Phil Lynott. 😊
And Dave Brock, Jamie Cullum, Marcel Dadi, Dimebag Darrell, Fred Durst, Isaac Hayes, John Hiatt, Ralf Hütter, Robert Plant, @Dad3353, ...
Without forgetting Emily Brontë and H.P. Lovecraft, who were not musicians, just in case... 😉
Indeed these TRB-P's are just amazing basses, sadly on the heavy side.
That said, not everybody has a bad back. 😉
It will sell very quickly as they are sought after, for some reason. And it's also a really beautiful one !
Wrap (one layer) some very fine grit sandpaper paper around each different string and use it as a perfect file. Go slowly.
It's a very old trick used by so many players.
As we are at it, be structured, organised and consistent, always using the same pattern for demoing, like the exact same riff played dry and wet. Play fingerstyle (no f*cking useless slap). And if you use different basses, please use the same strings and in the same situation with the same pickup(s) settings. Ideally quite similar basses (not a full maple neck bolt-on compared to a neck though ash neck with wenge fingerboard, for instance) with same setup.
Follow @Lozz196 idea with a standard jazz and a standard precision as we all know how they sound.
Start with a dry flat setting riff (and show the settings onscreen) and repeat it with the wet settings (avoid extreme settings that are really useless).
There are already so many totally useless demos on the web, don't add some... 😉
