Purple Warmoth LP JR with Warmoth birdseye/ebony and a coil-tapped JB
Flat black Warmoth strat-style with Warmoth maple/ebony neck, Wilkeson bridge and Duncans
Blues Saraceno body with USA custom maple/maple, Duncan bridge and Gibson open coil neck
Joe Pass Emporer (early MIJ model with the pickup switch on the lower "horn")
'50s Epiphone archtop with an added cutaway and JB in the neck
Gibson J-45 acoustic

I also have mandolins, tenor, alto, bari, straight soprano and C saxaphones, several trombones, a couple trumpets, a wood clarinet, a flute, 60s Ludwig and 90s Mapex drum sets, 3 accordions, a Rhodes, a Hammond with an added percussion kit (poor man's B3), tons of barred instruments, penny whistles, and recorders, a conga... it goes on. My house is fun. As far as amps, I have a late 60s Super, a late 60s Princeton, a Fender M-80 halfstack (laugh, but the clean sound is unique), a 72 Bassman 100 with the crazy matching cabinet, Marshall JCM 800 50w 2x12, Line 6 1x12 combo for laziness and a SWR bass 350 (early one) with 4x8 and 1x15 cabinets.
