That might take away from BE100 sales.  He had a Plexi model that George Metropolous built when they had a partnership.  There were some clip of it at the time.  It was never said it was an EVH leaning amp just a plexi model.
Looks like it was 2011.................

After a few final tweaks and some critical listening the Metro-Friedman plexi collaboration amp is available to order.
The jist of the amp is:
aggressive plexi that begs to be dimed and retains detail at this setting
voiced for "brown" tones but also covers all the tones from '68 era and up Superleads
includes a 3 way power switch for OFF / ON NORMAL / ON VARIAC
the variac setting simply drops all the voltages in the amp, like an external variac set to 90V AC
6CA7 output tubes
1968 era specs
Price is $3,200 USD
The amps are assembled here at Metro. I should be able to start shipping in 3-4 weeks. Contact me for more info and ordering:

In the LA area you can stop in Tone Merchants in North Hollywood for a demo.
