The Sienna 30 is a 30-watt combo amplifier with a 10" speaker that is specifically designed to reproduce and enhance the natural sound of your guitar or other acoustic instrument. The approach is more "hi-fi" in nature. One 1/4" instrument input plus a 1/4" microphone input add flexibility for interfacing with the amp. You'll also find analog Reverb and Chorus effects to enhance your sound. EQ controls include a Feedback filter ” very handy for live gigs. The Kustom Sienna 30 lets you fine-tune your sound, and then amplify it in a way that brings out its best qualities.

Very multidimensional amp

By Alex

from NY,NY

I was looking forward to a good amp, however this amp surprised me. Through my Seagull, the feedback control is much more useful than I had anticipated and the chorus is clear. I plugged in my Gibson Les for kicks and found out that this is more than just a typical acoustic amp. With a turn of a knob, my Les sounds similar to an ES-330 hollow body. I was very impressed, and after putting in Seymour Duncan Jazz pickups the jazzness of the guitar is amplified through the amplifier. Great with acoustics, surprisingly great with electrics.

Great Sound!

By Jeff Smith

from Arizona

Kustom Sienna30 is a very good sounding and solid amp. It?s compact, yet, loud. More than adequate volume for small venues, like coffee houses or any room where you?d be playing for less than 50 people. I can?t compare it with all other acoustic amps but, I can tell you I like it better than Behringer ACX450. I ordered the Behringer and even though the specs on it looked good on the paper and it had lots of bells and whistles I wasn?t impressed with its? sound nor its? volume which is rate it at 45 watts so I sent it back. The Sienna30 is louder at 30 watts and it produces a better acoustic sound and it has important features that the ACX450 lacked, like Speaker Out, Line Out and effects loop. I used a Dean Markley Pro Mag Grand (humbucker) soundhole pickup with the sienna30 and the combination of the two blew my mind as to what a nice acoustic sound they generated together. I also used an acoustic electric guitar with Piezo UST pickup, it also sounded awesome. I?m not a big fan on using effects on an acoustic guitar but I?m glad this amp has the Reverb and the Chorus. The sound is awesome without these two effects, but, I?m sure there will be situations where I may need to use them very conservatively. The volume to the mic channel is equally as impressive, where the Behringer ACX450 mic?s channel volume was drastically lower than the guitar channel. I?m very happy with the purchase of Sienna30. I believe it?s under valued and a great bargain. If you can buy it on sale then you got yourself a really great deal! My gripes about this amp are minor. First off I wish this amp had an input jack for a Drum machine or CD/MP3 player in addition to the guitar and mic inputs. Secondly the jacks on the back are a bit cumbersome to connect to since you have to shove the cords from underneath where there isn?t a whole lot of room to work with and I have small hands. Also I wish the name of every input jack on the back panel was printed right above the jack if not horizontally for there is no room, then vertically. As it is now you have to refer to the pictorial graphics on the back panel to see which is which. And last and this is matter of personal preference, I wish the names of the knobs were printed in reverse. The way they are now you can read them right side up if you are standing in front of the amp but we the musicians are usually behind the amp so we can avoid feed back and if we need to make any adjustment we do it from behind the amp. Other than these minor gripes THIS AMP IS GREAT!!
