I've also come across that prob (not same cab).
Lay cab on back.
Take screws out grill. Remove grill. Remove screws/bolts from top cab & lay on top of cab. Look inside with torch & see if anything is touching cone.
Fix if so.
Put back together.

I subbed for a 6 piece at a hotel NY gig a few years ago & got £150 in my pocket. Reckon the charged £1000. I knew a band from the Notts area that used to charge £2500 and overnight room. And usually got it.

*FINALLY* got to use my converted Ashdown 1x12 at a reasonable volume at a jam last night. Very satisfactory. Playing a Thomann Harley Benson Fan fret 5 string into a MiBass 550 with all EQ switched off except the 'Shape' button. Added a little bass & mids via the 18 volt pre in the bass.
Tone was deep, lush with that edge provided by well-defined mids. Absolutely what I was looking for in this mini-rig. Well worth doing.
Many thanks to RichardH for doing the crossover and Phil Starr et al for all the groundwork.

Point is, if you are doing XLR to jack, it needs to be a stereo jack as the balanced signal has 2 live feeds, one positive to tip (usually) and one negative to ring (usually). So running to mono removes the balance.

On my Overwater, I need to have a jack in the main output simply to turn on the pre-amp. This enables the XLR & I can plug straight into the board using that. Take out the jack & no signal from the XLR. XLR to Mono is somewhat defeating the purpose, I think.

I currently have EB Cobalts on all 4 of my basses. Quite pliable, defo less tension than Fender and LaBella flats. However a lot of treble on tap. I love them. Depends what tone you like.

If you like *slightly* less gain, try a 5751 instead of the 12AT7 also said by some to give the best tone of all those types - personal preference obviously.

Ernie Ball cobalts are my current weapons of choice on both fretted and fretless. They sound almost like nickel round wounds to me (just a little less top end).

He's miming though. Did he use them for real?

He certainly did. I saw him with the Graham Bond Organisation in 1964(?) and he was playing one then as well as an upright.

AFAICS none of those circuits include the choke which IMO is an essential part of the Gibson Varitone sound. That's the hard bit to do as it seems for the best results you still need to wind your own.

The link I included has a bit about including an inductor as a choke, further down the page. I ordered a group of inductors off ebay & used the one which seemed to me to work best.
