I have a zakk wylde overdrive too, actually they were both mine until yesterday, I'm not a metal man at all but zakks mxr overdrives sound so good with the gain low you get a really nice classic rock overdrive which is exactly what I'm after. However! I play through a clean amp, I've messed about with it before over a dirty amp and you can get some pretty heavy noises out it! I'd recommend it like, cracking pedals and built like tanks
