I have recently bought Epiphone Masterbilt DR-500 MCE, fantastic sound, plays like butter etc. It has installed Preamp E Sonic 2 HD. I cannot find manual for this version anywhere (even on Shadow Electronics website there is only E Sonic 2 (not HD).
I have one question: does your built in tuner work only if the guitar is plugged in? I have also electro-acoustic Fender with Fishman preamp and it works with plug and without it. I barely use mu guitar with amp so actually tuner is not available for me. If there is on/off tuner button it does not cause increased use of battery. Strange thing...
