I'd go with a string of colourful LEDs, add to the show and only the actually blind can claim to have missed them. Drape over the monitors or guirlande from the micstands?

Hot-glue a sansamp to the gss (baby) sumo. Done.

9v or 18v has very little to do with how hot the output signal is. I've had passive basses with a hotter output than any of my stingrays. A higher voltage pre could theoretically give a more dynamic signal, if providing higher peaks and a lower noise floor.

The pickups are in a different position. Perhaps a three band Stingray is more what you're after.

This sounds like a job I'd have a local luthier take a look at before getting wild with tools myself.

As bass player and lead singer this would put me in a awkward position

It would also solve the sound pressure attenuation. Making them not protect your hearing.

They're there, their.

Except those have no damping rating and you'd be exposing yourself to unknown levels of sound pressure.

"hand made chassis" a smith is hammering the casing out by hand? 2x1500watt at 8Ohm, why not call it a 5000watt amp then if that's what it runs at 4Ohm? The marketing lingo throwing up dust clouds. This all sounds like Bugera trickery to me. Bullhead? I think what comes out the other end of the bull.

Oh I was under the assumption that they were passive open louvres that close when a high energy sound wave hit. I have zero hunting experience.

If there are they're likely going to be very expensive. That's a lot of challenges to overcome. Sound quality and or comfort will probably suffer from having to decouple good built-in microphones from the damping shell.

There's also Bluetooth ones I see, not sure how they are on lag. About €70.

Again easy to solve with a mic in the room and a small mixer.

Our drummer is quite pleased with the Vic Firths. Those alpines look fairly compact, maybe too small for old man ears. Interested in your findings! There's also a lot of over-ear protection available for the shooting/hunting stuff. No telling how they affect music quality. "that wouldn't work for me as we don't mic up the drums or mic/DI the bass)." One overhead mic in the room would do the trick, across from the drummer not over their cymbals.

As is blues. If your chair has four legs then everything with four legs is a chair? Metal is metal, tea is tea. Tomato ketchup is technically a smoothie.

I said that got close, referring to the image posted. It also gets a lot wrong. Pantera is groove metal, Motley crue is hair metal or glam, etc etc. They're as different as disco and funk.

Whatever makes you happy. Wrong and happy.

I would happily argue the labels of many of these bands at length, but this looks fairly accurate. @Barking Spiders immediately at the start.

If by 'rock music' you mean anything with a guitar, ok. But it isn't. Metal is not rock. Stoner, Sludge, Doom and Hardcore are variants of Metal. (there's also hardcore House which is electronic dance music)
