Crazy Tube Circuits - Crossfire

Crazy Tube Circuits

Crossfire is inspired by one of the most iconic pedal - amp combinations in guitar history.

The left side is voiced after the blackface amps that defined clean electric guitar sounds. Following the circuit path to the exact detail we managed to include all the essential sonic ingredients. From the big bold lows, sparkly highs and slightly scooped mids, to the powerful sound of a solid state rectified 4x 6L6GC power amp or the sponginess of a tube rectified 2x 6L6GC power amp selectable through the headroom switch.

Match that to the green mid-hump overdrive we’ve all grown to love, upon its inception in the late 70s, found on the right side. We chose to accurately recreate the circuit of this classic overdrive but with the addition of some of the most common modifications the pedal has seen throughout the years of its mass production or boutique variations. A clipping toggle switch selects between symmetrical (original) or asymmetrical clipping for enhanced touch-sensitive drive characteristics while a gain toggle adds more gain and alters the low frequency response making it reminiscent of placing two of the same overdrive pedals in series. An internal switch offers additional headroom by providing 18V DC to the overdrive circuit.

Warning: This unit was designed for 9V DC input only. Do not use a higher voltage power supply.

A passive effects loop gives you the option to connect your beloved pedals in the signal chain building your ideal rig or use the two sides independently (send is the output of the overdrive side, return is the input of the amp side). When both sides are in bypass mode the loop is true bypass as well, so your signal won’t be affected at all.

It’s a match made in heaven! Turn your rig into a screaming sparkly blackface machine!
