I just discovered this thread, and it's been very helpful (especially for understanding why the blend knob in the middle position sounds like it does). I bought a Thundergun about a month ago and have fallen in love with it. I intended it to be a backup for my MM Stingray but instead the Tgun has become the main and the MM has become the spare.
A couple of weeks ago I posted a review of my Thundergun. I'll probably pick up a Mercalli somewhere down the line... Or maybe a red Tgun... Or maybe both...
