I play bass guitar and have a 2008-4003 model Rickenbacker bass and a 2009-4001 C64 model Rickenbacker bass, as well as Fender Custom Shop and Gibson Custom Shop basses. I use Ampeg SVT amplification with a custom pedal board and utilize the Micro Pog and Memory Boy as part of my pedal board set up. The Rickenbackers make “exceptional noise” when engaging the Micro POG from EHX. It’s more prevalent with the 4003, maybe because of the high gain pick ups. I do “NOT” have this problem with my other basses.
