The HX/DA is truly a professional's instrument. It's just a great amp, easily comparable in versatility and quality of tone to anything out there.

The amp is dead quiet. Turn your guitarís volume all the way down, and there is no noise. None.

This isnít just about not having to hear background hums and buzzes when youíre not hitting a note or chord. Itís about the quality of that note or chord standing out against a black background and really coming to life.

The ampís clean tones are pure class. I say tones, because you arenít stuck with one sound. Not only can you tailor the tone with the switches, but the two gains, the tone controls, and the contour can all be manipulated to help carve great cleans, and again, these controls are useful throughout their ranges, not just in one narrow sweet spot! The detail in the note is tremendous, you really hear the guitar, the pickups, the wood, the whole thing.

There is a huge range of usable gain here at every turn of the knobs. There have to be infinite good tones in this thing. The tone controls work extremely well. You can dial in pretty much anything to accent some frequency of the guitar that you want to. This is not an amp where the tone controls only do something good in a small part of the knobís travel. It sounds good pretty much everywhere you turn a knob.

And even with the master pulled down, the amp doesnít get fizzy.
So, just a beautiful tone all around.

Itís also a forgiving amp to play, with a controllable, slightly elastic feel throughout its volume range.

Iíd like to mention the quality of assembly. PRS does a really nice job. Everythingís neat, thereís a tube chart, and they even thought of a slot on the bottom to have a place for the power cord.

The controls and switches feel great; that is, they feel like the pots and switches on high end studio gear or hi fi gear. Theyíre smooth, and there arenít any sticky controls or jumps in level as you rotate the pots. As always, with PRS gear, someone put a lot of thought into the overall feel!

I've played lots of amps in the studio that claimed to do the things this amp actually does, and couldnít find one in a Plexi style that ever truly sounded as good as it claimed to. This one does.
