I'll see if I can find a 57. I have one somewhere. I also have a Rode NT2 that's from the late 90's (at least I know where that is!) Greenbacks / V30 / Lynchbak / Creamback / Redback on hand. I shouldn't overpromise though, AND it may take me a while to try it. I'll see what I come up with this weekend. I could run a couple cabs and just set the Rode up as a room mic at minimum with a little time moving cabling in here.
Regarding DeMartini vs old Aerosmith, it does both, just depends on how you attack the string in my opinion. This is from last night and I'm not trying to do anything, just literally the first couple minutes of plugging it in, but I think you could emulate the VH or DeMartini vibes. These amps are cool in that it gives you what you put into it... I hit the strings harder at some point and it reacts.
No pedals here, just a small amount (15%) delay mix post OX Greenback (no settings on OX other than a dry with eq cut above 10K).
I get what RaceU4her is saying too... that's partially why amps evolved since 68 right? For me, this is single note arpeggiated chord curiosity and I'm going to enjoy having it as an option
