INTRODUCTION
Thank you for purchasing a Diamond Vibrato pedal. This analog design offers a true
vibrato effect - pitch modulation rather than the amplitude modulation commonly (and
incorrectly) referred to as vibrato but which is in fact, more accurately described as
tremolo. The two effects sound distinctly different from each other and you will instantly
hear the difference when comparing the two.
In addition we’ve included the capability of mixing a variable dry signal with the pitch
shifted signal for a wonderful sounding chorus!
We hope you’ll enjoy using this pedal as much as we have enjoyed designing it.
Remember to protect your hearing and wear appropriate hearing protection when playing loud…
DESIGN BACKGROUND
The Diamond Vibrato design began as an idea in late 2006 to produce an analog, true
vibrato pedal designed around the MN3007 bucket brigade device. The design has gone
through numerous design and feature set changes since that time with various form factors prototyped, experimental controls added and removed before arriving at what we
consider the ideal balance of ease of use, simplicity and flexibility.
Many of the features of the Diamond Vibrato are based on feedback from players just like
you... thank you all!
