Hello TalkBass, after a light and unfortunate carrying accident my old Hartke 7000 amp has lost a few of its knobs. Actually, the pot shafts broke along with them and I can't seem to find the majority of the ones that fell off. I guess the pots themselves can easily be replaced by any repair shop, however the knobs are the tricky part. I like the look of the original ones, so I'm turning to you for help - Does anyone know where I can find original Hartke knobs (they seem to be the same on quite a few of their amps) or at least something very similar? I live in the UK.
