Boss OD-2

I just picked one up on ebay out of curiousity. Does anyone use an OD-2 and if so how does the "non turbo" setting compare to an SD-1?

I've had one for 20 years and I really like it. I've never tried the SD-1, but both the Turbo and non-Turbo modes have their good uses, to my ears.

i got a chad mod od-3 but didn't even get a chance to open it out the box yet! is the od-3 a later version of the od-2? if so, what is the difference?

The difference is that the OD-2 has two drive modes (Turbo and non-Turbo), whilst the OD-3 is just a straight-up overdrive unit, more like the OD-1 or SD-1, although I've never tried that either.

I've had one for a very long time. I haven't used it much for the last couple of years but still find it to be useful. it has some quirks like other BOSS ODs of the past such as bass gets tucked in. i did some very minor mods to address some of the issues and it's better.
