🔥 Rare ADA MB-1 v2.05 MIDI Programmable Tube Bass Preamp – The 80s/90s Studio & Stage Beast is Back 🔥

If you want massive, professional bass tone with insane versatility at your feet (or via MIDI), stop scrolling. This is the legendary ADA MB-1 — the rackmount tube preamp that pros used for everything from clean fingerstyle and slap to aggressive rock/metal tones.

Why bassists still chase the MB-1 in 2026:

• Hybrid Tube + Solid State Magic: Two independent low-noise 12AX7 tube paths blended with crystal-clear solid state. Run them separate or parallel for thick, harmonically rich tone that no modern digital modeler fully captures.
• Studio-Grade Features: Built-in compressor, parametric EQ, contour filters, chorus, and programmable FX loops. Shape your sound with surgical precision.
• 128 MIDI Presets - v2.05 Update (expandable): Instantly switch between slap, fingerstyle, pick, clean, gritty, or full-on rock/metal patches. Pair it with a footswitch for live performance and never touch a knob mid-set again.
• Pro I/O: Balanced XLR direct out (pre/post), multiple outputs, ground lift — perfect for direct-to-PA, recording, or driving a power amp/cab.
• Works with passive or active basses and delivers huge headroom with that unmistakable analog warmth.

This thing was built like a tank in the USA and was a staple in pro studios, touring rigs, gospel, fusion, prog, and session work. It gives you that big, punchy, articulate bass tone that cuts through the mix without ever sounding thin or harsh.

Whether you're a session player, gigging bassist, or tone chaser who wants real analog character instead of plugins, the MB-1 delivers tones that still hold up against anything made today.

Condition: Excellent working condition. This was revised by a renowed electronics technician, CMOS battery has been replaced by a socket for easy battery changes in the future. Comes with: Original manual, v2.05 update manual, original laminated cheat sheet for all presets, myriad of cables.

Serious inquiries only. Local pickup preferred in Ottawa, ON - Canada OR I can ship this at yours expense. Preamp will be packed and bubble wrapped like a baby.
