"I want to enjoy the guitar more casually at my desk or in the living room."
"But I don't want an amp so small it sounds thin and empty."
The Positive Grid Spark MINI was built by working backward from how different people actually live with the guitar.
Don't let its cute looks fool you. This is a small guitar amp with a "huge" sound, fitting beautifully into Japanese living spaces and daily life.
A size that disappears onto your desk
Spark MINI was designed to blend quietly into your personal space — a work desk, a bedroom, the gap on a bookshelf.
Its compact body stays out of the way of your room's decor, while precise acoustic engineering produces surprisingly clear, deep stereo sound.
Its standout feature is a "passive radiator," discreetly built into the base. This mechanism completely cancels out the thin sound typical of small amps, filling the room with a rich, satisfying low end.
Tone-shaping made effortless with the app
The amp itself only needs minimal volume adjustment and preset switching. All the detailed tone-shaping and practice happens on your phone's app.
The moment you think "I want to play that song right now," there's almost no barrier to actually making sound — creating the best kind of loop, where you pick up the guitar in a spare moment and suddenly hours have passed.
A lifestyle with music, no boundaries
With a built-in rechargeable battery good for up to 8 hours, Spark MINI is portable enough to bring along on a quick outing or a trip, not just around the house.
Use it as a high-quality Bluetooth speaker for streaming your favorite music day to day, then pick up your guitar whenever the mood strikes and start a session, seamlessly.
Flexible enough to handle electric, acoustic, and bass all in one unit. A companion that quietly stays close to your life with music.

Product Info
A portable amp that quietly blends into everyday spaces — a work desk, a bedroom shelf, wherever life happens.
Small enough to sit unobtrusively in your living space, yet a passive radiator (a bass-boosting mechanism) on the bottom fills the room with a sound richer than its size would suggest. Day to day it lives alongside you as a fine Bluetooth speaker for your favorite music, and whenever the mood strikes, you pick up the guitar and slip seamlessly into playing. A well-sized companion that comfortably blurs the line between music and everyday life.
