Last year we had most of the pickups at the show. The ones you usually won't fine there are the custom order ones (ceramic WP, 7-String and bass pickups). Tim brings along a great selection of guitars loaded with most of the humbuckers along with a couple of Strats and Teles. For the last 2 years we have had 2 of Tim's Zakk Wylde heads each with thier own slope 4x12, and last year we had the H&K Alex Lifeson and Duotone with cabs too.
Not sure what will be there this year for amps. You will be able to buy the pickupsat the stand, though last year the MQ's went quick! I know Tim and the guys will be gearing up to build as many sets as possible for the show.
