Dual Terror, reducing feedback at high gain?
Posted: Tue Jul 24, 2018 9:39 am
Been using it for gigs for a while, typically with gain set around 7/10 and volume similar level for dirty chord work. (I use the other channel for a much cleaner sound for chord work on other songs). We play high energy old school punk so most of the time I'm on the dirty chord channel. I connect to a couple of Celestion greenback 25w speakers using speaker-grade short cables.
When soloing I kick in a clean linear boost to lift the volume. Depending on the amp volume I'm set at, this sometimes causes nasty feedback, I then have to dial the gain back and it compromises the tone I get. I need to fix this. The guitars I use both have wax potted Gibson 498Ts so it's not the usual microphonic feedback you get with some guitars. Standing further away is not an option, in most of the venues we play I am always within a few yards of the amp. I have tried positioning the boost at different points in the chain too.
Is it simply that I need more headroom on the amp, and 30w is just not enough for what I'm trying to do? Opinions gratefully received...
