Yup, biased at 90v.
The amp will have a power switch in it that'll take it from normal to 90v and adjust bias at the same time, John is putting it in next time I swing out to the shop- he was going to put it in the other day but wanted to make some changes in its design so we just went with a regular power switch got now.

Heading over the TGP now to read about the inevitable EVH/Plexi debate that I'm sure is raging...![]()
