That's actually quite funny gwem - cos what you don't know is that with humbuckers, I want/need the two volumes - and two tones actually :lol: (I felt a little out-of-my-depth on my Explorer when I first got it - only one tone...)
How the hell I switch from master volume to dual volume, I've no idea, but it just feels natural going between fender and gibson.
The only single coil guitar where I feel stuck with master vol and tone is my Danelectro - the bridge and neck are so different, I need two tones, and two vols really (for the middle position). The originals have them, dual-pots, but haven't got round to tracking some down yet...
On this John 5 thing I could get used to the two vols easy... but no tone? :(
