Spoke with Loud today - very gracious - although a little concerned that the issues were so similar with both heads - as was I. I had actually purchased a new speaker cable because of concerns on the first head going.....and gigged with it A LOT. the other question was in regard to the cab I used - mostly the Avatar SB112, and also the Schroeder mini 12. both are 4 ohm - good cabs. My instrument cables are all good gig-worthy Peavey, Monster, Lava, similar......and the instruments all seem to work and play well with others.........
Fingers crossed - they are sending out a new one to me, and I send the one I have in.
not sure what I am going to do at this point.
I can't ask for better support from Loud on this - and want to openly recognize that as quick as I did the issue with the amp.
its just the trust aspect on the equipment that remains.......
