Friedman IR-D Dual Tube Preamp And DI

Expanding Your Sonic Palette with the Friedman IR-D Dual Tube Preamp And DI

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.

All-tube Friedman Tone

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.

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.
