I used to have a Tim. I believe it was the original version, it did have the toggle switch on top. Now, on mine I could use it as a dual overdrive, meaning I could have the boost (left footswitch) on separately and it worked, regardless of the setting on the footswitch on the right. If I accidentally turned that boost off I lost tone and volume (even if the right footswitch was off). Is this normal behavior for the Tim, or was mine possibly modded? I have people telling me now the boost never worked unless the pedal is already on. Later that right-side footswitch label was changed from "on" to "bypass". I know the pedal had a few different versions. Is it possible some of them were made to work differently?
