Having owned a couple original Fulldrive 2's over the years the idea of a fulldrive 2 in a smaller footprint appealed to me. Since I cant afford a Fulldrive 3 [same size enclosure] I decided to spring for the Caline CC. I'm really happy with this one! In vintage mode it sounds just like the original to my ears. Vintage/flat mid/comp cut all effect the clipping in the same way as the original. I've never owned a 'mosfet' Fulldrive 2 and the mosfet mode on this one really changes up the feel of the drive. I'm prefering the standard mode but its nice to have the mosfet option. All the pots are tapered nicely and the build quality seems totally gig worthy.The boost works exactly like the original, adding more girth and grit to the overdrive without any huge jumps in volume.Pet peaves? Why do all the Chinese manufacturers put lock-washers on the outside of enclosures Anybody looking for a fulldrive or tubescreamer should check this guy out! I Got mine shipped to my door in Europe in 8 days here- http://www.donnerdeal.com/caline-cp-20-crazy-cacti-overdrive-guitar-effects-pedal-green.html While $80.00+ Mooer pedals are no longer a deal,$52.00 with free global shipping is a bargain for this one.
