The usual situation runs like this. One powerful amp. One cabinet. The rig only gets so loud before the amp overdrives the cab. At that point you are all out of headroom. If that's only just enough to be heard in a loud band it's not at all dynamic unless everyone respects that limit and adjusts themselves down. More usually the bass player adds another cabinet. Now if the amp is powerful enough to drive both cabinets to their limit you have the full +6dB experience in the low end. Going from zero headroom to 6dB of headroom is quite fun, especially if the band becomes responsive to bass dynamics.

A helmet with horns to complete the look.

This is flat out wrong. Never connect two amplifiers to one cabinet. I dunno what's up with that graphic. I have a Mesa tube amp with 8 ohm and 4 ohm outputs labelled like that. The 4 ohm ones are parallel to connect 4 ohm worth of two 8 ohm cabs. Dollars to donuts OP amp is a bog standard solid state MAG with parallel outputs. Connect two 8 ohm cabs however you fancy. 4 ohms job done. Egads what a mess.

It's perfectly fine to use two cables from your amp to two 8 ohm cabinets! Cabs put a load on the amplifier via cables. You are very confused in your questions.

For transparent aside from squished you can't beat the old Trace SMX pedal. One knob for the lows and one for the highs. If you get a wild hair on you can see-saw the EQ with the balance control, or leave it in the middle and it's transparent.

If it popped off I expect it can be popped back on. I would bodge it up with a spot of blutac to encourage it to stay put but no guarantee it wouldn't get off again.

Heavily skewed to the portable and economical end of the options is the good old cardboard + duct tape drop cover. Good for keeping out the rain and scuff protection while not adding a lot weight, so less likely for it to take an unaided trip down the stairs.

You're going to be fine.

Much to the consternation of musically educated folks.

Melodies and lyrics contain copyright. Chord progressions do not.

Make sure you are in tune. I find myself recalling the hook chorus in order to remember the rest of it. I find using crib sheets makes me reliant on them. Better to remember if you can.

What's the motivation?

I don't know if that would get you the amp alone here.

The Tweeter and the Monkey Man number works great but they really should have put Dillon on a low part on Handle Me With Care. Over here the radio played HMWC on a fairly high rotation for a little while and that was pretty much it until Classic Hits brought it on.

If the tuner was upstream of the amp and tuner is testing ok then the problem is in the bass.

Just noticed this. Definitely your bass output jack is wonky. Or you had a bunch of dud leads.

I should read more carefully...

I am retro! Small company obviously unwilling to expand its workforce instead cuts off orders to maintain sanity. 4 years worth of orders on the books ought to give plenty of opportunity to take on an apprentice or two.

At a guesstimate that's 5 years worth of all my pocket money! I can understand a professional bassist wanting to get in on 'the best bass ever' but the rest must be wannabe dentists?

No pic no, no new rig!

Who is buying all the vinyl they are selling these days? My nomination for future appreciated currently sunk with hardly a trace and barely appreciated in the first place album is The Travelling Wilburys. One hit 'single' got airplay for awhile, 'Handle Me With Care', then zippity nada except the occasional play on Classic Hits of late.
