i have a couple of the brass ones a fellow TB'r gifted a few members with,work great!,i like mine paralel to the E string with allows me to use the neck,thumbrest,or the pickup on the P,on an SX J i recently bought it had a TALL chrome one,to tall,so i swapped it for the second brass one paralel to the E strings so;i can park my thumb in 4 spots on that bass
the'tug bar' for thumb playing,no but i've considered it on my fretless J since i use that for dif stuff like bluegrassy,havent lately but i wouldn't be afraid to,thumb playing has it's merits talking country,western swing type stuff,if there is no drummer and you have to lay down the one-TWO,one TWO etc thumbing the e,a and finger picking the higher register strings it's easy to lock down the groove.
if jamming to Black Sabbath i don't thumb play
oh ya,i attach mine with Scotchmount super attachment tape(autobody),,Ozzie or Waylon has never noticed i didn't use screws

that way you try one and no need to drill holes

ok now where WAS i going here today(got lost opening this post)
