the VM is quite a nice amp I think the layout confused a few people coz it's essentially a 4 input control setup with blend knobs for the pre-amp sections (old Volume controls), yet it still has a gain control thats and a post pi master volume.
it's something like
Pre Volume, Pre-PI x2 Master Volumes, 1x Post PI Master volume
very strange setup, but I suppose it gets the results? I think the VM is a much nicer amp than the JVM. But I must admit I'd not trade my 800 for one.
As for my guitar it's an early 80s Schecter, the pickups are Mules. it came with single coils but they weren't brilliant.
