Talkbass basses for sale has filters for 4 and 5+ strings as well as lefty.
I think the search will find all semi-acoustic electro-acoustic just with searching on acoustic.
There's always the Wanted section but afaik it's still unbumpable, except for moderators.
That's some pretty exotic tapping. I now have precisely no idea what's problematic.
Do over time.
If you play it and report which notes have buzz maybe all will become clear.
Post here used to chuck your stuff on a shelf and send you a letter of demand on behalf of Customs, all for free. Then the volumes got out of control and they realised what a racket they had been missing out on. Booh.
I received a custom bass from the luthier in its case, secured with liberal duct tape. He was adamant it was the best way, as to encourage couriers to take care.
I used to run a big board. To get around the low end loss I split the signal after the octave, high and low and put the highs through the other fx before blending back.
Prunes and Custard figured highly in faux synth stuff. Also octave fuzz envelope combinations.
0.3mm or 3mm?
0.3mm is pretty much flatter than a flat thing! Then 2.5mm of action is just a bit ambitious. Making it flatter still won't help.
If 3mm of relief then 2.5mm of action does not compute.
