Zoom G5 with Traynor Ironhorse tube amp
 

I'm getting tones of feedback from my new set-up even at low levels. Does anyone have a similar set-up as me and can help with my issue. I'm playing a Fender Srat with a hot rail pick-up on the bridge.:bonkhead:

Try raising your pickups? This has solved feedback issues for me. Either that or there is a grounding issue on your guitar. Try using a different guitar with your setup. If there is a grounding issue it could be from a loose wire on your guitar input. Do you ever have to tighten your nut around your input by hand? If you do too many times the wires connecting the input to your controls can sometimes become disconnected and this may have happened to your grounding wire. It's a pretty easy fix if you have a soldering iron.
