Friedman IR-D 2-Channel Dirty Shirley Twin Sister Tube Preamp Pedal

The Friedman IR-D puts the signature crunch of the Dirty Shirley into a compact all-tube preamp pedal. Powered by two 12AX7 tubes, it delivers the responsiveness and complexity you'd expect from a Friedman design. With two independent channels equipped with boost, you can footswitch between four distinct gain stages—from pristine cleans to saturated distortion. Built-in IR cabinet simulation sends your tone direct to a PA or interface, complete with studio-quality mic'ing. The Friedman IR-D provides an intuitive control set without burying key parameters in complex menus. Just plug in, dial in your tone and unleash iconic Friedman sound anywhere your pedalboard goes.

Key Features

• Danger, Danger, High Voltage - Two high-voltage 12AX7 preamp tubes for rich harmonic tone.
• 2 Channels Bass Boosted - Two independent channels with boost based on Dirty Shirley/Twin Sister circuit.
• Studio Quality Tone with IR's - Onboard DSP IR cabinet/power amp simulation for studio-quality tone.
• Plenty of Friedman Cabinets - 13 Friedman Cabinet IRs included; load your own IRs via Friedman Editor software.

Savour the Tone of Glowing 12AX7 Tubes

While some preamp pedals use tubes merely to "warm up" their solid-state circuits, the Friedman IR-D is built around two genuine 12AX7 preamp tubes. Running at proper high voltage, these tubes infuse your tone with the touch-sensitivity, harmonic complexity and gain characteristics that define the Friedman sound. The IR-D reacts and responds like a real tube amp, not a simulation. You'll hear—and feel—the difference, from dynamic clean headroom to rich, reactive crunch.

Two Channels Become Four With Independent Boosts

The Friedman IR-D equips each of its two independent channels with a dedicated boost circuit. Essentially, this gives you four distinct voices to craft your ideal gain staging—from pristine cleans to roaring overdrive. Each boost is highly tweakable via the Friedman Editor software. Access two channels at the stomp of your foot, while the extra boost kicks transform the Friedman IR-D into a versatile tone toolkit. The channels themselves are based on Friedman's famed Dirty Shirley circuits, dialing in those coveted British tones.

Onboard IRs Put World-Class Cab Tones at Your Feet

Thanks to built-in IR cabinet simulation, the Friedman IR-D consistently delivers studio-quality mic'd up tones no matter where you plug in. It comes loaded with 13 of Dave Friedman's favorite IRs, from classic 4x12s to more exotic combos. Easily select an IR for each channel with the mini toggles. The onboard IRs can be bypassed entirely for use with your own IR loader. Whether recording direct or playing live, the IR-D equips your pedalboard with an arsenal of iconic Friedman cabinets.
