OD/Distortion pedals that come with an op amp socket? (...for IC chip swappers like me)

[Barnzy]

Can you list any OD's or Distortions that use an IC socket, so you can swap chips? I am a big fan of this feature and have a huge number IC's to use. I know about Barber and Timmy. Also the new FAT RAT... Do you know others?
Thanks,
Barnzy
