Re: S-S-H volume level/balance...
I'll likely be getting new electronics (removing the existing loaded Carvin S-S-S pickguard), so I could do either/or. I only know of the JB using 500k pots, never tried 250k (but I know many like it).
Do you know offhand how similar (or not) the VR is to the DiMarzio Cruiser? There are players who use a pair of Cruisers with higher output bridge humbuckers with good results, and I'm wondering how that would fare using VR's instead?
