      Comments about Behringer ULTRACOUSTIC ACX1800 Acoustic Guitar Amplifier:

      I tried to purchase the ACX 900 but they were out of stock. So I took the 1800 instead. I put it next to my Marshall 50w amp and found the Marshall was much more powerful. I called the factory and learned that the unit is sold on peak power and that both the 900 and 1800 are about 60w RMS which is about the same as the Marshal 50w. For this level of power I find it quite heavy and the Eq is overdone for my needs. I will try it in a gig this week but I think I will return it and try something less cumbersome to carry.

      Good Deal


      from Williamsburg, OH

      Comments about Behringer ULTRACOUSTIC ACX1800 Acoustic Guitar Amplifier:

      Overall pretty happy with this amp. I own 3- other Behringer amps, and have been very happy with them. I will have to say that this amp just does not have the same volume or lows as my ACX1000, which it is supposed to be one step up from. Also not crazy about the user interface with the effects processor- again think that the ACX1000 was a little nicer. Can't beat this amp for the money!
