Will you try and troubleshoot the guitar stuff as well?

Multi-tasking...give me a tasty short shot and I'll have your cavity well tidied, copper lined and plugged...annnd your guitar as well...annnd I'll be whistling a little ditty for your pleasure and delectation whilst merrily pressing home the copper...oh, the joy is never ending, never ending, please make it end

I suddenly feel redundant around here

If you want cheap copper adhesive backed tape for lining your cavities, slug tape from bunnings is the go to!

Above PRS obviously.

Mannix...doh, I get it now. Google said,

The 26 pieces are made in Mongolia by unskilled chimpanzees then sent to China for assembly by 8 month old children in kindergartens."

You guys...so nerdy, so very loveably nerdy

Hey, no shit?! Great tip, squire As a coincidence, me and the boss have a trip to Bunnings chalked in for the weekend...at our age we call them date-nights

Well...after this morning's cavity probe, I have this to report:

Gave the jack socket a squirt of DeOxit prior to further probing incase it was a simply contact oxidisation fault. Tested. No change
Stupidly simple guitar to disassemble/reassemble...wow, I love it
Cavity is indeed tight
Visual inspection revealed nothing unusual. Probing commenced. Nothing immediately weird. Further disassembly commenced to enable copper lining
Pots out. Boom...wire from vol pot to tailpiece stud mounting came away from pot despite the large blob of solder supposedly anchoring it there...suspect this may be the culprit. Re-soldered.
(should have reassembled at this point to test hypothesis but continued with cavity lining as I'm a crap methodologist)
Copper screening tape applied and tested for continuity to ground, check.
Reassembly...poo...corner of plastic jack socket mounting disintegrated before reassembly...added to shopping list. 3 screws are holding it together for now.
Test...success! Substantially quieter and as I recall. Still a bit hissy but well within acceptability for a P90 at low amp vol.
Conclusion: Joints...good joints are a must



Tweaked D string pole piece up and B string pole piece down...far better balance across the string set.

Thanks to all concerned for the right-on advice!

Nice one, so the hum wouldn't have been getting quieter when you touched the strings?

Nah...and I didn't pick up on that one. I was more focused on the hum getting louder and quieter when I moved the guitar in relation to the amp. With it parallel to the speakers it was very hummy/buzzy and then it died down a smidge when I turned to point the headstock right to the speakers. EMF, man...spooky shit


Hey, as an aside. Is it rock instrument playing dudes that fetishise the most about their gear? I mean, do the violin crowd swap out their bow horse hair for that combed from the tails of albino unicorns grazing on the plantains grown on the chernozem soils outside a remote hamlet in the Poland? Was just rolling some Mullard, Brimar and Telefunken valves through V2 in the Twin and thought, 'what the fuck am I doing?'

The classical musicians absolutely froth over gear. They don't have much, but the gear they do have they spend insane amount on.

I have a friend who is a professional violin player, playing in NZ, UK and now Australia for a number of years. She thinks that NZD$10,000 on a bow is common in her circles.

Maybe she should try a curtsy?

I’ve found hum can vary depending on what you’re wearing. You’re an antenna after all, and the guitar grounds you. Poly hoody over merino T-shirt creates crazy static, which leads increased noise when you bring your picking hand closer to a pickup (even humbucker, even with full cavity shielding/proper grounding etc).

Super curious - what is this blackface Mesa-esq with voltage Selector?

Loving the double cream too!

The human theremin? Could it be figured out as a new modulation effect control voltage input…

Double cream…yeah, fanks kind sir. They replace a pair of JBL E120s…beautiful sounding in an open back combo but phenomenally heavy for an old codger like me to lift. This mix comes close but lack the ‘expanse’ (twinkly highs, smooth mids and connected bass) of the J‘bells…I’m hoping as they loosen up they’ll get more musical. Enjoying the weight relief though

Amp is a ‘75, Fender SF Twin Reverb. US build for export, hence the voltage selector. Has NFB mod instead of master volume so operates like a non-master black face…power section wide open all the time, gain controlled at channel volume. Sensitive to noisy gats as a result. Can go from hyper clean pedal platform to compressed, ‘touch’ sensitive, growler by winding on more or less negative feedback in the circuit.

Along with a Roland RE501 tape delay (on loan to a mate up north…must visit now as COVID settles down), this rig was my ska(nking) staple. Bit old and OTT for today but has the vibe to my old ears So...it's not a Mesa-fire-breathing-hi-gainer, sorry to disappoint. Hi-gain might be more of a 'rock-steady' or 'sludge-dub' vibe thingy...

Thanks for the interest, brother
