Re: Rocktron Silver Dragon?
I don't have the Silver Dragon, but I have 25 distortion pedals. I don't claim that having a lot of fuzzers makes me an expert, but it gives me the oportunity to compare side-by-side. Overall, my 2 favorites are the Boss Mega Distortion and the Keeley-modified RAT. Both do heavy distortion really well, and both of them clean up nicely. The MD-2 gets heavier, but I keep it in "rock-distortion" terretory with customizable bass response. It effectively covers everything from dirty boost to crushing metal distortion, and it sounds awesome with both solid state amps and tube amps. It just doesn't do a fuzz tone convincingly. The RAT doesn't get as heavy, but it gives those fuzz-like overtones, and it articulates better than a Muff, even at heavy distortion settings.
In the Rocktron group, I have tried the Metal Planet, and I own the Zombie. The Zombie sounds great, and I like having control over the symmetry of the distortion wave shape, but I wish I could turn the fuzziness down on it. I usually don't play with that much distortion. The cool thing about the Zombie is that they describe this gimmicky "psychoacoustic 3-D" sound with variation of the "Stare" knob, but it actually works.
