Hi!
Yes, I do have two Power Jazz Bass Special basses! I adore them. They are the kinda bass that would have to be prised from my rigor morticed hands, you know? I never really cared for the on-board electronics and thus I stripped the lot out and replaced them in true 80's style with a full active EMG circuit. They sound amazing. Interestingly, they actually both sound different - but lets not start the "tone wood" debate here too lol..
As for the Tri-Lam neck, yeah I never really cared for or bothered to chase up what was actually meant in the somewhat vague marketing literature. Being something not visible, I wondered if they had inserted rods in the neck like many brands do today to "stabilise" them. I've no idea, but these are two basses that I don't think I have ever adjusted the truss rods for since an initial set up, years ago. They are rock solid, the necks are amazing and they have a great sound. Gotoh OEM hardware too, if you can find a good example they will p*** over any modern Mexi - and I like some of those MIM basses too
