gub Posted April 13, 2012 Share Posted April 13, 2012 I have a great old antori jazz which i am loving playing its just that the tone knob issue in that it seems i have to turn it all the way down before it takes anything off and turning it up doesnt make any difference past about quater of a turn . any ideas? does it mean i have to get the pot changed or could it be an easy fix?

brensabre79 Posted April 13, 2012 Share Posted April 13, 2012 probably a cheap or wrong type of pot. I find LIN works best for tone, (LOG for volume) have a look out for CTS 10% tolerance (vintage style) pots. they are about £6 online and well worth it. changing the pots is not that hard and not expensive but can make a huge difference... I used to have an Antoria EB-3 copy which was great to play. I miss that bass sometimes. but the electronics were sh*te. Quote Link to comment Share on other sites More sharing options...
brensabre79 Posted April 13, 2012 Share Posted April 13, 2012 you might also want to upgrade the capacitor on the tone pot too. get hold of the 'paper in oil type' for a lovely smooth warm rolloff Quote Link to comment Share on other sites More sharing options...
ahpook Posted April 13, 2012 Share Posted April 13, 2012 if it were me, i'd replace the whole wiring loom, pots and all. then you know it's all ok. Quote Link to comment Share on other sites More sharing options...
icastle Posted April 13, 2012 Share Posted April 13, 2012 Pots either work or they don't - usually due to mechanical failure, resulting in scraping noises as you rotate the control. I'd say that the pot is either the wrong type or value (fault has been the same ever since you've owned the bass) or that the capacitor has failed (fault has appeared recently).

StraightSix Posted April 15, 2012 Share Posted April 15, 2012 This is a cheap upgrade for old electronics: [url="http://www.ebay.co.uk/itm/Jazz-bass-Wiring-Kit-poly-capacitor-Alpha-pots-/130409643934?pt=UK_Guitar_Accessories&hash=item1e5d053f9e"]http://www.ebay.co.uk/itm/Jazz-bass-Wiring-Kit-poly-capacitor-Alpha-pots-/130409643934?pt=UK_Guitar_Accessories&hash=item1e5d053f9e[/url] Quote Link to comment Share on other sites More sharing options...
rmorris Posted April 15, 2012 Share Posted April 15, 2012 alternative view: the effectiveness ( or otherwise) of tone controls in high impedance ( standard passive pickup ) circuits is always an issue due to the electronic parameters involved. Do you really need a high impedance tone control at all or can you better get the tonal variation wanted using amp / preamp / pedal controls ?
