I am going to put up an SD-1 on ebAne soon, standard MIT with no mods.
Think I paid a bit more than twenty USD, but it's going up for auction soon. Mine works fine and does what it does.
I'll put it in the appropriate folder and give first chance to those here before it goes on ePay. Hate to part with any Boss pedals, but want them to go to good homes.
Any one wants to throw an offer out there go ahead or email me... cheers
