VOCU is a Japanese boutique audio equipment manufacturer known for compact, handcrafted pedals, power supplies, and tape echo units. The brand name is an acronym for "Vivid Output and Capable Unit," and the company operates out of Japan with its products distributed domestically through retailers such as Sound House and internationally via the vintage and used market.

VOCU's catalog centers on space-efficient designs for pedalboards. Their tape echo line — notably the VTE-1600 and VTE-2000 — revived the slim-profile tape delay format, with the VTE-2000 also sold outside Japan as the Hiwatt Custom Tape Echo CTE2000 through a collaboration with Hiwatt. Alongside the tape units, VOCU produces the Baby Power Plant series of compact isolated power supplies, the Baby Volume Pedal (marketed as one of the world's smallest active volume pedals), the Magic Tone Room harmonic enhancer and filter, and the Magic Mic Room microphone preamp.

The brand has a niche reputation among Japanese boutique pedal enthusiasts and tape-echo collectors, with discussions of its gear appearing on forums such as The Gear Page and ModWiggler. Its tape echoes in particular have become sought-after on the used market due to limited production and the increasing scarcity of replacement tape parts.

Vocu has 2 products cataloged on Equipboard, including Effects Processors and Switch Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Electronic and Rock. Notable users include Aaron Dilloway.
