Sounds like the DSL might be the most versatile option.I have heard many getting the VH tone out of all those amps you mention, but what I don't know is if they have a pedal on. And yes, the Studio Vintage would be the circuit they started with but then you'll have to find out just when Edward had it modded. If it was me I'd go with the DSL and settle for a great approximation. A lot of difference between a 20 watt amp in your house and a modded 100 watt in a major studio, so the SV might not be any closer, plus you get all the bells and whistles. And an FX loop for the LBB. As for "dry", I remember those albums to have some phase shifter here and there and delay on every song. And don't forget ted Templeman drenching everything in all the reverb he could beg borrow or steal. I suggest a clean boost, phase 90, Digitech Obscura and a Wampler Faux Spring.
