The LSD is a recreation of the vintage uni-vibe units but with modern applications.
if you want a deep throb, that doesn't lose volume, and with the option to select 3 different tone types via a rotary switch, this is the one for you!
these modifications to the univibe make the LSD one of the most versatile univibes on the market.
 
 
The LSD has 4 controls:
 Speed, which controls the speed, which you can follow with an indicator LED to help you set the ideal speed.
Depth, which adjusts the amount of effect that is added to the signal.
Loud, adjusts the output volume of the pedal.
Tone is a rotary switch to choose between 3 different types of univibe, 
and a classic two-position selector to choose between chorus and vibrato.
 
 
The LSD can be powered by either 9V batteries or power supplies.
possibly the only univibe on the market that has LDR photocells and is powered by 9v! so you don't need an 18V output on your power supply.
It uses 2.1 boss type barrels, with negative center, and to avoid noise and leaks, it uses an Isolda power supply. if you don't use an isolated power supply, this noise/oscillation could leak to the other pedals even when the pedal is off. please avoid the daisy chain.
