Thank you for this detailed breakdown! I will give this a go! I greatly appreciate it!!!!
The only issue you are going to run into, is that unless you have very tolerant neighbours and your hearing is still 100% (for now), you may not be happy with the results.
As Edo explained to me, the edge of breakup you hear in Edge's AC30's (when he's using them), is the power amp. breaking up, not the preamp. In order to achieve that, you have to set the Master Volume at 10 and the preamp volume at about 1/4. Those settings make for a very, very loud amp. but they also make Edo's presets sound magical!
I have power scaling circuits on both of my amps. So I can set the Master Volume at 10, but keep the level way down...no louder than what I would set the television volume at or the level I would set the headphones at, when using the amp. and cab. blocks.
If I recall, when Edo used to use an amp., he had a power soak. I believe when he plays live now, he goes straight to PA and uses the amp. and cab. blocks of his II. If you listen to the stream of the show he recently played, you'll hear how good it sounds. Then again, Edo can make a shoebox with elastics on it sound amazing! Not only is he an amazing player, he knows his Edge 'stuff' and has an incredible ear for tone.
