The Trem-O-Matic is a floor version of the Vox Repeat Percussion module that plugged into your guitar, similar to the Dan Armstrong effects. It's been modified in 2 ways to make it better:

1) Added a Depth control to make it more versatile
2) Modified the output slightly to eliminate loss of volume

With speed settings from way slow to trippy helicopter, it's an excellent and choppy tremolo unit.

Expression pedal jack for controlling the Rate with a volume pedal is now stock on all Trem-o-Matics! You can really go slow with an external control if it has an output resistance of at least 100K.
