A powerful partner for practice and performance, with a 10" True Blue High Headroom speaker and Bluetooth functionality.

The GAMMA 25 is a 10", premium-grade 25W guitar combo amp specifically designed with exceptional headroom, giving you superior sound, dynamics and clarity, as well as impressive volume from a small amp. It’s ideal for serious practice and low-volume performances. With its True Blue speaker, the Blue Channel (channel 1) provides a wide-open, all-analog clean sound that’s also the ideal path when stompboxes and multi-FX fully define your tone. A 4-voice channel (channel 2) delivers a full range of all-analog voicings from transparent clean, to dynamic mid-gain, and hardcore high gain tones. Meanwhile, Bluetooth and AUX audio inputs make it simple to bring in the sound of tracks and apps from your smartphone, computer or other devices. And it’s easy to switch between the two channels, using the front-panel button or by connecting your own latching footswitch to the rear-panel jack.
