I didn't try it the last time I was there, but my local guitar shop has a custom Gibson Les Paul w/ dual Dirty Fingers in it. The shop boys say its a real beast. I'll be sure to post my thoughts after giving a good work out. If you want, I can test it through a certain amp, should they have it. They have most of the tube Fenders, Marshalls (mostly tubes but some MG's), Orange (crush series, Tiny Terror, and a few high end heads w/ cabs), and Peavy's of all types available for play on the floor. I usually play through the Fender Princeton Recording Amp when I go, but if you request a certain amp, I'll be sure to use that one w/ it to give my own thoughts of how those pickups used w/ that amp sounded.
