How to tell difference between DC-5a and 5b?

[snave]

I understand there are some pretty big tonal differences going on in Ch 1 between the A and B series, so what are the cosmetic differences to tell the two apart?

I've seen models with and without LEDs by the inputs. It looks like those metal chassis screw brackets on top of the headshell aren't on all models either.

The A came with plastic rockers initially, and then with metal switches, whereas the B's were all metal switches. Not sure on the LED factors. The clean channel on the B has a higher headroom, and the reverb is supposedly more dramatic. I like my A a lot, I dig that the cleans get a little furry when pushed.

Search on here, this has been discussed here many times. I own number 0009 and it has LED's. and Metal Toggles. Hope this helps

The difference is described in this thread. I think it's around the 4th or 5th post.
