Quaverato Harmonic Tremolo Pedal combines many features to make a great sounding, versatile, and practical stompbox. Available as a DIY KIT or Ready-to-Play. Full MIDI implementation available as a kit option; standard with Ready-to-Play.
Digitally controlled, all analog signal path combining maximum flexibility with great tone.
Both Traditional (In-Phase) and Harmonic (Out-Of-Phase) Tremolo modes
Up to 15dB of gain
Modulates the high and low frequencies independently for dynamic swirling effects
Extra internal controls allow for custom crossover frequency selection and individual HIGH and LOW signal path volume adjustment, for full tonal control
Bypass footswitch can be used as either a toggle or momentary switch
Plus all the usual:
LFO wave shape, rate, depth and spacing (aka wave form shift or duty cycle)
Tap Tempo footswitch and multiplier selection
Relay controlled, true-bypass switching with Click Suppression for Silent Switching
MIDI implementation gives remote control over every feature
Harmonic Mix allows the HIGH and LOW frequency bands to be modulated independently
Adjustable harmonic crossover frequencies and individual volume controls for the HIGH and LOW signal paths for tonal control — the Quaverato can be adapted for use with guitar or bass
Relay-controlled true-bypass SILENT SWITCHING
Boost up to 15dB
Tap time with multiplier: 4:1, 3:1, 2:1, 1.5:1, 1:1, .5:1
Footswitch can engage the effect either as a toggle or as a momentary switch
All the usual LFO waveforms and controls: speed, depth, shape, and spacing (aka waveform shift, or duty cycle)
Full MIDI implementation standard on built units; optional with DIY kit
Sturdy 18 gauge steel enclosure
Robust polycarbonate label
Open source software so all you hackers can customize your tone!

What You WIll Need
Here's what you will need to build the Quaverato Harmonic Tremolo Pedal KIT. See also the online Quaverato Assembly Manual, available on the Documentation tab.
NOTE: If you are upgrading an existing Quaverato with the new MIDI Mod, you will also need a USB-Tiny programmer and the free ZDL Updater to install new software.
#2 Philips screw driver
Small flat-head screwdriver
Needle nose pliers
Small diagonal-cutting or flush-cutting pliers
X-acto knife or hobby knife
8mm, 10mm, and 5/8” sockets and driver; in a pinch, pliers may work as well.
Soldering iron (not a soldering gun, or a “cold heat” iron), good quality, 15-50 watt. An iron with a temperature control and a stand is best. Use a small or medium size tip, with conical or chisel shape.
Solder sucker or solder braid (optional, but very handy if you have to remove or repair any components!)
Damp sponge or dry solder-cleaning pad
Clamp or vise to hold the printed circuit board while soldering (optional, but handy)
Solder, 60/40 rosin core, small diameter
Rubbing alcohol and cleaning rag
Transparent tape or masking tape
9V DC center-negative supply, at least 200 mA -- typical pedal supply
