I've been searching for a small pedalboard friendly sized expression pedal to replace a borrowed Hotone Wah/Volume/Expression. This is about 5mm longer than the hotone and the same width (when taking in to account the jacks on each side of the Hotone). It has the identical height and travel as well. It's about 10mm thinner and lower than my Dunlop mini. Both those pedals also have other functions besides the expression (which I don't need) and run at 2-3times the price. The EXP001 is not quite as tall as other similarly priced expression/volume pedals available online. It's solidly built but still very lightweight. It has a stiffer resistance than other pedals I've used, but I quite like that.
When I first plugged it in I had an issue with the full sweep happening in the lower 20% of the pedal. But this was easily resolved by swapping the Tip & Ring connection on one end of a TRS cable. It now works perfectly, and has a nice sweep/taper/resistance. The pedal is advertised as potentially only reaching 95% of the sweep, but I've found that it seems to go the whole way perfectly without any adjustments.
The packaging is almost Apple level slick. I ordered mine directly from MeloAudio and received a generous discount. I was shocked that it arrived on my doorstep in Australia via AmazonPrime only about 30 hours after placing the order (in USdollars with a Chinese company). I've NEVER had any product ordered online delivered that quickly. Superb product and service. Couldn't be happier.
Sidenote: It has 4 rubber feet glued on the bottom and 6 small protruding screws. I want to attach it to my pedalboard with velcro. The rubber feet are very firmly attached but easily removable and the screws pose no problem once the velcro is attached as with some other mini expression pedals I've considered. At this price I'm tempted to buy a second one and sell my Dunlop
