General

The Tech 21 Geddy Lee Amalgamation Chorus is specially designed for the bass guitarist looking for that extra bit of depth and character in their sound. Thanks to the unique Detune control, you can easily adjust the pitch of the chorus effect to get a warm, full sound that perfectly matches bass. The special Deviate mode lets you add another vocal layer, as if you were playing with several bassists at once. You can adjust the speed and depth of modulation to your liking: from subtle and controlled to distinctly floating. Operation is straightforward and the pedal combines effortlessly with your existing setup. You simply power it via a 9V battery (not included) or with an optional power adapter.

Fantastische chorus.
Als je op zoek bent naar een chorus die door de mix heen klinkt, twijfel dan niet zou ik zeggen.
Van diepe tot milde chorus.
Hij doet het. En dat allemaal zonder veel onnodige knoppen. Het is zeer gemakkelijk om een geschikte sound te vinden.
De extra laag chorus die je krijgt door de deviate knop in te drukken, is een slimme zet van Tech21.
Ook op gitaar klinkt hij geweldig.
Top product!

Inmiddels speel ik zo'n 52 jaar muziek, waaronder bas, gitaar en drum. Mijn homestudio draait op volle toeren en deze Tech21 Amalgamation is de lekkerste en fijnste chorus die ik ken.
Klinkt waanzinnig op bas, maar ook gitaar, keys en zelfs zang.
Dikke aanrader!
