I never understood why anyone would be scared by knobs or switches.....all it means is you have more control over your sound. As long as it sounds good, the extra options can be a blessing for someone who needs different tones on the fly.
Are guitarists that close to cavemen? Try a keyboard/workstation compared to a 4 Channel Marshall.
Anyhow, before the new Marshalls came out, I had a slight feeling the JVM would be a cooler amp than the Vintage Modern, even though everyone assumed the opposite. Everyone who's scared of knobs assumed the VM would be better. Now that I've played both, I have to say the VM is the worst sounding POS Marshall I've plugged into in years! I hated it. I couldn't get any tone that sounded good to me. The JVM, on the other hand seemed like something useful, and it's one of the better Marshalls in recent years IMO. Still no Bogner tho. I went from playing the JVM for an hour at GC to my Ecstasy at a rehearsal space, and was reminded that Reinhold Bogner completely owns everyone.
