For what it's worth, I had the '68 CPR and the '65 PRRI side by side for a couple of weeks. I thought the tone of the two was very similar, with the '68 having a bit more "congestion" in the mids. I did try the '68 through an Alnico Gold and also through a Jensen Alnico Blackbird, and neither really changed things IMO. I had an AC15C1, but now have an AC30HW2. Honestly, I can't think of an either/or with the Vox vs Fender; I like having both around.
