I've had the PF 15R for a little over a month. Compared with the PF, which I'm playing clean, the Vox model in my Zoom G1 Four multieffect pedal sounds flat. And I had thought the Zoom model sounded pretty good before I got the PF! A lot of things are like that, I've found. You don't know what you're missing till you've had it for awhile. Of course, the opposite happens too: you don't know how good you had it till it's gone. Using the PF in combination with the Zoom's effects works quite well. I'm mostly using the Zoom for compression and slapback delay; or, to simulate a 12-string for "Turn! Turn! Turn!," compression and a 10-cent detune.
