are the "80s" ones the Rat 2? i've always wanted to try one.
there's never going to be a shortage of Vintage Rats, they just made way too many for that. ebay will be flooded with them, and many people make copies, schematics for the simple circuit can be found online, etc...
i reccomend the deucetone, it has TWO vintage rats in it! each one is switchable between Vintage, Turbo and Dirty (channel A) or Clean (ch. 😎 too.
you can even plug into just one of them for some reason. anyways i have one and i think it's great, the end.

any fan of older blur material needs one of these. it's quite easy to obtain the sound of what was evidently graham coxon using his two rats at once, and his overdrive sound is abound here as well.
also, using the clean rat with the tone boosted up in conjunction with a dirty rat with the tone turned down is an extremely high-gain yet clarity-up-the-bum sound that's totally bad-ass and completely crazy.
