The Leslie Models 3500W features elements from the 122 / 142 Heritage models and remain the essential partners for any Hammond Organ, bringing vintage sound with a new level of hi-definition clarity and presence.
It offers 300 watts of bi-amped power provides the thunder, commanding any Stage, Church, Institution, or Studio. This new model is not for Organists alone because the 1/4” line level input allows fpr keyboards, guitars, etc electronic instruments to share the Leslie legend. A standard (optional) footswitch controlls the Leslie speed. No external “preamp box” is required.
The familiar 11-pin jack directly hooks up your Hammond Organ.
The 3500W traditional cabinet is attractive in any setting with its fine furniture Walnut finish. The styling of this cabinet is in the manner of Vintage Leslies, reviving Don Leslie’s original design for efficient acoustical response.
Horn Rotor / Horn Driver
These new models are equipped with the exact same horn and horn driver found in our exclusive vintage reproduction models 122H & 142H. The pre-1970’s style horn is widely recognized as a key component of vintage sound; while the new horn driver is based on the original V-21, recreating not only its speaking characteristics, but also its shape, which keenly affects the sound. The Horn driver level is easily adjusted with a dedicated control knob, allowing precise balance with the woofer.
Woofer
The new model’s woofer is the same as found on our models122H/142H. It was developed with the aim of reproducing the vintage 122 (C15L) sound; while being able to handle the higher output of the newer power amplifiers.
Control Panel
Equalizer: A 3-band equalizer is provided. BASS allows you to adjust the low range such as pedal parts and bass lines, MIDDLE allows you to adjust the middle range such as chords and melodies, and TREBLE allows you to adjust the high range such as leakage sounds and key click sounds, which was not possible with vintage Leslies. The sound can be tailored to suit venue characteristics and any individual instrument requirements.
Bass Out Terminal: If a more powerful bass is desired, the low range may be output to an external bass amplifier, subwoofer, or PA. via the [BASS OUT] terminal. The low-pass frequency may be adjusted with the [BASS OUT FREQ] knob. This sound is not “rotary”.
Overdrive: The new models are equipped with a new transistor preamplifier, based on the push-pull amplifier system used in vintage 330 model Leslies (and others). It reproduces the characteristic distortion of transistors when the sound is overdriven, providing “warmth” when applied lightly, or full rock and roll “scream” when dialed up. You can easily adjust this feature with the [OVERDRIVE ON/OFF] switch and the [GAIN] control knob on the bottom control panel.
11-Pin Power Remote Switch: Vintage Leslies did not have a power switch, they were activated when the Organ console was switched on. This behavior can be reproduced via the [11-PIN POWER REMOTE SWITCH], when the console is attached with an 11-pin cable.
Stationary Out: When these models are connected via the 11-pin plug to a Hammond Stage Keyboard such as the SkPRO; the Piano, Ensemble, and Mono Synth Voices appear here in Stereo ready to be fed to a keyboard amp or P.A. System. For Hammond Organs, the non-Leslie sound appears here.
Rotor Speeds: The rear nameplate can be easily accessed by removing the 2 thumbscrews. Underneath the nameplate are the controls to independently adjust the rise and fall times and the slow and fast speeds of the treble and bass rotors.
