Flower Pedals has unveiled the Sunflower Deluxe Tremolo, which the maker calls its most advanced pedal yet¹. The pedal is a stereo harmonic tremolo with a fully analog signal path and digital control². Guitar World reported it available now for $349 on August 5, 2022³; the maker's page lists a regular price of $349.00².

The circuit is an analog signal path with digital control, offering stereo harmonic and standard tremolo². It has 8 continuously variable waveforms across 3 modes, selected by a Shape switch: Sine mode blends between four sinusoidal variations, Triangle mode between three triangular shapes, and Random mode generates a random square wave whose complexity increases as the Shape knob is turned up². The Harmonic Width knob sets the phase offset between the treble and bass tremolo waveforms, and the Stereo Width knob does the same for the left and right channels². A secondary function of the Division knob sets separate speeds for the bass and treble components².

Tap tempo has selectable divisions, and there are three ramping modes: Momentary (hold to ramp to a second speed, release to return), Latch (tap to toggle between two speeds) and Drift (speed wanders with adjustable depth, speed and shape)². The pedal stores 5 onboard presets with a color-coded LED². MIDI is 3.5mm in/thru on Type A TRS with an integrated optocoupler, and there is a 1/4 inch expression jack with per-parameter mapping². Power is 9 to 18V DC center negative at under 200mA².

The maker describes the pedal as "a stereo harmonic tremolo pedal with a fully analog signal path"².

Accounts differ on the MIDI connection. The maker specifies a 3.5mm MIDI in/thru jack², while Guitar World described a 1/4 inch MIDI jack³. Delicious Audio, in a builder's notes section, also wrote of a "1/4? MIDI" connection¹.
