I just got My first G&L trib. I love it,but i'm Having a hard time with it overdriving my GK. I play mostly Hardrock/metal, and in order to cut through 2 tube amps I need quite a bit of volume. My rig is a back line 600 with 4x10, and 1x15 cabs. It's not much but it's the nicest rig I've ever had , but I just can't seem to find the right settings. Any suggestions are very welcome.
