No question, the Zendrive nails that Dumble ODS sound. I love my Zendrive with 'buckers. It absolutely kills
with my ES-339!
OTOH, with my Strats I actually prefer the FET dream (cepedals.com) because IMO it seems to mate up better with the sound of singlecoils and it's more versatile than just the Dumble tones (due to the "girth" knob). YMMV.
I'm slowly developing separate signal chains for the Strats and Gibsons, but if I could only have one Dumble-type pedal on the pedalboard, the Zendrive would be it.
