Here's a playthrough of my modified Peavey 6505+
(Detailed description of the mods below)
Cleans: Now truly a Fender type clean, very glassy and bright. The bright switch was changed to make the channel not as dark when disengaged, but still different enough and usable.
Crunch: Much more of a Marshall feel. Not really anything like the stock green channel and a little lower gain. This channel is now lower in volume as well to match up better with the clean volume.
Lead: This is where most of the modding took place. The original idea was to convert this amp to be as close as possible to the Soldano SLO, which is what the 5150/6505 heavily based on. I started off getting the lead to 5150/6505 spec, and then some tweaks got it as close as possible to the SLO. The mids are much thicker sounding, the low end is chunky, and the treble is not nearly as harsh and fizzy. The switch you see is part of a revision I did, and that switches between the 5150 preamp with SLO mods, and the 5150 ii preamp with SLO mods. Basically a 5150/5150 ii switch and the overall amp was made to sound more like the Soldano.
Presence: I raised the frequency that the presence works at on both channels quite a bit. There is a lot more clarity and high end bite and air now.
Resonance: I did lower these on both channels by nearly an octave which was a ton of fun when just playing through a cab. The amount of deep, punchy low end was insane and put just about any amp I compared it to to shame. However I found that it was too deep and boomy for recording purposes, so I changed it back to stock.
