I loved the c-bomb in my 73 lp custom
sounded a bit dark, and more compressed than any other bkp I had, but in a good way
it actually pushed my amps harder, so it delivered more sustain than all the other bkp bridge models I had in the same guitar (riff raff, a-bomb, holy diver, black dog, aftermath, cold sweat)
it isn't really my kind of pup, but it sounded amazing with the stock 84 jcm 800 2203 I had
made that amp sound huge
based on your complaints, I'm not sure what yo recommend here
tighter sounding models with triple magnets, like the painkiller and aftermath, wil make your mistakes even more apparent
