I'm about to add a LAR/MAR PPIMV dual 250k pot in the far left side of the rear JTM45 chassis, really close to V1. An Effects Loop kit all ready occupies the space under V2, so I'm limited on a place to put the PPIMV pot. Have any of you been successful with a PPIMV pot located here? No noise/hum/radio station reception?
On a parallel thought, have you seen the M O J A V E Plexi45 with an added aluminum plate mounted between V1, V2 and Line Dampening pot/ Line out jack, just below it? Good idea?
