Description
Think of this as your Ampeg amp head shrunk down to a pedalboard footprint. The Classic Analog Bass Preamp draws on decades of Ampeg amp voicing to give bassists a direct line to that thick, articulate low end the brand is known for, without needing to haul a full head and cab combo to every gig.
At the heart of the circuit sits a 3-band tone stack paired with a dedicated volume control, letting you sculpt everything from a round, vintage thump to a more scooped, modern growl. Flip in the Ultra-Hi switch when you need extra sizzle and pick presence to cut through a dense mix, or engage Ultra-Lo to add low-end weight for a fuller, more subsonic foundation — both circuits are designed to extend your tonal range well beyond the standard EQ.
Because it’s a true analog design, the signal path stays uncolored until you shape it yourself, and the signal-to-noise ratio is kept impressively clean so your low frequencies stay tight rather than muddy. True bypass wiring means the pedal disappears from your tone completely when off, which matters at the front of a bass chain where every stage adds up.
Housed in a rugged all-metal chassis, it’s built to survive load-in, load-out, and everything in between. Runs on a standard 9V DC power supply or a 9V battery (neither included), so it slots easily into most existing pedalboard power setups.
