J. Rockett Mr. Moto Trem-Verb

The Mr. Moto Trem-Verb from J. Rockett is a tremolo and reverb pedal in one box, pairing the two effects that vintage amplifiers carried together. J. Rockett describes it as "a very musical Tremolo with a super lush spring reverb as well"¹. The tremolo side goes from a very subtle throb to a choppy rhythmic pulse, and the reverb side aims at the classic, lush spring sound of an early amp².

The idea behind the pedal is rooted in amp history. As Delicious Audio noted when covering it, tremolo and reverb were the very first mass-produced non-gain effects for electric guitar, and their combination was originally found built into amplifiers over five decades ago²³. The Mr. Moto gathers both into a single orange box.

How the two effects work together

The tremolo and reverb sections can be run independently or together, so the pedal works as a tremolo only, a reverb only, or both blended at once²³. For reverb only, Pedal of the Day notes you can turn the Depth control all the way down and use the pedal on its own as a reverb³.

On the reverb side, the spring sound is the whole point. Delicious Audio describes it as sounding "like a classic and lush spring you'd find in a vintage amp"², and Guitar.com called it "a lush, warm spring reverb that, when blended together with the tremolo, is handy if you're trying to emulate a vintage Fender amp"⁶. The reverb has just one control, a volume knob labeled Verb²⁴.

Controls

The Wave knob is the tremolo's character control. Rather than offering fixed wave shapes, it blends continuously from a sine wave, which gives a smooth, rounded pulse, to a square wave, which gives the hard on/off chop associated with surf rock. On That Pedal Show, Mick and Dan described it as a pedal where "you can blend between a square wave and a triangle wave" tremolo, alongside a one-knob spring reverb⁷. Delicious Audio's 2023 guide likewise lists it as a tremolo with two waveform options and a fixed spring reverb⁵.

Pedal of the Day's reviewed setting gives a sense of how the knobs interact: Wave all the way left, Depth at 2 o'clock, and the reverb at 3 o'clock produced what the reviewer called a lush setting³.

The Speedswitch footswitch

The footswitch uses J. Rockett's proprietary Speedswitch system, which allows the part to be quickly replaced when it breaks². For a player who gigs regularly, that means a failed footswitch is a swap rather than a repair.

What reviewers said

Pedal of the Day reviewed the Mr. Moto positively, summing it up as³:

The reviewer found the pedal gave complete control over both effects overall, with the tremolo running from lush, beautiful tones to full-on surf rock³.

On That Pedal Show, Mick and Dan demoed the pedal as "a spring reverb one knob spring reverb and a three knob tremolo in one pedal"⁷, walking through how the tremolo's rate and depth knobs and the wave blend interact with the reverb level.

Where it came from

Press coverage of the Mr. Moto dates back to at least August 2018, when gearnews and Guitar.com both reported on the new J. Rockett pedal combining tremolo with spring reverb⁶⁴. Delicious Audio then reported it as newly unveiled in June 2022², and Pedal of the Day reviewed it that same month².

The Mr. Moto sits in J. Rockett's range alongside other vintage-amp-inspired effects, including the BOING Spring Reverb, a standalone spring reverb pedal.
