No idea what the difference is as beyond cosmetics, but I bought the OD808 because it was cheaper and sounded identical.

i meant ts9 vs od808

You said 808 was cheaper? isnt he ts9 cheaeper

TS9 has a more modern voicing IIRC. If you're using it to boost an amp for metal, get it. Otherwise, get the 808.
And the OD808 is cheaper than the TS9. At least it is here in England.

I've got the TS-9 and it is amazing, so good choice.
