This amp is really all we ask him, I'm using for a good dixaine year and is super reliable, the connectors are ultra complete, I bought it initially for playing music with strong volume and play the drums over and now I really use it for everything, a microphone, or two or three!, a guitar, a keyboard, as a return for a drummer or even for low (low volume because it Do not exaggerate!) this amp is really a great tool, a bit heavy but ultra reliable! the sound is very accurate and powerful! this is a really fun and practical product. when purchased it was costing around € 350 so really cheap but the quality is really waiting for you! This is an amp that can be used certainnement and that is really interesting for a group.
