I have a modded Boss SD-1. The mods are supposed to bring it to the level of the Ts-808 with the same op amp as the 808, tantalium caps, ect.

It has completely change the sound of this pedal-for the good! The bass end has been cleaned up, the volume has increased overall. The sound has opened up and is unmuffled. I have 40.00 in the pedal, pawn shop deal, and I am VERY satisfied.

Now while I cannot comment on the TS, YMMV! ;)
