Bloody CTS split volume pots!!

Tip: if you're upgrading a Hohner B-Bass V with an OBP3 and decide to put a 500K dual stacked pot in two put the two previous knobs onto one, BE PREPARED FOR SOME DREMMEL ROUTING WORK.

Fortunately, this will hold the new split pot in place without needing a grab washer! Win!

Ah, the fun of ripping an old friends guts out to replace em hehe





Speaking of ripped out guts... Old preamp.





And, 20 years newer, OBP-3, already wired for max versatility:





It's a bassist's DIY heaven!
