I play a couple of high end acoustic guitars. I had never considered until now to purchase an acoustic amp. I finally made the move and I amnot disappointed. The proble with many musicians as my Luthier has stated is that they buy low end instruments and expect equipment to make them sound better than what you have paid for. I feel I have made a steal with this amp and have no regrets. Once I went direct XLR to my PA system I was blown away. I don't rely on effects, so the sound is clear, bright and no distortion as one had mentioned in an earlier review.

I own several Behringer products including 2 of their small amps and am very pleased with the items I own. I was NOT pleased with this amp. The amp microphone effects circuit went haywire and was making loud irritating sounds, WITH AND WITHOUT a mic or guitar plugged in. Additionally, the effects send circuit had a short. This perhaps reflects quality control. As I said, I have other Behringer gear I am happy with so I was surprised by these issues. It's gong back and I will not reorder this. I need A RELIABLE ACOUSTIC AMP. Although more money, I going for the AG60 60W 2x8 Acoustic Guitar Combo Amp. Maybe I just got a lemon......

        Comments about Behringer Ultracoustic ACX900 Acoustic Guitar Amplifier:

        I have owned this amp for about 7 years and have used it a lot. I can't fault it on how well it has held up to constant use and being moved around to gigs but it has never sounded that great. I did not realize how bad it sounded until I ran my Martin direct into my new PA system. If you can't afford anything better I guess it would do.

        I bought it about a year ago and I used it all the time at home. This year (2014) a friend of my hang around with me and he plays acoustic guitar too. I hooked up my Martin and the microphone on my side and he hooked up his Takamine and microphone on the other side. we jam together for three hours and every thing was excellent. We started using it all the time since then, no problem.

        Don't buy this amp. It looks very nice, vintage, but after all you will regret. Sound is not so bad, but amp is very, very weak.

            Took it out of the box, plugged it in, lights on chan 1 flashing with nothing connected. turned tuner and phase and feedback off to get sound. Amp sounded terrible. Connected to chan 2 and was quite suprised how good it sounded. Went back to chan 1 and it was bad. Returned it and will try something else. Amp does look nice and vintage, too bad it doesn't function as promised. Mfriend was great about the return.

            Great with GR setup

            Comments about Behringer Ultracoustic ACX900 Acoustic Guitar Amplifier:

            Good buy for the money but if you can afford it go for the 1800.
            Plug my GR33 into the CD input in the back and run ther guitar out to the Inst. channel. The GR through the Aux in sounds as good, or better, as through my Bose computer speakers.
            Would have liked a master volume control and a little more headroom on the mic channel.
            Looks stuuning and everything appears well built.
            I've always had good luck wiith Behringer's products and this is one of my favorites.

            cool little Amp

            By

            Comments about Behringer Ultracoustic ACX900 Acoustic Guitar Amplifier:

            I know this amp is not the loudest amp in the world, but as far as a practice amp or coffee shop type gigs it's perfect. Ive had it for about 2 years and it still runs smooth. Honestly what really makes the difference in the end is the preamp system or pick up you have for your acoustic. I have a Fishman prefix pro and plugged into the amp it sounds really good. The cool things is you can use the amp as a direct in to a PA for a louder setup and still get all the effects you need and well as a really clean sound.

            Tinny and weighs a ton

            Comments about Behringer Ultracoustic ACX900 Acoustic Guitar Amplifier:

            This thing is small and still weighs a ton. If it sounded good, that would redeem it, but the tinny sound just could not be corrected, regardless of settings. I had Fender Acoustasonic 30 amp, which I would recommend over this one. Should have kept the Fender. I returned the Behringer right away.
