Allen, they are great and once you add in the EQ / filter section it is over the top with goodness. If you check out my Tuesday Tester link below, you can compare it to a fair amount of other preamps you may be familiar with. There are 3 versions there also, stock / partial mod / full mod.
Thanks for testing out the modded versions War. I've been pretty curious about it. Would you say the mod affects the character of the EQ at all, or is it mostly to beef up the Preamp section of the unit?
I don't own the 7602, but have used them on a few occasions, and borrowed a pair from a friend for a month or so a year back. Instantly fell in love with 'em, mainly regarding the EQ section, but the preamps were no slouch either.
I'de also recommend the JFET Hamptone kits if you're handy with a soldering iron. Great units IMO.
