Positive Grid Tremolator pedal is available under the Drive effect group and is inspired by the Demeter TRM-1 Tremulator
The Demeter TRM-1 Tremulator is a tremolo pedal which has been manufactured by Demeter Amplification since 1982. It was apparently designed at the request of guitarist Ry Cooder, who wanted a pedal that sounded exactly like a vintage Fender tremolo unit for use with any amp.
The Tremulator has 2 knobs, which are, from left to right:
- "Depth" (controls the amount of amplitude modulation on the signal or the amount of effect)
- "Speed" (increases and decreases the frequency of the low-frequency oscillator)
There is also a trim pot on the side to set the bias for the optical unit, and the unit comes preset at Ry Cooder's preferred settings.
Notable musicians who have used the Tremulator include:
- Jonny Greenwood of Radiohead (can be heard on "Bones" and "Lucky")
- Nick Valensi of The Strokes (can be heard on "Juicebox")
- Eddie Van Halen of Van Halen
- Eric Clapton
- David Gilmour
- Lou Reed
- Nels Cline
- Sonny Landreth
- Ben Harper
- Ry Cooder
- Tommy Emmanuel
- Michael Weiss
- Scott McKenzie
- Jamie Marshall
- Oz Noy
- Michael Landau
