I ordered mine March '22. Received November '23, so a good 20 months.

Z.- it wasn't the thickness of the string, it was the tonality. The fundamental and the overtones just weren't as pronounced as the DBR 7th string. A lot goes into picking the right gauge with tapping strings. The upright (when I used to play) was not a problem for me. I was an animal. I broke strings when I switched to fretless electric. The tapping is much more natural to me now, rarely "touch" the basses these days. (pun, haha)
