I'm not big in to effects. I have a Zoom 607 Multi pedal (for sale BTW). The Zoom has one particular effect that I really like. The effect that I like is listed as a Tracey (british famous amplifier sound) and the corresponding pedal is identified as Gain. This is pretty much the only effect that I use on the Zoom (hence why it's in the classifieds).
My question is this: what single pedal/box would give me this effect? It fits nicely with my guitarists tone, but the Zoom can't hold up at the higher volumes. May be operator error

, but I'm looking for a single pedal nonetheless.
Thanks!
