ikay Posted May 1, 2010 Share Posted May 1, 2010 The LMIII effects loop is factory wired in parallel - OK for some effects but not ideal for others such as a compressor. I have details on how to change it from parallel to series by adjusting two jump leads inside the amp but would prefer a mod that added a parallel/series switch. I contacted MarkBass who advised that it was not possible to add a switch, only hardwire it for one or the other. Just wondered if anyone out there knows different and has managed to add a parallel series switch to an LMIII or can recommend a good amp repair person who could advise or make this mod?
