Diamond Analog Optical Tremolo and Chopper Pedal

Going beyond your typical trem, this versatile Diamond pedal lets you dial in old-school amp-style undulations or warp your signal with edgy chopper effects.

Tremolo has been a staple effect since the '60s. Now it's time to welcome it to the 21st century. Don't let your preconceptions fool you, this is not your average trem. Combining 3 distinct trem flavors into one pedal, the Diamond Tremolo takes what it means to be a tremolo and pushes it well beyond the limits. At its core, the Diamond Tremolo offers classic amp style, optical amplitude modulation with sine, shark fin, and square waveforms. Further enhancing the pedal, a modern FET chopper delivers a sharp edge, completely killed, tremolo effect and a Dicer mode allows you to arm the pedal and use it as a momentary kill switch. Include the 11 rhythm control positions providing a number of different depth, mode and tempo accents and the updated Diamond Tremolo will be your go-to tone warping machine.

A Modern Standard
For the modern pedal-user's needs. Space saving design, without any loss of quality. All analog, Burr-Brown audio path with microprocessor control. Complete with top-mounted jacks and relay based true-bypass switching.

Momentary|Latching Mode: The INSTA-CHOP and DOUBLER can operate either in:
- Momentary: only on while its footswitch is held down.
- Latching Toggled on and off when the footswitch is held down.
Hold down the ON|CHOP or TAP|DBL footswitch during the entire LED power-up sequence to change its respective operation.

GEEZER MODE: It wouldn't be a Diamond Tremolo without the classic tremolo effects. No frills, just pure undulating goodness. Geezer mode disables the secondary footswitch for those seeking maximum simplicity. Hold the TAP|MODE toggle switch down during the entire LED power-up sequence to engage this setting.

Depth and Duty: this pedal stores 3 DEPTH knob settings: normal depth|duty, INSTA-OPTO depth, and INSTA-CHOP duty. To change one of these values, the pedal must be in that state and the depth knob must be adjusted - in momentary mode, hold down the CHOP footswitch while adjusting the depth knob.

DICER MODE: 11th Position On Rhythm Knob: Turn the TAP|DBL footswitch into a killswitch by engaging the CHOPPER only while its pressed or held down. As such, there is no tap tempo or DOUBLER in this setting: set the speed and duty cycle using their respective knobs/ Rhythmic patterns also can be selected by simultaneously holding down the TAP|DBL footswitch and turning the Rhythmic control to the desired pattern.
