The problem is not in the distortion pedal but rather in the fact that you want to sound like Panic at the Disco.
Distortion before the zoom. Unless you want to use just the compressor and noise reduction from zoom then to distortion pedal, but then any modulation effects will sound weird.
Roger Mayer invented the fuzz box, the earliest form of distortion pedal.

The Boss DS-1 Distortion Pedal is an all-around good piece of equipment. Although it is on the inexpensive side, it still produces a solid tone that can be dialed-in with your amp to get everything from a lightly crunchy overdrive to a higher-gain distortion. Kurt Cobain and many others have used the orange pedal as an additional overdrive box to supplement their amplifier distortion. It will work as well with a Peavey amp as it will with anything. What it really comes down to is your own taste. As with any pedal, it will combine its own tones with the amp's sound to produce the final distortion tone. Either way, it's a good pedal (especially for the price) and it's worth experimenting with.
