Cheers guys, some helpful opinions and pointers.
im not after adding harmonies via a pedal, I think that has train wreck written all over it, but the tips to fatten things up, fill out the sound, are good. Also get the compression/feedback point too. Hadn’t considered that.
we don’t use IEMs but I always wore earplugs and found they created a bit of “natural monitoring” in that I could hear myself sing.
I think what I’m hearing is that less is more, get the eq right, and (try to) sing in tune...
