One Amp. Every Instrument. Anywhere You Play. Picture this: you've got a corner spot at the farmers market, your guitar, a mic, and absolutely no interest in hauling a gear cart. That's exactly the situation the Positive Grid Spark EDGE was built for. It's a 65-watt, 4-channel modeling combo amp and portable PA rolled into one compact unit—ready for electric guitar, acoustic guitar, bass, vocals, and keys, all at once if you need it. At just 13.6 lbs with a recessed carry handle and a tilt-back cabinet design, the EDGE is genuinely easy to transport. Set it upright for forward projection or tilt it back to use it as a personal monitor. Either way, the 120-degree sonic spread from the custom 6.5" woofer and 1" horn tweeter means your sound reaches the room, not just the front row. Whether you're a solo singer-songwriter, a busker, or someone who just wants one versatile amp that can handle rehearsal and a small gig without breaking your back, the Spark EDGE is worth a serious look. Four Channels, Zero Compromises Channel 1 is the guitar channel—it comes loaded with 36 amp models and 50 effects covering electric, acoustic, bass, and vocal applications. You get up to 3 pre-amp effects, 3 post-amp effects, and 1 amp model per preset, with 8 fully customizable presets stored on-board so they're accessible even without the app. Channel 2 is a dedicated input for vocals, bass, or acoustic guitar, with its own tailored amp models and effects and another 8 presets. Channels 3 and 4 are stereo ¼" inputs designed for keyboards, drum machines, or any other line-level source. Add in a dedicated music/Bluetooth channel volume knob on top, and you've essentially got a small band's worth of routing in a single enclosure. Connectivity on the rear panel includes dual XLR/¼" combo inputs for channels 1 and 2, stereo line outputs, MIDI in, headphone out, USB-C, and a DC input for the optional rechargeable battery. Players often find this kind of multi-channel flexibility especially useful for duo setups—one player on guitar into Channel 1, a vocalist into Channel 2, and a backing track device plugged into channels 3/4 or streaming via Bluetooth. Sonic IQ and the Spark App Ecosystem The EDGE runs Positive Grid's Sonic IQ computational audio processing, which uses a dedicated chip to handle dynamic range compression, bass enhancement, stereo widening, and auto EQ in real time. The result is a consistently clear, full sound that punches well above what you'd expect from a cabinet this size. Pair it with the free Spark app (iOS and Android) over Bluetooth or Wi-Fi and you unlock a much deeper feature set: AI-assisted tone generation, ToneCloud access with over 100,000 user-created presets, Smart Jam backing tracks, Auto Chords for real-time song chord display, a built-in 60-second looper, and over-the-air firmware updates without needing a computer. The onboard tuner with LED display handles quick stage tuning without opening the app at all. Battery-Optional Portability The Spark EDGE runs on AC power out of the box, but Positive Grid's optional rechargeable Spark Battery (sold separately) slots in via the DC input and delivers up to 8 hours of playtime on a single charge. That's a full day of busking, an outdoor party, or a campfire set without hunting for an outlet. The EDGE also supports footswitch control via the optional Spark Control X, which lets you switch presets, toggle effects, and more hands-free—useful if you're on stage and need both hands on your instrument.
