You can dive into the world of innovative sound creation with the Crash Pad Analog Drum Synth Pedal, a high-quality reissue of the original drum synthesizer pedal from Electro-Harmonix. This advanced musical tool, part of EHX's distinguished line of analog drum synthesizers, is designed to generate a wide spectrum of drum sounds and other-worldly oscillation sweeps, just like its 1980 predecessor. The Crash Pad is more than just a drum synth pedal; it's a versatile instrument that can process external sounds through its resonant filter, opening up a universe of sonic possibilities. This durable pedal has been updated to respond to expression pedal/CV input, allowing real-time external control over the filter for a more dynamic performance.The Sensitivity Button on the Crash Pad controls the sensitivity to an external trigger, offering high sensitivity in the down position and low in the up position. The Start and Stop Knobs set the starting and ending points of the frequency sweep, while the Time Knob controls the duration of the sweep from the start frequency to the stop frequency.The Resonance Knob adjusts the resonance (or Q) of the low pass filter, and the Volume Knob controls the output signal's volume. The Decay Knob activates an internal volume envelope each time the Crash Pad is triggered, setting the time it takes for the volume envelope to fade out the triggered sound.The Crash Pad also features a Push Button Trigger, located at the center of the logo, which can be used to create amazing sounds. The pedal is equipped with a 1/4" Output Jack for the audio output, an Ext. Trig Jack for an external trigger input, an Aux in Jack for an external sound source, and an Exp. Ped Jack for connecting an expression pedal with a TRS plug to control the filter sweep with your foot. Experience the versatility and high-quality sound of the Crash Pad Analog Drum Synth Pedal, a reliable and innovative tool for any musician looking to explore new sonic landscapes.
