Wal, that looks like a very bad Aria to live in ...

That barrel-vaulted ceiling is focussing audio down to head height. Great for sermons, not so good for anything else. I'd fly some thick absorbers around the height of the cross rails and put some 50mm panels, stood off the wall by 50mm, on the side walls - particularly at the speaker locations.

We shouldn't really be using 1/4" jacks for amps over 100W. Neutrik jacks are only rated for 50V or less and the sockets are rated at 3A. 100W into 8R = 3.5A 28V 100W into 16R = 2.5A 40V 150W into 8R = 4.3A 35V 150W into 16R = 3A 49V 200W into 8R = 5A 40V 200W into 16R = 3.5A 56V So it's easy to exceed volts or current ratings. They may/will still work but they're not really rated for it. Speakons are, in every way, superior. 30A per contact 240V max

First it's the room - usually a proper vocal booth which is pretty dead, and keeps out unwanted sound. This can be approximated with hanging duvets making a booth into a corner, but anything with early reflections will sound like your bathroom... Next is mic choice and position. I've used MKH416, Neumann U87, EV RE20, Rode NT1, SM7, Coles ribbons and others. Some voices need a different mic - Mariella Frostrup had a very gravelly voice... never had to de-ess with the right mic choice. Mic position was usually 45 degrees front/above around arm's length. Closer for cosey narration. Some minor EQ - mostly high pass, and mild compression for most stuff, heavy for commercial radio. A felt top lectern for scripts and talkback or cue lights A voice artist also helped lots - Emma Freud and Lesley Judd were both 'one take wonders' - company COs and similar with no mic experience could be a pain.

Yes, a good office type chair, without arms, is great for both practice and PC/DAW work. I splashed out on an Orangebox Eva chair 'cos Covid / WFH and it's perfect .

Swamp Ash? Made from ash and stored in a swamp... 😉

Those are inputs.

Get a small bag of lock-washers. Switchcraft jacks and CTS pots use washers with 3/8" (9.5mm ish) internal diameter. Lock Washer (Star) for 3/8 Pots and Jacks (pack of 8) Lock Washer For 3/8 Pots and Jacks [STAR(B)] - £2.20 : Axecaster Barrel jacks need 12mm internal diameter Import (metric) jacks and pots are usually smaller. Hosco do wee baggies in all the common sizes,imperial and metric...

You're just after the shown dock bit? You can still charge the transmitter directly with a micro USB cable?

Hmmmm.... If none of the wiring has come adrift it sounds like a pickup problem. Do you have a Multimeter or a soldering iron? With a multimeter measure the resistance across the two outer volume pot lugs - should be around 8K Ohms ish... If it measures around 250K Ohms then the pickup is open circuit. Desolder the pickup lead from the vol pot outer lug and measure the pickup directly - again should be around 8-10K Ohms If no multimeter, desolder both pickup leads at the vol pot and croc lead them to your guitar cable/amp input - if no signal then pickup is open circuit. If you are feeling brave unscrew the pickup (both halves) and pop the covers off. Have a good look at where the cables solder onto the very fine pickup windings - sometimes these break.

Suggestion 2 a strip of ally lager can, superglued into the speaker hole...

How are the frets, wear wise - any big dips? Get the fret rocker on it - are there a few high frets - a local level may be all that's needed. If there is meat left on the frets a level, crown, polish is not a big job (takes me an hour and a half, with two mugs of tea)...

Sounds like the ground side is not grounded somewhere... Does it have a ground wire between the pots or does it use the plate for grounding ? - tighten all three pots and the jack onto the plate. Get a croc lead and short the jack ground to a vol pot ground - does that pot now go to zero? Jazz Bass WIRING 01D.pdf

Hmmm... weird one... You've tried all the obvious so it must be something else. Things to try; You could have a weak pickup magnet on the E string (you've changed the pickup so probably not this) - tap all the pole pieces with a (steel) allen key - do they all make a similar bang and are they all similarly 'sticky'? Nut. Have a good look at the nut slot for the E string - is the slot cut right and is there a tiny clearance (try a sheet of paper) over the first fret when string is fretted at fret 3? Also check the E bridge saddle. Room. Are all your listening test being done in the position in the same room? Room dimension s can really effect the low end - my living room has a big peak around A which sounds much louder than it really is. Try with another cable, direct to the amp - there can be odd effects if the cable's conductive plastic layer is not stripped back correctly. (clutching at straws here). What bass, what pickup, what strings? It is possible to wire a PBass or stacked jazz pickup out of phase which makes for a weird response.

Get some bigger Genelecs.

Standard M5 Nylon 66 washer is 5.3mm ID 9.5mm OD 1mm thick - so basically correct https://www.flexibleandfasteners.co.uk/Shop/m5-nylon-metric-plastic-washers/ https://www.amazon.co.uk/M5-Nylon-Washer-Washers-Natural/dp/B006XURJH8 These are nearer M5 x 7.5mm, also nylon... https://www.amazon.co.uk/sourcing-map-Nylon-Washers-Screw/dp/B07NRYZG81 https://www.ebay.co.uk/itm/362586035318

Anyone know what size (ID and OD) they need to be? M4? nylon and PTFE washers are available for pennies...

Rubber O rings might work ?

Possibly a bad solder joint on the neck pickup / pot ?

If Deoxit doesn't fix it then replace the pots.
