yeah, Tim made a t-top replica for a while, but honestly, I don't see the point
the riff raff is a much superior pup than the gibson t-top or the original 70's dimarzio PAF, which was also a t-top replica
the riff raff is more full sounding and bright without getting fizzy
and it also handles any amount of gain beautifully, unlike any gibson pickup is able to do
the early 80's gibson tim shaw is a little warmer than the riff raff, but doesn't handle gain well, in my experience
I'd pick the mule for that warmer character, although it still keeps lots of clarity, but the stormy monday might be a little closer tone and outputwise (compared to the tim shaws, not the t-top)
