Hey everyone, I'm not new to TB but this is my first post.. I'm having a horrible time figuring out what is wrong with my current setup and I need as many brains as I can get to help me out. I've been using a 2005 American Jazz with S1 switching going through a Boss tuner and an Aguilar Tone hammer into an older Peavey TnT115. So it seems that in the middle of my last 2 sets playing out my sound seemed very thin and inaudible. At first I thought it was the amp so I tried another amp at a show which was a friend of mine's older SVT, and it STILL seemed way under powered. At that point I took the jazz bass to a local shop and he had the bass for almost 2 weeks and swears everything electrical is solid. Cable tester says cables are fine too.. Any thoughts?
