Both very cool for what I do but not my first choice for dirtier tones.

dangelico, that is interesting. Looking at that schematic for the EH-185, I see big resistance in the cathode bypass caps on the preamps and no bypass cap at all on the cathode biasing circuit for the power tubes. Those two aspects would keep things clean, wouldn't they? That approach seems quite different form LEo's approach. Just curious.... Gibson was probably looking for that cleaner approach because the pickups that Gibson built have a bit more oomph than the Fender single coils from the '50's.
