All-tube preamp, IR technology, and compact size!

The Friedman IR-D is an entire Friedman rig in a compact, pedalboard-friendly package.

The IR-D boasts two independent, identical, foot-switchable channels based on Friedman’s legendary Dirty Shirley/Twin Sister designs.

This Friedman-modded JTM45 circuit delivers the signature British tones the brand is known for.

Powered by two 12AX7 preamp tubes, each channel delivers the harmonic richness and touch response of Friedman's finest designs.

The IR-D provides easy-to-use controls without complex menus and 100-page manuals!


All-tube Friedman tone.

The IR-D isn't simulating a Friedman tube preamp. It is one!

While many preamp pedals utilize tubes to warm up their digital circuits, the IR-D’s two 12AX7 preamp tubes, running at the proper high voltage, are this pedal's beating heart.

A genuine preamp in every way, the IR-D delivers all the tone, response, and harmonic complexity you expect from a Friedman design.


Dual independent boosts.

Both channels feature their own independent and highly tweakable Boost circuits.

This essentially gives you four channels, accessible with the tap of your foot!


Impulse response cabinet and power amp simulation.

All great tube amps need a great speaker cab, and whether sending your signal straight to the board or silently playing through the headphone output, the 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 the editing software.

You can even disengage the onboard IRs entirely to use the IR-D’s tube preamp with another IR loader.


Flexible rig integration.

The IR-D’s transparent FX loop allows you to easily integrate your favorite effects with everything from the most straightforward setups to the most complex digitally controlled rigs.


Get even more control with Friedman's Editor software.

The IR-D gives you astounding tonal control, but its included editor software and MIDI capabilities take it to a new level.

With the Editor software, you can tweak each channel’s power amp simulation, load your favorite IRs, activate the Boost Lock feature, select loop ON/OFF, and save it all to 128 MIDI presets. The IR-D truly is the perfect marriage of modern control and classic tube tone!
