The pair of 2x10s as vertical 4x10 is a a really good configuration!

Why would you even think about trying o play a gig without a speaker cabinet? This would be akin to trying to race a car without tyres!!

Another point is that the 4Ω cabinet will draw twice the power of the 8Ω box. That could be more than the speakers can safely handle..

I wonder how many fires have been started by such cavalier thinking!! What happens in Europe does not comply with the UK's electrical code!

You could ask the expert Paging @agedhorse

If the amp has an Effects Loop did you try linking the send and return with a short signal cable to see if that's what is causing your woes?

If you go with feet that screw on make darn sure that the screws don't protrude too far into the chassis and contact the amp's PCB.

What do you do if all three bands get booked at the same time?

In my mind, take any manufacturer on the planet and compare user comments and you'll find that some folk love them whilst others dislike them intensely. Often being stuck with the gear because of financial difficulties., For myself I too couldn't abide the yellow comes. I want to be the centre of attraction on stage and not my amplifier.

I have played through a plethora of Ampeg amplifiers over my career. I wasn't until I bought my own B15NF that I really appreciated what a great bass amplifier it is. that Tamla Motown sound all day long! I'd never try to gig the amp due to its weight and I'm just getting older!: Moan.

How can you design and build a speaker cabinet without choosing the drivers first?? It's like putting the cart before the horse!

I know but it IS something that must be considered when connecting speaker cabinets to an amplifier..

You also have to consider the total load presented to the amplifier. Four and eight ohms in parallel. equates to 2..67 ohms . If the SS amp can't drive that impedance the amp dies..

Because the Fender Bassman is a terrible amplifier for an electric bass!

I really feel that the Octal 6SL7 double triode tubes have a special Mojo all of their own.

For me at the very top would be the Ampeg B15 series. My B15NF is a delight to play through.

The actual position on the box of the port is not important. My rear ported Acme B2 2x10 three way cabinets work very well stacked as a vertical 4x10. it's my standard configuration.

Standard thing to try if the amp has an Effects Loop is to connect the Send and Return with a signal cable to bypass the normalizing contacts on these sockets. They are prone to oxidation especially if little used.

Any amp will sound it's best when put through a superior speaker system like an Acme. Andy does make good stuff. I have four B2 models each at 4Ω. Enjoy!

I've always found that the best stand for a speaker cabinet is an identical one underneath it!!

Back in the day before the thing ws stolen from the 21 Club in Liverpool, I owned a Gibson EB0F with a built in fuzz effect. It was awfull and completely unusable.

There are far better amps available these days to bass players than an SVT VR.

Even though the poor 15 was in danger throughout the gig!

There, that's the ticket!!!

That is an over simplification. Tube amps give a pleasing distortion when pushed too far. If a cabinet is rated for 750W you need at least that much to make it 'sing'.
