Hello guys, First time Post here. My bass has been playing up on me for a long time now. All the knobs give a crackling sound when your turning them and hiss and pop. As well as this the sound completely cuts out now sometimes as well, with the resolution being a hefty whack on the back of the body! All i can tell is that there is only one volume knob from what I can tell. Im guessing the other 3 just are tone knobs of some kind. My worry is that its already been Frankensteined! No readable info on the pots! Wiring looks a bit dodgy! The bridge and saddles and machine heads are oxidised so it was obviously Stored somewhere damp at some point! I bought this bass with a hard case for 120euro as my first to learn on, and its still my only bass. I love the action and the feel of it and would love to get it 100%! It's a 5 string Active Dean Bass. No model number anywhere on the bass! I think its a PJ bass!? I use it to play slap bass mostly. Les Claypool Would be one of my biggest influences. Now.... Ill attach photos of my bass, I cant figure out what parts I need as there are just too many options! I have no idea if I should go passive instead for slapbass? Either way it needs gutted and sorted! Any help would be most greatly appreciated. I am not used to working with basses but I am used to working with soldering irons etc so I should be able to handle this project! I need help to know what parts to buy. I would be willing to replace the pick-ups and all if I was told it was worth it! Is the oxidation on the bridge be affecting the sound badly? There is literally no good shop anywhere near me at all here in Donegal.
