The Silver Cloud is an original Komet design. I copied a response from Hogy the designer on TGP about the amp below that might help. I never believed the Komet hype until I got one (low power K60). They are amazing amps and I use the K60 amp in the III the majority of the time.
From TGP:
This is basically an amp that I designed for myself, initially. I've been playing and gigging with vintage amps for decades, and I still have quite a collection of old amps. I wanted an amp that has that vintage feel and gain level, without the shortcomings that bug me in the old amps.
My favorite vintage amps are indeed a 1963 JTM45 I've had forever, a 1963 Vox AC30, and a 1960 Tweed Bassman. A 1965 AC100 that sounds HUGE also needs to be mentioned here.
The Silver Cloud is not a copy of any of those amps, but it is founded in those classic tones.
The preamp follows a classic topology all of the above mentioned amps share, but with a very different tone stack and very finely tuned frequency response.
The power amp is pretty unique, I'm running a pair of cathode biased KT88 pentodes in Class A, with no negative feedback. This gives me a very harmonically rich response that seamlessly transitions into overdrive. It's one of those things where you almost can't tell whether you're playing clean or overdriven, it sounds like both. Clean tones that sustain and turn over into harmonics.
There is a control in the preamp I call "TSB" (Tone Stack Bypass). Turning it up gradually routes the signal around the tone control section. Since the tone stack is subtractive by nature and has inevitable insertion loss, bypassing it ups the gain, midrange and harmonics.
The Silver Cloud produces about 55 Watts. With P-90s or humbuckers, significant overdrive starts around 10:00 o'clock on the volume with the TSB off. 11:00ish with Strats and Teles.
Like all Komets, the amp is very sensitive to input levels, so you can much higher headroom by turning down the guitar's volume. It is a very tactile amp that really responds to the player's input.
The Silver Cloud has tremendous, clear bass response due to the KT88s and the big (18lb of steel), proprietary output transformer. Midrange is very vocal and detailed, trebles are chimey yet warm. It's a big, fat, round, clear tone that really let's the guitar's character come through.
I have been gigging the prototype for over three years, constantly tweaking and fine tuning details until I was satisfied that the amp was truly finished.
The feel of the amp was as important to me as the sound. This is an amp that feels great under the fingers. The response is bouncy, never harsh. Very euphonic.
Being proud of it, I'm obviously biased, but I'm also being completely honest when I say that for what I like, this is the greatest amp I have ever played. Hands down my favorite, and the one I could replace my entire collection of amps with (which, thankfully, I don't have to do).
