Friedman IR-D 2-Channel All-Tube High Voltage Preamp

The Friedman IR-D dual-channel tube preamp is an entire Friedman rig in a compact pedalboard-friendly package. IR-D boasts two fully independent identical foot-switchable channels which are based on Friedman’s legendary designs. This Dave modded JTM45 circuit delivers the signature British tone for which Friedman is known for.

Powered by two high-voltage 12AX7 preamp tubes, each channel delivers the harmonic richness and touch response of Dave Friedman’s finest designs. DSP IR cabinet/power amp simulation sends a studio-quality mic’d-up tone to your DAW or Front-of-House. The IR-D provides easy-to-use controls without complex menus and 100-page manuals.

IR-D isn't simulating a Friedman tube preamp. It is one. While many available preamp pedals utilize tubes to 'warm up' their digital or solid-state circuit, two glowing hot 12AX7 preamp tubes, running at the proper high voltage, are this pedal's beating heart. A genuine preamp in every way, IR-D delivers all the tone, response, gain characteristics, and harmonic complexity you expect from a Friedman design.

IR-D boasts two fully independent identical foot-switchable channels which are based on Friedman’s legendary Dirty Shirley/Twin Sister design. This Dave modded JTM45 circuit delivers the signature British tone for which Friedman is known for.

Both channels feature their own independent and highly tweakable Boost circuits. This essentially gives you four channels, accessible with the tap of your toe.

IMPULSE RESPONSE CABINET AND POWER AMP SIMULATION

All great tube amps need a great speaker cabinet, and whether sending your signal straight to the board or silently playing through the onboard headphone output, IR-D gives you a selection of Dave Friedman’s favorite IRs. Select the IR per channel using the 3-way mini toggle switches or load your own quickly and easily via Friedman’s editing software. You can even disengage the onboard IRs entirely to use IR-D’s tube preamp with another IR loader.
