Positive Grid Spark GO Pearl White Modelling Combo

Positive Grid Spark GO PW — 5W Smart Modeling Combo for Guitar, Bass, and Travel

The Positive Grid Spark GO PW is a 5W ultra-portable smart modeling combo that fuses amp, Bluetooth speaker, and USB audio interface into a 346 g enclosure. Measuring 125 × 85 × 45 mm, it slips easily into a gig bag or sits on a pedalboard. Thanks to computational audio and a passive radiator, this tiny unit fills a room with detailed tone.

Computational Audio and a Three-in-One Design

What separates this amp from typical mini combos is its computational audio engine paired with a passive radiator, extracting more low-end than a 2" driver should deliver. The unit also functions as a USB-C audio interface (1 In x 2 Out, 44.1 kHz, 16-bit) and Bluetooth 5.0 speaker, allowing players to practice, record, and stream without juggling multiple devices. Smart Jam generates backing tracks; Auto Chords displays chords in real time.

Power Stage and Amplification — Small Watts, Big Output

Five watts through a Class D amplifier sounds modest, but the Spark GO PW makes every watt count. A custom 2" speaker and passive radiator push the maximum SPL to 82 dB at 1 m, providing enough volume for living-room jamming without distortion.

• Power Output: 5 W Class D — efficient amplification that keeps battery drain low while delivering headroom for clean tones
• This model features a 1 × 2" custom driver with passive radiator, extending bass response beyond what a single 2" cone typically produces.
• Maximum SPL: 82 dB @ 1 m — enough volume for bedroom and small-room practice sessions

Effects Engine and Signal Processing — 33 Amps and 43 Effects Onboard

The onboard DSP runs across two channels with 33 amp models and 43 effects covering noise gate, compressor, distortion, modulation, EQ, delay, and reverb. Players can store four fully customizable hardware presets for instant access to favorite tones, even without a phone.

• Channels: 2 — separate paths for instrument input and Bluetooth audio playback
• Amp Models: 33 onboard — boutique to modern voicings accessible without a computer
• With 43 effects (Noise Gate, Compressor, Distortion, Modulation/EQ, Delay, Reverb), the full signal chain fits in a pocket-sized unit.

Connectivity and Battery — Bluetooth, USB-C, and 8 Hours of Play

Wired and wireless options cover every scenario, with Preset selector, Music Volume, and Guitar Volume controls positioned on the top panel. A 1/4" input is ready for guitar or bass, a 1/8" jack serves as headphone or line output, and Bluetooth 5.0 streams from any device. The 2500 mAh battery recharges via USB-C in 2 hours and runs up to 8 hours.

• Bluetooth: 5.0 wireless audio streaming — pairs with phones and tablets for jam-along playback
• USB audio interface (1 In / 2 Out, 44.1 kHz, 16-bit) enables direct recording into any DAW without extra hardware.
• Battery Life: Up to 8 hours (2500 mAh, USB-C charging) — full day of practice between charges

Who Should Buy the Spark GO PW

Ideal for traveling guitarists, bedroom players, and bassists who need a backpack-sized rig that runs without mains power. Beginners benefit from Auto Chords and Smart Jam for learnable jam sessions; intermediate players have access to a recording interface and over 50,000 ToneCloud tones. Spark 40 or Spark MINI owners will find this model a perfect road companion.

Positive Grid — San Diego's Smart Amp Innovator

Founded in San Diego in 2013, Positive Grid set out to bridge mobile technology and the analog feel of guitar gear. The BIAS FX 2 modeling platform won multiple industry awards before the Spark series launched. Spark GO is the smallest expression of that vision: a 346 g enclosure running the full Spark DSP and ToneCloud library.
