The pedal plays great, depending on your amp it might sound better either in the front or in the FX loop as a preamp, try both and see how your amp reacts to each one.
You get channels 3 and 4 from the VH-4 amp and they really sound great when i plugged it into a marshall tube amp, I mostly stick on the 3rd channel because i hardly ever play leads anymore but that 4th channel has enormous amount of gain on tap for leads.
The only thing that's "bad" about it is the loud click switches, i like the soft ones more, but that's hardly a complaint.
