CC1 Posted December 19, 2020 Report Share Posted December 19, 2020 I noticed my new (and first) build actually has a slight issue when playing. The slightest pressure on the jack cuts the signal completely. So I took it apart, and whipped out the multimeter Set to 200O or just the signal beep, I got the following results (Key: Red: Hot / Black: Jack Ground / Orange: Nut / Dark Green: Jack Shell / Pink: Jack Ground Tip / Light Green: Tone Pot shell / Purple: Shielding / Blue: Val Pot shell ) Dark Green -> Purple/Blue/Light Green : Good Pink (jack Ground tip) -> Purple/Blue/Light Green : Good Black -> Pink/Dark Green/Light Green/Purple/Blue : Good - BUT, the slightest pressure on the jack and it cuts out There is a very small amount of wiggle of the cable when inside the jack. The nut is quite firm but I think that mechanically it is mostly pulling the Jack tight in the body - I don't think it's compressing the Jack socket itself. I've used a pedal connector here, but can confirm that same wiggle and the same issue with different cables, which all work fine in other instruments (where there is no wiggle at all) and have all been themselves tested. There is no nut on the outside to tighten either: Question: Is this just a bad jack (it was generic part, ordered from here: https://www.ebay.co.uk/itm/Output-Mono-1-4-Barrel-Jack-Plug-Brass-Socket-Long-Fits-Bass-Electric-Guitar/264737490450?ssPageName=STRK%3AMEBIDX%3AIT&var=564556512021&_trksid=p2057872.m2749.l2649 ), or have I not grounded this properly in some way ( I know virtually nothing about electronics ) If it is the Jack, is there anything I can do or try - or do I need to scrap it and try a new one?
