Description
The Tech 21 Geddy Lee Amalgamation Signature Chorus is a compact, bass-focused chorus pedal created in close collaboration with Geddy himself. Designed to deliver everything from subtle thickening to studio-grade, multi-voiced swirl, it gives bassists a huge palette of choral textures without sacrificing low-end punch or clarity.
At its heart is a highly flexible Detune circuit that lets you dial in pitch-shifted voicings for added girth and width, with the option to introduce classic modulation via Speed and Depth. Engage Deviate mode and the pedal takes on an even more expansive character, as if multiple bass players are locked in unison. With an onboard Level control to maintain your volume when the effect is engaged, the Amalgamation is built to sit perfectly in a live or studio mix.
Whether you are chasing Geddy-inspired shimmer, subtle movement for modern pop and worship, or bold, wobbly textures for experimental lines and solos, this pedal is designed to be a creative tool rather than a one-sound stompbox. Every control has been voiced to help you quickly find inspiring tones that enhance your playing and support the song.
Bass-Focused Chorus with Geddy’s Input
Unlike generic chorus pedals adapted for bass, the Geddy Lee Amalgamation has been tailored from the ground up for low frequencies, with Geddy’s own preferences guiding the design. The result is a chorus that keeps your fundamental tight and defined while adding width and movement around it, so your sound remains powerful and present even with deep, lush settings.
Studio-Style Detune Control
The Detune control lets you shift the pitch of the choral voicing up or down, from flat to sharp, with a neutral point at 12 o’clock where there is no pitch shift. This gives you access to the kind of detuned, double-tracked textures usually associated with studio processing, and even allows chorus-style thickening with no modulation at all when Speed and Depth are set to minimum.
Deviate Mode for Multi-Voiced Depth
Activating Deviate mode changes the behaviour of the Detune control and introduces an additional voicing, creating a more pronounced, three-player-style chorus effect. This extra depth is particularly effective for solos, melodic lines and exposed passages, helping your bass stand out with a rich, animated presence while still feeling cohesive with the rest of the band.
Flexible Modulation and Level Control
Speed and Depth work together to shape the modulation, from slow, sober movement through gentle sway to full-on wobbly warble. With a wide speed range from 0.2 Hz to 10 Hz, you can cover everything from classic chorus to more extreme textures. The dedicated Level control lets you compensate for the volume drop that often plagues chorus pedals, so you can engage the effect with confidence, knowing your overall level will stay where you want it.
Key Features
Bass-Optimised Chorus Voicing – Specifically tailored for bass with Geddy Lee’s input, the Amalgamation preserves low-end solidity while adding spacious, musical chorus. Your tone stays tight and defined, making it ideal for both live performance and recording.
Versatile Detune Function – The Detune control shifts the pitch of the choral voice up or down, with no shift at 12 o’clock. This lets you create anything from subtle thickening to pronounced detuned textures, and even run a modulation-free chorus sound when Speed and Depth are at minimum.
Deviate Mode for Enhanced Depth – Engaging Deviate mode alters the Detune behaviour and adds an additional voicing, giving a more intense, three-player-style chorus. It is perfect for solos and featured parts where you want your bass to sound bigger and more expansive.
Level Control to Maintain Your Volume – An onboard Level control, uncommon on many chorus pedals, lets you match or boost your output when the effect is engaged. This prevents the typical volume drop associated with chorus, ensuring your sound remains consistent and present in the mix.
