Product Information

A Detune knob that sweeps the chorus voice sharp or flat is what separates the Geddy Lee Amalgamation from the average modulation box. Tech 21 developed this bass–specific chorus with Rush's Geddy Lee and his tech Skully, aiming for something warm, thick and dynamic. At 12 o'clock there is no pitch shift at all, so with Speed and Depth wound back it becomes a straight detuned thickener with no wobble.

Speed sweeps the modulation from 0.2 Hz to 10 Hz, while Depth takes it from subtle movement to properly seasick. Level is a rarity on chorus pedals, letting you compensate for the usual volume dip when the effect engages. Deviate mode changes how Detune behaves and adds a second voice, giving the effect of three players on the same part. That makes it a handy footswitch–ready boost for solos or choruses where the bass needs extra sizzle.

The pedal measures 3.75″ x 4.75″ x 2″, so it slots onto a crowded board without drama. Power comes from a 9V alkaline battery (not included), or from Tech 21's optional DC9 supply. Studio–style choral tones that normally need rack gear or a plugin chain are available at your feet, with controls broad enough to cover subtle shimmer through to full–blown modulation.
