Good thread.
I've had two Squier JV Precisions, both at the same time, still got one. The first was a really early '82 Fender logo '57 RI in tobacco burst with a maple neck that I bought from @LukeFRC a few years ago. Weighed 9lbs on the nose and had a real vintage P bass tone. The second was an '83 in black with a maple neck. I'm not sure but I don't think this was a '57 RI model - anyone know? It weighed 8lbs on the nose and has a far more aggressive tone to it. The maple has some figuring on it and it is the bass I like the most of all those I have ever bought. This is the one I've kept.
I've had three Peavey Fury basses - the Mk I single pickup P-bass-a-like. They all sounded similar, very close to the black JV P bass above in that they are an aggressive Precision tone. More so, in fact - the pickup reminds me of the Entwistle PBXN. But the weight varies hugely. The first one I had weighed 8.5lbs, the second one nearly 10 lbs, the one I have currently (the keeper) weighs under 8lbs. Really nice basses that cost peanuts.
Hohner B2 basses. Ostensibly very similar - B2, B2A, B2ABD. Had all of them at various times. The weight again was extremely variable from 7lbs (B2) to nearly 9lbs.
