I didn't vote, becaue I Love both. I'm actually on the list for a 2nd Timmy so I can have 1 symm & 1 asymm... I think it could replace my FD2. On assym, with my rig, and the way I use the pedals, the assym Timmy sounded almost identical to the FD2...but better. So right now, I have the Timmy for symm, FD2 for asymm.
"the way I use It": my tube amp is already cooking, a good rhythm tone, I then use OD pedals to push the amp a bit more for solos... more gain/compression/sustain.
I don't know why, but I like symmetrical when the Timmy is last and asymmetrical when the Timmy is stacked before another overdrive.... I voted asymmetrical because that is how I'm using it at the moment. I also never use the compressed mode in either my Timmy or Tim.
