I've been hauling around my first "real amp" for many years. Back-breakingly hauled it up and down 3 flights of stairs (where each floor was 15 foot ceilings above a bar) where I used to practice.
But couldn't let it go. It was my thing. It's a beautiful, amazing amp.
However, life went on - married, had kids, and still wanted to have that incredible sound.
Ultimately, sold the AC-15 because it was just untenable in my home and bought this pedal hoping it would fill the void.
It's an astonishingly accurate replacement. I don't miss the original for a single second.
If you like the AC sound, but want the control (and the variability of different speakers, etc.) and want peace in your house, this is the thing.
Run, don't walk. Buy this thing.
