Hi folks. My first post here. I just got a new 65 PRRI and have the usual "big purchase" paranoia that it may have issues. Here's what I've noticed: Slight pop/crackle when inserting/removing guitar cable in either instrument jack, even with volume off. (I'm upgrading from a Boss Katana 50, which is silent). Tremolo intensity knob has no noticeable effect until "5", at any speed setting. Volume knob is stiffer that all other knobs. Normal behavior? Thanks!
