The Japanese Butter Roll Vibe is a mini-sized pedal from Effects Bakery that combines the sounds of a Univibe and a rotary speaker in one small enclosure. It runs three modes, Vibe, Vibrato and Rotary, so a single footswitch-sized box can cover the undulating, swirling territory usually split between a dedicated vibe pedal and a rotary effect1.
What it does
The pedal's three modes let you switch between Vibe, Vibrato and Rotary sounds. RockBoard's PedalPedia describes the range as "a range of undulating and twisting tones," and suggests two ways players put it to work: with a fuzz pedal to recreate a vintage psychedelic sound, or applied subtly to a clean tone to add movement1.
Because the circuit is analog, it sits alongside other analog vibe and vibrato designs rather than digital modelers. If you are comparing it with other pedals in this territory, it overlaps with both dedicated vibe pedals such as the Fulltone Custom Shop Mini DejaVibe Mk II or JHS Pedals Unicorn V2 and pure vibrato pedals such as the TC Electronic Shaker, as well as rotary-flavored designs like the Dunlop Rotovibe. See the full range on the Vibrato Pedals page.
Power and practicalities
The pedal runs on 9V DC, center negative, and draws 17.5 mA1. Its mini-sized footprint is aimed at players squeezing a vibe onto a crowded board.
