What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

À lot of ajustement are available. Dépendant on your instrument this amp will suit it.
Rated 5/5

In a world of class D amps, this solid state design still reigns supreme

The Ashdown ABM series is one of the few solid state amp heads that still remain on the market. There is a reason for this. This amp hits very very hard. The low end is much more warm to my ears that the low end of a class D amp. The drive control is another feature that stands out. It truly sounds like a warm tube overdrive. It is not a harsh overdrive/distortion by any means. It's a nice subtle tube warmth tone. This amp has volume for days, and can tackle any stage. The 9 band EQ is a much needed improvement over the the EVO III, since it gives you more flexibility in the high end. Ashdown amps are known for the warm tone, and the IV gives you more brightness if needed. I LOVE this amp, and cant recommend it enough

Very Good

Just received this week with the 4x10 cab.
Very good sound and a lot of tweaking.

Punchy bass good treble, I'M Happy !!!!
Rated 5/5

How it should be

After 3 forays into lightweight class D amplifiers I had enough.
There is a reason this is pretty heavy. Power on tap, headroom and a lush sound. Moving heavy cabs on your own is an issue. So get a quality light cab, but don't sacrifice headroom and proper power for a bit of weight in your amp head, I did and I won't again. This does the job without breaking sweat. Fantastic equalizer, compressor meh.. Not needed anyway. Engage the tube drive just a touch and it puts the icing on the cake.the The octave feature is interesting and sounds great prob better for slow stuff. This reminds me of all the tanks I've owned in the past and why they sounded so good. I love it
Rated 5/5

In love

From the moment I plugged into this cool looking thing I fell in love. Warm and defined and the EQ is super versatile and easy to use, don"t be put off by the rotary and slider EQ section it"s very easily to quickly dial in pretty much any time you want with real British authority.
