I need some help here before I go postal. When I play my guitar (which has new slinkys and is tuned to concert pitch) it sounds flat. When someone else who has been playing a lot longer ( one guy has a fusion jazz band the other was giving me lessons) it sounds terrific. I'm playing the same notes but the sound is dead, no ring no sing and Im getting p-ssed. Anyone have any ideas?? Dont say buy some gizmo either. If you aint got tone with just the guitar and amp no pedal is going to give it to you.
