Friedman IR-D Dual-Channel Tube Preamp Pedal

Vintage-Inspired British Tone with Modern Direct Flexibility

The Friedman IR-D is a full-featured dual-channel tube preamp pedal designed for players seeking the legendary Friedman tone in a compact, pedalboard-ready format. Based on Dave Friedman’s modded JTM45 circuit, the IR-D channels the essence of his acclaimed Dirty Shirley and Twin Sister amps—delivering rich, touch-sensitive vintage British overdrive, dynamic cleans, and harmonically complex crunch tones.

Loaded with two high-voltage 12AX7 tubes, the IR-D offers true tube saturation and feel. Its intuitive interface includes dual identical channels, onboard TS-style boost, studio-quality impulse response cabinet simulation, and deep MIDI integration—making it an ideal rig solution for live performance, recording, and silent practice.
