Very Good Condition
Keep in mind that this is a one of a kind Hand Made, Hand Wired pedal. It will have inherent visual blemishes. Velcro attached on back. It has been tested and is fully functional.
Description
The Apollo Tremolo is a highly advanced version of one of the most popular music effects ever made! Based on the original Tremulus Lune version, the Littleman Apollo adds a SPEED SHIFT for a dramatic change and a “KILL SWITCH” to remove the effect while maintaining a high quality buffered throughput.
Controls
Gain – Adjusts the overall level to keep the Tremolo at Unity Gain or otherwise
Speed – This adjusts the rate of speed of the Tremolo waves. Use this in conjunction with the Speed Shift
Speed Shift - Switch [SW1] - The speed shift switch allows you the option of kicking an extra capacitor in parallel which has the effect of changing the speed range of the LFO circuit. This option adds more flexibility
Depth – Adjusts the overall strength of the Tremolo sounds
Spacing – Adjusts spacing between volume pulses
Smooth – Blend between full on/off square wave "chop" to smooth buttery sine-tri-round wave
Requires a 9vdc Center Negative Power Supply (not included)
Components
The NSL-32 Vactrol consists of an LED and a photoresistor. As the LED changes intensity, the photo resistor changes resistance. This change in resistance is what manipulates the audio signal to give us a tremolo effect
