The Sienna 35 is a 30-watt combo amplifier with a 10-inch 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-inch instrument input plus a 1/4-inch microphone input add flexibility for interfacing with the amp. You’ll find eight 24-bit digital effects, like Reverbs and Echo, to enhance your sound. EQ controls include a Feedback filter – very handy for live gigs. The Sienna 35 lets you fine-tune your sound, and then amplify it in a way that brings out its best qualities.
