Well to get back on track. I like DG and own a B7k, VMT and Duality that Doug did a great mod to. I have had nothing but good experiences with Darkglass and would gladly recommend their products to people looking for that kind of sound. That said, I do not think that the VMT is a good pedal to cop a tube amp being pushed into overdrive. I haven't owned every tube amp ever made and make my judgement based on 3 SVTs, a vr4 and a few traynor amps that I have had access to over the years. I enjoy the VMT's drive and I should use it more (it's been on the shelf for a bit). But it doesn't sound like a tube drive at all and I often wonder why Darkglass uses the title they do. For a tube drive sound I would recommend the Fairfield Barbershop. I also like the Azure Drive, Bearfoot/BJFE Blueberry (but it is a little dark for some), the Honey Bee is a clearer example than the Blueberry and even can get a good tube sound from the Dunwich Volt Thrower on no-clipping with lowish gain.
