Possibly. I grew up playing violin and not many kids seemed to have the inclination to intonate. The early years were hard going. It's a lot harder to play a violin in tune if you ask me. If I picked up a violin today it would not be pretty! Anyways, give it a lash, you might jump right into it, or not. Good thing I proof read the autocorrect. Also, every bass I ever bought used needed intonating. Some just to get 7th fret acceptable. Yet I don't hear basses on stage that need the screwdriver, stat! Could be only bedroom players selling basses on Trademe but unlikely. The takeaway is there is a bit of leeway between close enough for jazz to close enough to spot on to spot on.

NZ has a site called Eventfinder. It isn't at all fussy about what gets posted up as an event. Loads of bars put their entire DJ band and jam / open mic sessions on. Assume there's something similar operating in UK. If so, it's likely very searchable by location date and key words. Ime if you are quick on the uptake it's easy to be the only bassist sitting in all night. Always ask someone new if they want bass. The more you do it the more songs you never knew you know without dropping too many clams.

Or a 10ft hard ceiling hard floor combo. Or an acoustic guitar on stage. Best not kick it off with a boomy cab for starters.

Need to find out from OP if this is the case, because it sure looks likely! Once more for the cheap seats, parallel 8+4 = 2.6 in ohm maths. 99.999% of amps out there have parallel outputs. Series would be either 8 + 8 = 16 ohm Or 8 + 4 = 12 ohm. Solid state amp would put out the max volts but achieve relatively little power which means less current and less heating potential. A bit like it's hard to bust your boiler pushing against a brick wall but pushing a car will do it. Again, nearly all amps are parallel out meaning you need a special cable set to get the cabs into series.

A HPF (high pass fiter ) can make the bass control very much more useful.

If it's the Genz neoX it's a bargain and not all that heavy. People do blow them up if they put silly big amps on them and rely on knob positions to tell them what the limit is.

A town near you.

True. Not sure if it's posts or days that gets you the key to the pantry.

My very first, and only bass rig for a very long time, came with a thing of wonder, a heavy 1/4" speaker cable. It is still the only one of those I own! One time the guy I played a lot of open mics with calls me in a panic. ''Can you do the PA for tonight?" Half of his gear got left in another guy's car and he was out of town. So not having had my gear out in a long time I get a mental checklist going for what to bring to get out of his mixer to my stuff and have bass and guitar and vox out from what is accessible in the garage. 'No worries''. Get there and plugging it all in and almost done but I am one 1/4" speaker cable short, AARRRRRG! ''What's the problem'' ''Missing the speaker cable'' ''Oh'', helpfully wanders to the dwindled pile of spare leads which are not speaker leads in any way shape or form. The star of the show has my speaker lead sticking out of his guitar.

I don't imagine a cab would come from factory with 1 and 2 shorted together but someone might have 'improved' it? It still wouldn't require a 1 to 2 speakon but would explain why the cable works only 1 way. Suspect doofus involved.

If you're seeing large excursion you need a highpass filter.

These be in the expensive cabs you didn't want to talk about.

That function is unsupported on my phone browser.

I think the footprint of the BT is a red herring. It's barely bigger than any other 12" cab, only maybe 3'' wider than a 210 with a shelf port sat on its end. You really just want something semi disposable to use on this gig. There is a GK212 500w combo for 540 quid in the classifieds.

When I clicked on your link I got an avalanche of ''special offers'' coming at me as I scrolled down looking for the catalogue. That screamed spam to me and a few others. Maybe you can change the link so it goes straight to basses?

Only thing I can think of is you could be getting a momentary bad ground condition by thwacking a string against a pickup, akin to the pop that can occur with engaging pedals from standby sometimes when they don't maintain the same ground potential as one another.

That is strange. Maybe your idea of gain down is still a boost going into the 2nd pedal. What happens if you bypass the 2nd pedal?

You'll have to explain the problem with £££'s worth of gear on this gig. Eg I have a problem with leaving my good stuff overnight at venues I know to be insecure. As far as worrying about my stuff under supervision goes, I don't allow any beverage storage on top and that takes care of it. It's very hard to knock over two 210s that are ratchet strapped together.

What's the need for the Big Twin if two 210's can get the job done and solve the stage footprint issue?

Sensitivity at 48hz says nothing about power handling at 48hz.
