Bought a bridge SD Antigua 2 and an old 73 Jazz pickup in the neck, replaced the flatts with round wounds and put all on the fretless, more growl now...
Deft has retarder in it and I know what you’re feeling, I put Retarder in my Lacquer for my Jazz Bass project and hung it for two weeks sanded and polished laid it in a sketching pad an etched the edge of the pad across the back @%$^$##*?.
