How do I get rid of that @#$%^ ghost note problem in by Bad Cat TremCat 30 1X12 combo? The only way I can play the amp without hearing ghost notes is in 15 watt mode with a 1X12 extension cab added and the amp set at 4 ohms.
When I am running the amp with the single 12" speaker (no extension) at 8 ohms, the ghost notes are absolutely intolerable.
What am I calling a ghost note? The deliberate note I'm playing comes through loud and clear along with another "ghost" note at around 50% of the deliberate note's volume. The ghost note is a sour discord in a different key than the deliberate note - not at all similar or complimentary.
