Used Mission Engineering GM-IO Powered Guitar Speaker Cabinet 1 x 12

The Mission Engineering GM-10 Powered Guitar Speaker is a compact, studio-ready powered cabinet designed to deliver authentic amp feel without the bulk of a traditional guitar rig. This used GM-10 is in solid working condition, with light cosmetic wear consistent with normal use but nothing that affects performance. Built with Mission Engineering’s focus on accurate response and durability, it’s a great match for modern amp modelers and profilers, offering a clean, punchy platform that translates tones honestly at reasonable volumes.

In use, the GM-10 shines as a plug-and-play solution for players running devices like Kemper, Helix, or other amp modelers who want a reliable powered guitar speaker rather than full-range PA monitors. It handles everything from edge-of-breakup blues to tight modern rock tones with clarity and feel, making it ideal for home practice, rehearsals, and small studio setups. Balanced and unbalanced inputs make integration easy, and the straightforward controls keep the focus on playing, not tweaking.

At Music Go Round Aurora, we’ve been serving Colorado musicians since 2000, buying, selling, and trading quality used gear that players actually want to use. This Mission Engineering GM-10 Powered Guitar Speaker is available to check out in person at our Aurora location, or you can grab it online while it’s here. If you’ve been looking for a dependable powered guitar cabinet to pair with your modeling setup, this one is worth a serious look.
