Hi, I'm Cliff Unruh. The 3300 has become my favorite Leslie and we are seeing them grow in popularity for church use even though they are rarely moved in that application. Why? Because of the rugged construction, economic price, and the user-friendly custom controls that allow adjustment of high and low-speed RPM as well as ramp-up and brake speed of both rotors. With all the power and features of the top of the line 971 model in an “easy to move” package, the Leslie 3300 is one of the most powerful Leslies ever offered, and has been designed with the professional touring musician in mind. This single-channel Leslie features a two-speed horn rotor coupled to Hammond's newly-designed heavy-duty midrange/high-frequency driver and a massive 15” woofer which fires into the bass rotor. The Leslie 3300 is powered by a total of 300 watts RMS solid-state amplification with a vacuum tube preamp. Amplification is divided between a 220-watt dedicated bass amplifier powering the woofer and an 80-watt mid-high frequency amplifier for the rotating horn's driver. The 3300's 11-pin and 8-pin Leslie sockets allow connection and on-board control with Hammond Organs. Most other electronic organs and keyboards can connect to the 3300 using a ¼” cable along with a common foot switch (optional) for Leslie speed control. This Leslie features a rugged-built, high-impact finished black cabinet which is lighter than a traditional Leslie and the heavy-duty casters will make it a snap to transport to your next performance.
