The Flatsons Crush 15 is a versatile 15W portable acoustic guitar amplifier designed for musicians who want quality amplification without being tied to a power outlet. With a built-in rechargeable lithium-ion battery, compact cabinet and carrying strap, it is well suited to home practice, rehearsals, busking, small performances and portable acoustic setups.

Powered by a 15W rated output with up to 30W peak power, the Crush 15 uses a full-range 5.5-inch speaker to provide clear, room-filling sound in a compact format. Its efficient Class D amplifier helps keep the unit lightweight while making effective use of the built-in battery.

The amplifier features two dedicated channels for flexible performance setups. The guitar channel is designed for acoustic guitar and other instrument sources, while the microphone channel includes independent bass and treble controls plus reverb for shaping vocal sound. Reverb can also be used with the guitar channel via the shared effect control.

Built-in Bluetooth 5.0 connectivity allows you to wirelessly play music or backing tracks from a compatible smartphone or other device. With an effective unobstructed range of up to approximately 15 metres, the Crush 15 can also function as a portable music speaker for casual listening and accompaniment.

The integrated 7.4V 2600mAh lithium-ion battery provides approximately 4–8 hours of use, depending on volume and operating conditions, while USB charging takes approximately 1.5–2 hours according to the supplied specifications.

Whether you're accompanying yourself with backing tracks, amplifying an acoustic guitar, singing through a microphone or performing outdoors, the Crush 15 combines instrument amplification, vocal input, Bluetooth playback and portable battery operation in one compact unit.
