Replacing with a Fulltone OCD
On paper this pedal has some great features, especially with being able to blend clean and overdriven tones and even use the clean side as a clean boost. I've used this pedal for about two years now, and I rely heavily on the volumes of my boosts, overdrives and distortions, as well as a volume pedal and my guitar's volume knob, to keep my 100 watt Mesa Boogie under control in a practice setting. However, since there is practically nothing on the Boogie's master volume between zero and 100, I'm stuck at either too loud or not loud enough for my distortions to get enough gain because the Sparkle Drive Mod can't compete in volume with my JHS Pack Rat mod or my Wampler Pinnacle Deluxe. There's no headroom at full volume and my Xotic RC Booster right before the Sparkle Drive can't give it any additional output. The RC Booster isn't an overdrive, but sounds better pushing the front end of the amp by itself. I gave a friend my Analogman tube screamer mod, but I wish I had it back, because it smokes the Sparkle Drive.
The TS-9 sounds are decent, but others do it better. The clean/dirty mix I've found isn't as useful to me as I thought it would be. It does start having some nice gritty breakup when I push it with the RC Booster. The stock TS-9 setting sounds too thin, but there are three more settings, each with increasing amounts of "modern" low end. The first bass boost is best, and you can forget the next two if you're not into that chunka chunka thing.
So yeah, maybe it's good for you, but it just doesn't play well in my rig. I would urge you to try it out first in conjunction with your other pedals and guitar or a close approximation. I have to wonder what some of the reviewers think about it down the road after they've lived with it a while and the new has worn off. I dunno, maybe it's me, or maybe it's you, Voodoo Labs Sparkle Drive Mod, but I feel like I don't even know you anymore. I thinks it's time to break up.
