Tech21 Geddy Lee YYZ Signature Sansamp (YYZSH) The Geddy Lee MP40 Limited Edition Signature SansAmp sold out so fast, it made Tech21 heads spin. Out of respect for the limited number of MP40s featuring a custom “Moving Pictures” inspired artwork, They are offering the Geddy Lee YYZ Shape-shifter Signature SansAmp. It has the same colour scheme and graphics as Geddy’s other Signature SansAmps (GED-2112 rackmount, DI-2112 desk-top, and YYZ single footswitch pedal), with the same features and functionality as the MP40. The YYZ Shape-shifter SansAmp includes the addition of a selectable Boost stomp switch, providing a 12dB presence boost for increased top-end distortion. Engaging the Shape-shifter button adds 6dB of Schmegilka on top, which, according to Geddy, “is an indefinable thing of awesomeness!” Operable with a 9V alkaline battery (not included) or optional DC power supply, Tech 21 model #DC9 (or former models #DC2 or #DC4).
