Most of the modules are $199. I'm a Marshall guy and I would never go out and add a Boogie tone to my rig because I wouldn't shell out $1k plus used for that tone. But with an MTS I can get it for $199. A Vox type tone with my Marshalls? Impossible. A great Fender style clean with my Marshalls. Never going to happen. For $600 I can have a Rectifier tone, an AC30 tone AND a vintage Fender clean. I'm surprised anyone could complain about the versatility at that price. I can't buy any one of those amps used for what I can get all three of the modules for.
And Dave Friedman charges $600 to do the brown eye mod to a Marshall from what I understand. If I'm wrong I apologize to Dave in advance. If you are an MTS guy and also love modded Marshalls, this newest module is the biggest home run Lynch, Friedman and Randall have hit.
