The only real mod I can see modding the Vintage Modern for is the Lead Master so you can have rhythm work and lead work volume seperate.
Other than that I like my cleans on the verge of break up anyway so my playing dynamics on how hard I pick and how I use my range selector can do convincing clean work.
As for the volume difference I don't see it that big anyway.. distortion is supposed to be more in your face anyway when you switch to it.
Here's an Elvis Presley Cover I did with my drummer, I use everything from low range light picking to full on High Dynamic range at the end. For most of the song I'm in low dynamic range and I don't even use my volume knobs to adjust for gain, just the footswitch and my pick attack. all 4 volume/tone knobs on my guitar are on full.
Lets see how many of you can guess the exact time I switched into High Dynamic Range.
I am pretty proud of the fact that the VM went from mostly clean to full on distortion so smoothly. I think most of you will be suprised at the smoothness of the transition from LDR to HDR.
