Or at least that's what I was told I got in trade. The person I got it off has emails between the original owner and Fargen. The mods described in the email, or at least the visible ones like Mercury Magnetics parts, match what's described in the email. All I have to say is that the result is pretty impressive. Perhaps the only thing I don't like is the first of the two gains pots, but perhaps there's only so much that can reasonably be done with what he had to work with. I'd highly recommend getting mods done by Fargen or, getting an amp modded by Fargen, or just straight-up buying a Fargen based on my experiences with this amp. One of these days I'll try to A/B it against an unmodded one. edit: My grammar sucks when I don't sleep well.
