You hear time and time again how Non MV amps go from clean to scream with just the volume on the guitar better than MV amps. This is simply NOT TRUE! A MV lets you set the overall MAX VOLUME you need, then you adjust the gain from there. I took a Dumble ODS, a Trainwreck express, a Komet 60, a Bogner Shiva 6L6, a TwoRock Emerald Pro, and a TwoRock Opal and checked them SPECIFICALLY for this. NONE did it any better than the other. They were all about the same. Here is a clip of my Fuchs ODS doing just this. The guitar is a Fender hollow USA Tele. Straight into the fuchs. I cranked the gain up about 1\2 way, then turned the volume on the guitar down until it cleand up. There is no cap on the guitar to keep the highs when you turn it down, but it still sounded fine to me. To make it REALLY cool, the Max volume was still at house practicing volumes. I could obviously turn the MV WAY up to allow even more clean headroom. This goes to show how muck flexibility the MV gives you. Try THIS on a 50 watt Non MV amp! You will blow your ears and neighbors out! Anyway, I play a few open chords and strings, then just turn up the volume on the guitar and let it RIP! Totally not my style, but it WORKS.
