Works well for a tour, poorly for frequent gigs around your home town.

Turn a regular one inside out? Maruszcyk straps for my basses. Nice padded leather.

When looking for a different sound for a different instrument using a different dial-in technique makes sense.

The ATH M50's are in the same league as Sennheiser HD 25 and Beyerdynamic DT770 pro cans. Fine for your average studio or home practice work, might be ok on stage but aren't high-end. That means they are replaceable so not a bad thing. See if you can borrow a pair to try out!

Some good advice here already! You could try passive sound isolated over ear cans while wearing the IEMs, and make sure the IEMs are not faulty. The less noise you are exposed to the easier it will be to get a soft but clear signal. EBSfreak has a good idea using octave up, maybe add a good EQ to cut disruptive frequencies, like the Mxr 10band, or even a rack unit. Anything that works isn't stupid! I see no downsides to playing live with headphones on. There must be an audiology professor at a university with experience in this sector, maybe you can find one? I know most academic hospitals here in the Netherlands have someone with a passion for music who know about this sort of thing. (Jan de Laat at Leiden UMC or Alex Hoetink at Utrecht UMC for example). Best of luck!

@Lozz196 What clip? @fleabag Ah a Motown fan!

You don't get what I mean, that's fine, says enough. Never mentioned the guy's skill.

How does it read at the 12th fret?

What a D**k. Drummer is the real hero, keeping it tasteful and entertaining while holding a clear rythm. Letting the bass breathe. The other way around when drums gets his moment? Nothing. Bass still hammering for attention. Is the church for his ego?

Morbid Angel in the Vincent/Azagthoth era was massive. Slayer lost their way in the 90s after booting Lombardo. (Absolutely adore Show No Mercy/Live Undead, they only got that intense again on Seasons in the Abyss) HOWEVER Metallica was meh with Dave Mustaine. That split was the best thing to happen to both parties. Faith no More Mosely-Patton different bands, both genious. Funny how none of the vocalist changes really impacted Bolt Thrower's quality. I'll happily put any of their albums on repeat for an evening.

The latter the former you must mean?

Obviously not just one single complaint. Time moves on I guess.

When I was 13 I was listening to Halloween, some Iced Earth, Maiden and Metallica. At some point that year I subscribed to Aardschok magazine and got Slowly We Rot as bonus record. At first I couldn't work out at what speed I had to play it, it was so alien! 😄

Blessed are the Sick and Altars of Madness are landmark albums, significant of the new styles being born out of heavy metal. I think it's great that all the original musicians are able to play their best work from that era, opposed to weird constructions like Entombed AD for instance. I'm sure that when the divide becomes less 'fresh' some classic songs will make it to both their setlists. May take some time though!

I got a pair of Samson SR850 headphones to kick about the place recently. Well pleased! If you can stretch to get the DT990s though, that's a no-brainer!

Lard

Deadbolt is known to play live with multiple bassists. https://en.m.wikipedia.org/wiki/Deadbolt_(band) And I'm thinking Thundercat?

Go full Gene Simmons!

Maybe some FastFret?

I've been to the place (this past spring actually) never knew there was a band named for it!

Which is why all my preamping is done on my pedalboard. The amp is for making loud.

The original Barts J dual coil 5 look good for your wants and needs, shoot them an email and find out what they recommend.

Don't believe him! Believe me! You'll regret it...

What I use to practice at home is a IRig (HD2) into an ipad with amplitube installed. Either use headphones (Sennheiser HD 25 in my case, other options are available) or connect a small amp. I have a Kustom defender 15h amp and cab, not ideal for bass but good enough for home use. However I can recommend the Roland Cube for bass, very nice, tiny, many many options.

I believe the original question was resolved 8 months ago, so it's all moot now. In my experience cheap subs make sound worse rather than better, and one is better served by concentrating on the main thing: the unit that creates most voice and music.
