Yup, I must have got my eyes crossed looking at it on my phone! For the continued mystified: Placing a straight edge on the graph at 0dB& 40hz, parallel to the gist of the intial curve, hits 10hz down at -36dB = 18dB per octave. [10¹ hz to 40hz is 2 octaves]

I did wonder about that having never heard of one but that's what the graph says so caveat emptor.

Unless your hearing is stuffed, and even then what you hear is what you hear. Presumably you are a beginner? New around here anyway so welcome to the rabbit hole that is finding the ultimate rig to end all rigs quest. Back out now quietly while you still can or the g.a.s will get you. Still here? Be aware that the sound of a 30w practice amp is a whole different ballgame to a rock'n'roll stage amp, although in some circles they are one and the same.

If it had a DI folks would complain it didn't have any overdrive to complete the straight to desk package.

Only if the amp can't drive the 8 ohm version fully. That's exceeding rare and I really doubt it applies to OP's 800w amp. If you're talking about increasing the number of speakers then that's different. We weren't talking about that.

It's not readily apparent whether your guitar playing is rubbish or the riff is really odd. One little passing lick in the middle is very Nirvana.

Looking at it again you could say the response measured pretty flat to 40hz and call that 0dB. Below 30hz it's on about a 8dB / octave slope and the -3dB point comes in around about 28hz.

The zero dB level is plotted a fair bit more than 3dB lower than it should be ie the scale needs a vertical shunt to slice through the flat part at 0dB making the fall off represent the filter.

Aka burning up the 4 ohm version chasing your tail.

So long as your amp can do 400 clean watts into 8 ohms it wouldn't make a blind bit of difference.

Same drummer used to have a bad habit of getting the count off way wrong. Sometimes I had to wave it all off with a HELL NO!! One time he slipped it in at DOUBLE time and the fricken showoff trumpet players played on so the poor singer had to improvise the Chipmunks version. That was the last straw and next rehearsal he showed up with a tablet metronome doofer with the set all programmed in.

As frequency approaches 0, so you approach Direct Current.

Rules is rules. Get over it, ship the stuff and pay the tax. No need to bring the politics into any of it.

Bet your bottom dollar they do.

Sure it's separable, by simply not stirring it up! The discussion is onne of many about making ones way in the new world of a customs border between the UK and the non UK. It's totally not difficult to avoid bringing in the political history that lead to the new situation.

Well said.

Drummer recently complained of the ''dirty looks'' I give him when he messes up. I explained I am only looking for visual cues ( for me to determine the path of least resistance to reestablishing time with the band ) I can't help it if my panicking bass face looks a bit dirty and it's probably best the audience don't see it!

It's ALL about the mix. Awhile back there was a collection of isolated Macca Beatles bass tracks floating around the 'net. Holy cow what a terrible collection of bass tones! Quite an education.

Yes. ( We could get into a big discussion about 200w being 200w but most of it would go over your head. )

Series 6 is late 80's / early 90's. It's very good for surprising kids that 200w can rattle their fillings.

A few years ago I got fed up with a particular 1 bar drum fill always being rushed and causing a giant hiccup. I decided to play only 1 and 3 over the fill and resume the walk on tempo. I only had to do that a couple or three times before the showoff fill got simplified to something he could keep his own time on.

Tie it to your ankle with a bungy and scone the guitarist's shins with it when he turns up.

True. It's also the first skill you want your drummer to have mastered! The adage goes ''It takes a very good drummer to be better than no drummer''. I play with a Russian Dragon. He is completely reliant on me to keep things steady.

Everyone needs to stop conflating Rumble Filter with HPF. Same same DIFFERENT.

The problem with capable adjustable HPF onboard amps is in the selling. The average bassist isn't well informed so when asking what the HPF knob does the sales guy says 'it cuts off low end' and the next words out of the shopper are 'show me something else'. Iirc the Thumpinator is -3dB at 30hz and a 12dB / octave slope, higher than fixed filters on amps but too low for what most HPF users are after. Ymmv.
