I have bought a bruce thomas profile bass. It feels great to play and sounds awesome at practice (low volume) but at gig volume the sound seems to intermittently drop out. it might be one note from a riff but ca happen several times in a song. It isn't a particular string/fret and it happens with pick and finger style. It doesn't happen at all with my jazz bass everything else in the set up being the same ie amp ab cables etc so must be the guitar. I love the tone and want to gigit regularly but can't as it s. Has a one experienced anything similar?
