The Morgan AC20 Deluxe Amp is essentially an all hand-wired, hand built, fully modded version of his very popular AC20. In fact, now that this is available, he is rarely asked to build the normal AC20 these days. What sets this amp apart from the Morgan AC20 is four things:
1) A switch on the back allowing the guitar player to switch from an EF86 preamp circuit to a 12AX7.
2) Normal or Brilliant channel voicing
3) Power Scaling
4) White Faceplate as opposed to the AC20's Black Faceplate
All this makes the AC20 Deluxe one of the most versatile Vox-ish type amps available for it's size.
So how do we describe the AC20 Deluxe's tone? Well, Joe Morgan based this amp off of the "Normal" channel of an AC30, and intentionally voiced it a bit darker. All the wonderful chime and growl is still there without the annoying "icepick in the ear" that plagues most Vox designs. And what may be the part is it's only 20 watts. An AC30 is 36 watts, and to get real tone out of them they have to be cranked! Believe me, 36 watts of EL84 power can peel paint off the walls. With the AC20 Deluxe, you get an amp that is plenty loud enough to play over a typical drummer without having to blow windows out of the room to get the tone you need.
With the bright switch off and a decent treble booster think Brian May. With the bright switch engaged think U2.
So, in a nutshell, here's what we have with the AC20 Deluxe... A lower wattage modded AC30 with all the things people dislike about them improved upon. There! I said it! :)
