^ As well as the distance from nut to peg plus string thru body or even a trapeze tail...

Get Back! - The Wiggles...

1st thing would be to remove the blend pot and see if thats the issue with a multi meter.. and if so replace with another CTS or Bourns pot... maybe Mouser?

^ Good Darts...

(Is)Lamb lies down on broadway - Genesis

Post a pic of the headstock and tuning pegs... Number of turns round the pegs, and are they defo short scale strings with a thin bit around the peg, and not long scale strings cut down, Remember when restringing... turn the winder, dont wrap the string, as you introduce a twist along the strings length...

Sky Arts... Hawkwind Stonehenge 1984 01:20 - 04:00 It's also on catch up...

If ya havent gone for the pups yet... £33... https://www.dv247.com/en_GB/GBP/Roswell-Pickups-RKB-N-CR-Bass-Pickup-Neck-Chrome/art-BAS0010636-000

Clear the patches on a Zoom B1on / Four... Build a patch or two... or three per tune, with ToneLib, and name it... plus a couple of Defaults... Store patches on a PC... Load ya Zoom with the patches needed for the gig and order them... Loads of Bays and Patches so you could double-up just in case. ToneLib also have an Android App so you can do it from a phone for last min changes. Tuner and Headphone Out a Bonus! Maybe ya Boss can do similar...

These are days - 10,000 Maniacs... Double Points?

@Duarte your previous pic of that P was the insperation for the slanty pups on my J... you bad man 😉 And as for the P.. I like it simple...

Give the strings a wipe with isoprop rubbing alcohol... or one of those Glasses Wipes... and take a hand (beer) towel...

0000 wire wool... dipped in isoprop or lighter fuel... going lightly with the grain... I'd stick the body in a carrier bag, or tape over pickups... and sandwich bag over the headstock... taped closed, to stop the wire wool dust.

Yep one Bass... One for each day of the week!.. {2x Ibby GSR200, Ibby SR600, Harley Benton HBO Acoustic, Custom P Bitsa, Custom J 'PJ' Bitsa. Custom Rickenfaker}

I had the body custom made...

Can i join in... even with a Split P?

^ Did Michael Jackson by the rights to that one? - So he might know... Then again he 'prolly had things to hide between him and Bubbles...

What Brand?.. I've only ever used Adagio and Olympia Flats, (which i think are the same) 45-100... Described as Standard Tension... maybe a little higher than a 45-105 set. Stick em on... might need to back of the truss rod a smidge. Welcome to the Smooth Side...

On Parole - Motörhead

So with a bit of a truss rod tweak a few hours after re-assembley all seems OK... Only checked it out thru a Zoom B1On in SVT Amp/Cab SIM... Sounds as warm as the weather! Maple Neck and a bit of the J added to the P makes for a bit more lively sound than the P Bitsa with a Rosewood Fretboard and a Pickup out of an SX? (thanks to @Rumple) not sure how the SX Pickup rates, or if Ceramic compare to the Alnico Magnets of the Kent Armstrongs etc... Quite unique looking, and sounding good for £200ish... although I wasted 6 Months and another £50ish on Primer, Paint 'n Sanding Paper! - Oh well Live 'n Learn... Spose if the Dip came out OK it would of been worth it!

Lock in with the rhythm gtr and keep it simple 'holding notes' bigger dynamic difference
