Hi Craig,
I have an Abraxas set in a Hamer Sunburst and it sounds great. The TO song Outlanders has a great example of an Abraxas neck pickup when Jimmy plays his intro - it is very Floyd'y sounding. The bridge is bright with a hint of compression in the tone (as you would expect), and as a set they go together very nicely. I had VHII's in my PRS Artist II (22 fret, hardtail), but changed them to Mules as I wanted a bit more open sound, the VHII's sounded great but they were a little to bassy for the sound I was after from that guitar.
