Yeah, you definitely COULD NOT REPLACE THE TONE that the P-90's created (big fat warm sound that could get nasty if you purposely overdrove the preamp ). NoisyDad, the biggest problem I had with mine was, that it was noisy.
I wouldn't necessarily perform with it in my surf band, but I'd use it everywhere else (including recording with my surf band!). It was simply the best-sounding, most versatile, coolest-looking guitar I ever owned. It was tobacco sunburst dot-neck with black P90 pickups and a Bigsby.
If I had to pick just one of my long-lost guitars of the past to have back, it would be my Gibson ES-330.
