BT-350ThunderBass Amplifier

Introduction:

The Crate BT-350 ThunderBass amp is a high-quality bass guitar amplification system that combines extremely high power with very desirable features. Each feature and control is discussed in detail in the sec- tions entitled “The Front Panel,” “The Rear Panel” and “Using the Biamp Capabilities.”

Crate offers a heavy-duty three rack space enclosure (Crate model #CR-3) which will house the BT-350 perfectly, providing the extra protection and convenience needed when you take your Crate on the road. Also available is a five rack space enclosure (Crate model #CR-5) which is ideal for use when the BT-350 is combined with a second amplifier for biamping.

The BT-350 is equally suited for use in the club, the studio or on the stage. When combined with Crate’s line of superior bass cabinets, the results are nothing less than phenomenal. (But then, what else would you expect from Crate?)
