features a three-band tone stack comprising bass, mid, and treble controls alongside dedicated Ultra-Hi and Ultra-Lo push-button switches for instant frequency contouring. The circuit includes an internal -15 dB input pad jumper to accommodate active instruments with high-output pickups and prevent unwanted input clipping. Housed in a durable die-cast zinc chassis, the unit relies on hardwire bypass switching to pass the dry signal cleanly when deactivated. It operates on an external direct current power supply or an internal nine-volt battery.Media
