I have this amp but when I play my Ibanez Artist with Seymour Duncan Lil 59 or my strat on the g and b string I get a fairley loud ringing tone after I hit the string.. I have lowered the pickup and in the amp went straight into the effects return to just use the power amp and still get the ring. Tried a 31 band eq in front and in the loop to try and take it out to know avail. Any ideas. At first I thought the preamp tubes might be going, but I believe when you go strait into the effects loop it by passes them Any ideas are welcome.
Thanks
