Nowhere. It's the same old heft with added lightness.

Most amps will do hifi = what goes in comes out louder. You go in the fx return. Whether you like it or not is then up to you. GK far from uncoloured but can be EQ'd flat. If you are in the habit of turning down the lows and the highs and boosting the low and high mids with the contour off then you are potentially liking hifi.

Quilter 800 series are hifi unless you raise the input gain past a certain point. You can get loud and stay hifi by only raising the master output. EQ knobs noon is no EQ.

Sounds like you were ambushed into accompanying the leftover muppets who hadn't had a go yet. You need to develop some 'authority' about your output that better players will tag you to play with them more often. That's basically how I progressed while not owning a stage amp until I got offered a gig and had to go buy one smartly.

I hope the drum scaffold gets moved as a unit into a van of the appropriate volume. Suspect not and they all get put into cases and it all has to be tetrised in a particular sequence. I used to play with a demon drummer who could have all his gear set to move before I had unplugged my cabinet. Freakish ability to get gone.

Had one. It worked as advertised but the accompaniment was not in the brochure. Too noisy for me.

The harm can come plugging into the cab with a 1/4" lead and briefly shorting the amp across the tip and shaft, much the same as dragging your lead out of your instrument with the gain up puts one across the preamp. POP. Dead short plus solid state for too long is very bad business.

What's a switching preamp without its foot switch? Mere completion of package no different to buying a bridge for a bass you got last year missing a bridge.

Can still take your head off. How small? I used to play with a guy that had the Orange Tiny Terror on the low setting into a 212. 5w or 7w I forget, less than 10w! He was quite loud enough for a bar room just by himself. I used a 210 and drummer had dynamics for Africa. We would get a better idea of how much of a racket you guys are intending if you tell what the bass rig is.

Would normally have a proper PA these days if a vocal PA would not cover it. You could add a sub to bump up the kick and your regular amps will suffice for a party of 300. Don't forget your earplugs. You don't need hifi most of the time. A racket is what most people want. A drummer blazing away with a healthy right foot is freakin' loud in any enclosed space you would call a bar with a band as opposed to an entertainment venue with a bar. By the time you add vocals over that, and some bass and guitars that are not determined to be the loudest thing by 10dB, you are not short of volume. Fidelity not great, but to get into the hifi realm you need the drummer to wind it all right back and everyone to play weenie amps on stands pointed at their own heads, all mic'd up, or go IEM. It only takes one deaf prick needing to play loud on stage to cascade into bedlam. Or a drummer that can't do 'energetic' without smashing stuff. Where is your mileage at?

You might want to try picking up a V4 before getting too invested in that idea.

Looks like a chick on the bass in the vid, named Hagar????

And here's me with pedal board top down illumination so my lousy night vision can make out what the hell is going on down there.

There is something that does exactly what you ask. Sorry I can't recall the name. On a different tack. The sfx Red Dragon pretty much leaves your lows alone while doing a nice overdrive. You might have to make a special order as almost nobody ever sells theirs. Beats me why it got discontinued. There's demos on youtube.

It's why if you look up the phone book for an electrician you won't find any named Murphy.

I'd be very surprised if you haven't just volunteered and been appointed convenor of your very own bass bash. Have at it. They usually get arranged several months ahead by my casual observation.

15's have such poor dispersion characteristics. Not nearly as bad as 410 in a square box, with the glorious exception of Barefaced 410 etc.

I think you may have over interpreted "manhandled"

No need to get burned again. Fix the faulty wiring for starters then do the homework on the actual battery state that could let you down. And then you can stop buying the cheapo batteries for each gig.

At 50/50 blend, or somewhere thereabouts, does the hum go away?

Start with it at minimum every time until you learn where it needs to be. Then start with it at the minimum every time because if it ever accidentally got bumped up to 20v in transit it's going to do damage.

A hum that goes away when you ground the bass sounds like the first pedal and the basses have different grounds. No ground on your basses?

Hell wasteful to be junking barely used batteries like that, or do you use rechargeable ones? The hungriest active I had would do a dozen gigs on a battery. That hungry bass gave up with juice left and the other could keep that battery for months. I am sure you could save a packet and whole lot of waste if you put in some research on what volts it really needs to maintain sound. I got a 4 pack of cheapie 3v buttons for scales. Expensive enough. Checked the 1st one. 2.5 v out of the packet. No more of those!

Two stories from the stables of AgedHorse come to mind that bury class distinction. When he was a more junior engineer he got fired for fooling all the audiophiles that they were blind auditioning a bunch of amps when it was the same amp the whole time. Later he was involved in developing the GenzBenz class D lined up to replace the class A/B. Iirc it was the same old preamp with both amp sections. Nobody could tell which was which no matter how hard they tried. Some amps have more heft than others but it's not the class of the amp doing the hefting.
