It looks to me that the advantage of the Vintage Ultra is that the OD circuit can be blended in. I don't know if it is reasonable to switch back and forth, or if it is like the TH and has volume matching problems.
The advantage of the TH is that it is paid for.
That's what the Level control does -- balances the clean and OD signals.
HOLY CRAP!!! 25 American dollars for a pack of smoxe in Oz???
