My Series basses are 2008 builds and both have the stereo/mono switch by the 1/4" jack socket. Possibly a stupid question, but does the switch (when mono is selected) negate the requirement for a stereo (TRS with resistors) to mono (TS) 1/4" jack lead? I was just about to order the S to M lead - as per the instructions in Mica's post and then realised that I might not need one. With mono selected on the bass, I can use all three (four if we count the kill switch) positions provided by the pickup selector knob. Any advice gratefully welcomed and this may save me a few British Pounds!
