The Sienna 35 is a 30W 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 find 8 - 24-bit digital effects, such as Reverbs and Echo, to enhance your sound. EQ controls include a Feedback filter — very handy for live gigs. The Sienna 35 amplifier lets you fine-tune your sound, and then amplify it in a way that brings out its best qualities.
