Like you, I don't really use the guitar's volume control at all and although I use the tone control more, it's hardly frequent. Certainly when I want a distorted tone, I find that backing off the volume just dulls the tone and takes away the compression and saturation I like. Having said that, unlike you, I don't think this is down to old school vs new school. Instead, I think it's got a lot more to do with my lack of skill and ability in making it work for me. If I watch a video of Gary Moore, I notice that he's constantly playing with the controls on his guitar to manipulate the tone and that's a lot more than simply 'old school'. That's a guitarist who is a billion times better than I'll ever be and he's doing it for a reason and not because he shuns modern technology. No, to my mind the problem lies with us, not the old school players who use the controls on their guitar.
