All-natural acoustic tone in an ergonomically designed high performance package.

The UltraSound DSX acoustic guitar combo amplifier pumps out 100 watts of incredibly pure warm tone through its two 8" Mylar coned coaxial speakers, which were specially engineered by UltraSound for all-natural acoustic tone reproduction.

The DSX combo amp is perfect for smaller venues in a solo arrangement. (For louder venues and playing with a band, purchase the DSX XTC cabinet and complete the entire DSX PowerStack for a rich full volume sound with 100% All-Natural Tone.)

The UltraSound DSX combo has 2 channels, including phantom-powered microphone inputs for each channel. Each channel sports its own volume and active EQ. Additional features include a studio quality DI, effects loop, Extension Speaker Jack, and an additional Aux. Input for Tape/CD. To further enhance the DSX, the onboard 24-bit digital effects processor produces studio quality reverbs, delays and chorus effects, which can be routed to either or both channels.

CHANNEL-1 is designed for both MIC level (XLR) or Instrument level (1/4") signals. (The 1/4" TRS Tip/Ring/Sleeve input jack is suited for equipment such as high-impedance microphones, keyboards, and drum machines. It accepts both balanced and unbalanced inputs) (Channel-1 is designed as a generic flat response channel that is suitable for any acoustic instrument level or microphone signal).

CHANNEL-2 is designed primarily for acoustic guitar and is equipped with an 18db cut Notch Filter that is used to control resonant feedback and amid cut SHAPE circuit to eliminate any mid range "quack" from you pickup.

Great amp for the money

By Jim L

After reading and re-reading mostly positive reviews on the acoustic guitar forums, I decided to try this amp. FWIW, the Ultrasound amps seem to be the preferred brand for this price range.I had a chance to work on tweaking a sound out of the Ultrasound ... I like it. I have an Aura Blender and found it sounded pretty good. I added a Boss EQ pedal to the mix and it sounded even better. I also set up my old Trace Elliot and did the ol' A/B test ... and the Ultrasound sounds as good or better at less than half the size and weight.Since my two guitars with pickups have a Fishman Matrix (no tone/volume control) and an Infinity (minimal tone control), I do wish the Ultrasound had a little more in the way of tone control, but I'm sure I can adapt. I'll be looking for a better quality EQ ... it never ends ;) ... If your guitar has a basic eq, this really shouldn't be an issue.This amp is really ideal for smaller/medium acoustic gigs. It really puts out a lot of quality sound for such a small package.

I just purchased this amp from MF. I had read many reviews before buying and the Ultrasound received very high marks. Well I have to say that I couldn't believe my ears when I played my Epiphone AJ 500RE through it. The very fact that the rich guitar tones of my guitar weren't altered is a tribute to it's transparency. It reproduced my guitar's unique timbre without discoloring it at all. The controls are simple but very accurate. I found the effects a little lacking so I simply ran through a Boss DD-20 Delay and Boss CH1 chorus could not stop playing. Pure tone heaven with rich clear highs, subtle mids and wonderful rich lows all coming from two 8" specially designed speakers that sound incredible. It is a true acoustic guitar amp. I will add the extension cabinet shortly to make the DSX model combo complete. Only 26 lbs, the cabinet is beautiful and looks vintage and expensive yet the price is very reasonable compared to its competition. I definitely was not disappointed and can hardly wait to turn it on again.

Tried two of these amps. Both had problems. First amp came and sounded like a fuzz ball was in it.. when I was packing it up to return I saw a Chunk of something attached to speaker (looked like wood chip)Company took it back and sent another, but it had same fuzzy sound, after a few minutes. (But no wood chip). I bought this because of the acoustic mag write up. Very disappointed. Guess you have to be careful with recommendations?
