The Tech 21 SansAmp TRI-A.C. packs three classic amp personalities into one rugged, fully analog pedal. Each channel is fully programmable, letting you store your favorite gain, EQ, and level settings for instant recall, perfect for both stage and studio use.

While originally designed for guitar, I’ve mainly used this unit for bass, and it’s absolutely fantastic for it - delivering warm, punchy, amp-like tone with grit and clarity. Thanks to its flexible EQ and drive controls, it also works brilliantly with lap steel, blues harp, or any instrument you want to add character and amp-style drive to.

Key Features

• Three Customizable Channels: Switch between clean, crunch, and high-gain tones instantly
• All-Analog Signal Path: Classic SansAmp warmth and responsiveness without digital harshness
• Versatile Amp Emulation: Covers Fender sparkle, British mid-push, and high-gain distortion
• Direct Recording or Live Use: Sounds great into an amp, mixer, or audio interface
• Built for Any Instrument: Guitar, bass, lap steel, harmonica - whatever you want to give some tube-style grit
• Roadworthy Construction: Metal chassis, built to last

Condition: Used but in excellent condition, fully functional, and well maintained.

Reason for Sale: I’m only selling because I have two of these pedals, and this one isn’t part of my main rig anymore.

The TRI-A.C. is a workhorse preamp that captures the soul of real amps in a pedalboard-friendly package - flexible, musical, and perfect for players seeking pro-level analog tone for multiple instruments.
