It seems like most of the Dumble and other customizations are being done to Blackface amps, but you don't see a lot of Tweed or Brown amps with things like... Reverb Master Volume Additional Gain Stages Midrange Controls I know people tighten up Tweeds or add bigger transformers (Tungsten and the like). I also know that they do add-on reverbs. But, that's not what I'm talking about. When was the last time you saw a Tweed faceplate with a reverb, master, or mid control built in? It's the same with Brown amps. Sure, there's the VibroVerbs with reverb. But, no one has done it to a Brown Deluxe. Or have they? I know Red Plate and some other companies have EQ's with Brown and Tweed settings, but what else is out there? Please post links to companies that are doing custom Tweed and Brown based amps... Thanks!
