Big Sound, Tiny Package — and a Battery to Boot
You know those moments when you just want to grab your guitar, sit on the couch, or head to the back porch, and play without dragging out a full rig? The Positive Grid Spark Mini was built exactly for that. It's a 10-watt stereo modeling combo that runs on a built-in rechargeable battery, fits in a backpack, and sounds genuinely big for something you can palm in one hand.
The Spark Mini packs 33 amp models and 43 effects into a cabinet barely larger than a smart speaker — all powered by Positive Grid's BIAS amp modeling engine. Four onboard programmable presets (Custom, Solo, Lead, Rhythm) mean you can dial in your go-to sounds and be playing in seconds without ever opening an app. And when you do open the Spark app on your iOS or Android device, a library of over 10,000 community presets from ToneCloud is waiting for you.
Whether you're a player who wants a quick-grab practice amp for the bedroom, someone who needs a take-everywhere tool for travel, or just someone who wants to stream music and noodle along without setting anything up — the Spark Mini fits the bill.
Stereo Sound From a Palm-Sized Cabinet
Two custom-designed 2" speakers are angled apart from each other inside the cabinet, and a passive radiator on the bottom handles bass frequencies in all directions. The result is a stereo image and low-end response that genuinely surprises people when they hear it the first time from something this small.
Power comes from a 10-watt Class D amplifier — efficient and clean, which is part of why the battery lasts as long as it does. Positive Grid rates play time at up to 8 hours at mid volume or lower, and the amp recharges in about 3 hours via USB-C, compatible with most standard mobile chargers you already own.
More Than a Practice Amp
The Spark Mini doubles as a USB audio interface — connect it to your computer via USB-C and you have a 1-in/2-out recording setup ready to go. It also connects via Bluetooth 5.0, so you can stream music from your phone and play along through the same speakers. The 1/8" headphone output lets you practice silently, and there's a 1/8" aux input for wired connections as well.
The Spark app (free for iOS and Android) adds a lot to the experience: Smart Jam generates live bass and drum backing tracks from your playing, the Auto Chord feature pulls real-time chord charts from songs you're playing along to, and you can slow down or loop sections of tracks for focused practice. Spark Control wireless footswitches are sold separately and are compatible with this amp for hands-free preset switching.
