Tonepad TS808-log drive pot?

[ragtime8922]

Tonepad has two layouts for the Tube Screamer and they have different pot types. One lists the drive pot as a 500K linear and a 100K log volume  pot. Version 2.2 on Tonepad lists a 500K log drive pot and a 100K linear volume pot. Experience tells you that vol is log and drive is linear but I don't want to assume. What do you guys think?
