uk_lefty Posted May 22, 2018 Share Posted May 22, 2018 Help!! I was trying to change knobs on my jazz... Removed the chrome ones that have been on for maybe six years and the rubber/ plastic inner has stayed firmly on the pot. I have given it a firm pull but don't want to tug too hard in case I break something... Photo to illustrate. Please help!! Quote Link to comment Share on other sites More sharing options...
BassBus Posted May 22, 2018 Share Posted May 22, 2018 Is that an Allen screw on the side of the black bits? Quote Link to comment Share on other sites More sharing options...
uk_lefty Posted May 22, 2018 Author Share Posted May 22, 2018 No, it's the indentation from where the chrome knob Allen screwed in Quote Link to comment Share on other sites More sharing options...
gary mac Posted May 22, 2018 Share Posted May 22, 2018 A small screw driver placed in the gap between the sleeve and the pot, then gently lever it up. Quote Link to comment Share on other sites More sharing options...
mybass Posted May 22, 2018 Share Posted May 22, 2018 Grip with pliers lengthways down the shaft enough to grip and start moving the rubber and pull upwards. If not then use a stanley or other knife to cut away the rubber. Two screwdrivers, one either side and twist them to start the rubber moving up the shaft. 1 Quote Link to comment Share on other sites More sharing options...
KiOgon Posted May 22, 2018 Share Posted May 22, 2018 The recommended approach is to position a piece of cord or edge of a cloth under the edge of the knob, (or the remaining insert), then pull the string/cloth upwards. Don't punch yourself in the face when it goes! 1 1 Quote Link to comment Share on other sites More sharing options...

uk_lefty Posted May 22, 2018 Author Share Posted May 22, 2018 I got them off using a screwdriver for leverage... Now I don't have an allen key of the correct size for the Fender jazz knobs I bought!! Oh well Quote Link to comment Share on other sites More sharing options...

uk_lefty Posted May 26, 2018 Author Share Posted May 26, 2018 Ok so can we get past all the "it just came off in my hand" etc etc but when I went to put on the new jazz bass knobs (fender authentic ones) I could only screw on the little tone knob (great nickname for a sound engineer), not the big volume knobs (great nicknames for guitarists). Seems the Allen key either didn't fit or something more suspect going on? Needless to say my big nobs won't be on display at tomorrow's gig Quote Link to comment Share on other sites More sharing options...
KiOgon Posted May 26, 2018 Share Posted May 26, 2018 You might well find the bores not finished properly - especialy around the hole where the grub screw pokes through. I always twiddle a 1/4" reamer around the insides, making sure the screw is out of the way first, then they slide straight on.
