Re: NAD?
Sweet amp! How do you like it?
Quite a bit so far, though I'm still getting to know it.
It's one of those amps that has a defined signature tone, that you can color and shape but never really change. When the circuit isn't great in an amp like that, you wind up with annoying frequencies that can't be dialed out. When the circuit is good, you get an amp that is almost impossible to make sound bad.
The Superdrive circuit is very, very good.
The clean channel is Fender-ish and chimey, but with more lows and body like a Marshall, and the headroom of a Hiwatt. Superb.
The drive channel is an interesting beast. British in flavor and feel, but with a huge frequency footprint like a vintage Matamp, or a Mesa Recto.
The mid knob has a push-pull function that realigns the EQ curve, hollowing out some low mids and changing the frequencies affected by the EQ knobs. This mode brings the amp much closer to JCM 800 territory and sounds great, but I think I prefer the "bigness" of the standard tone stack.
If I had any criticism at all, it would be that this thing is loud LOUD L O U D. Louder than I will ever need on any stage that I will ever play. The master is a good one, but even at 9 o'clock on the dial, it's pushing more SPLs than my 120-watt Splawn ever could dimed. Nuts. I may wind up using an attenuator or something. I'll know better after I take it to a jam.
