As it turns out, I also happen to have a 12AT7 and a few 12AX7/ECC83 tubes in amongst my stash of tubes too, maybe I could do a tube shootout audio demo once I have finished building the pedal and it's working so that those who want to build one of these Persuader pedals can hear what the three different tubes sound like in the pedal?
The persuader pedal is powered by a standard Boss-style 9V DC plugpack adaptor, but, you can also (and I would recommend it) power the pedal by a standard 12V DC/500mA plugpack adaptor too, provided that you get the polarity of the DC plug and socket correct.
