Great Backup Amp for Gigs

Are you the kind of person who gigs regularly with combo amps? Chances are good that you will encounter an amp problem while playing a gig at some point in your life. However, that doesn’t mean you should bring along another amp with you for peace of mind.

Instead of replacing your main amplifier in the event of a failure, make use of the MicroBlock if a problem arises. Always have it ready for your gigs. Disconnect the internal speaker of your combo amplifier and connect this backup amp in place of it.

This way, you can proceed with your gig when running into trouble. Rather than hauling a redundant gear, use your combo amplifier as a loudspeaker cabinet if needed.

Headphone Out & Aux Input

By combining these two features, the MicroBlock 45 makes it easy to practice guitar routine. Before starting your guitar practice sessions, you need to hook up headphones (your output) and plug in a guitar as well.

Alternatively, you can pair this guitar amp with your smartphone using the aux input. Jam along with your band or backing tracks.
