Greetings, Except for some initial reviews online when the MV50 line was first released there is not much info out there. I purchased the MV50 AC in August of 2017 and it has been my main gigging amp since. It replaced my Roland Cube 80XL which I still use occasionally. I like to use different cabs depending on the gig. I'll use a 4Ω cab if I need 50 watts or an 8Ω cab if I only need 25 watts. For effects I actually use a Zoom G1on , a hugely underrated and powerful Fisher-Price looking multieffects. I use it strictly for effects, no amp or cab models cause the Vox just sounds so good besides running an amp model through a guitar amp never sounds good to me.
