Hi. I've been looking at a Peavey Firebass 700, and I noticed that there seems to be two different models of the blackface version (I know there's also the whiteface which has a slightly different preamp, too). I have seen a blackface version which has chrome corners on it, and there's one with black corners which you can see a green PC board on through the vents on the top front of the face. Does anyone know if there's a difference in these two versions? It looks like the black cornered one has this extra PC board (or it may just be a larger PC board). Is there a design difference between these? Which version is the newer of the two versions? Thanks for any info!
