Here's a little something to get you even more hyped :-D

http://www.quinnamp.com/sdodescription.htmDumble amp types
Vintage is one of the older types of this style of amp. A bit more rooted in the raw Fenderish tone. This is the amp that established the legend. It can sustain like a mofo! It is a singing OD for sure. Not much compression, very touch sensitive and dynamic....
Skyliner I (low plates) (#124) is a variation of the above. A new tone stack is used. It is a little less Fender but still a somewhat lower gain affair. That is to say it is very touch sensitive and it requires a dynamic hand to control the amp. Most people like to set the gain low and push the power amp, rather than cranking the gain and trying to dynamically reel it in. Either approach will work but I think this amp likes the pushing more than the reeling back. It has the same gain as the vintage amp but the new EQ is more "signature Dumble" and a little less Fender. Improved cleans from the Vintage model. It still sustains like a mofo, has a bit better string to string definition and is a little more refined in the tone shaping.
Ceriaton OTS = Skyliner II (High Plates) has more headroom, definition, and punch, more lively and responsive clean sound, smoother OD, and a small bit of compression, very touch sensitive, with lots of sweet singing tones.
HRM Skyliner II contains a second tone stack just for the OD channel. It is more or less a Marshall style tone stack this allows tone shaping of the OD independent of the cleans. Smooth as silk, goes from clean to mean and transition between the two is amazing. You can pick clean, a bit dirty, grinding, soaring, all with your hand and all smoothly with definition. No rasp or buzz. Very refined sound with gorgeous smooth tones. A little more compression that the above amps but not in a bad way. Very natural with a dynamic response, that is second to none. This amp feels like it breathes with you after awhile.
Smooth singing overdrive, completely dynamic, never any rasp or buzz, no IM distortion or other uglyties. This is so far the most requested one and the amp I could not be without. It's smooth but never bland.
Bluesmaster Think raw early Fender/Marshall tone on steroids. The tone stack is decidedly Bassman territory, however because of its Dumble genes, and many other differences, it is far better. The clean is the best cleans I think I have ever heard, in a Dumble or otherwise. The clean sound will sing and sustain!!! The OD is much less smooth and much less compressed than the above amps. It has some early Marshall vibe to it. Boosted cleans with this amp are to die for. The OD is a bit more raw and edgy then some of the other offerings but with boosted cleans you get the smooth side of things and with the OD you have a less polite and refined tone. Lots of punch, sustain and singing but not as smooth as some of the other offerings. This one can be thick and dense too. Not dark and crappy, just "meaty"...Open clean cleans to mean and a little rude. It is a big, fat, blues machine with lots of character or soul, which can play nice but still stomp in the dirt. It has a HRM post OD tone stack which gives a little more tone shaping and refining in the OD section.
