This is without question the most fun I've ever had with a pedal—just pure, unadulterated fun.
Ever since I first heard Tom Morello's solo on Killing In The Name back in the mid-'90es, I've wanted to have a Whammy. Since then I've seen numerous others, including MonoNeon and Thundercat, use it, so the desire to have one blushed back up now and again.
Now, some 25 years after first encountering the pedal I finally realized that it's perfectly alright to buy a pedal just because it's fun, so I did... Even if you're not necessarily producing anything useful with it, just fooling around doing wonky stuff is absolutely worth the price. Not to mention finally living out the dream of playing the solo from Killing In The Name correctly. My 14-year-old self would have been absolutely awestruck. Money can totally buy happiness.
Only minor annoyance is its pretty aggressive power consumption (1300 mA). It's not likely that your existing power supply on your pedal board will be able to power it. But apart from that, the build quality is top notch, the pedal feels very robust and it doesn't feel like they've skimped on anything building it.
You'll need to use your hands to change program on the program dial (unless you set up midi to control it), so unless you stick to one setting, then you'll be reaching down pretty often.
Other than that, it's smooth sailing. Obviously, since it's a modulation pedal, it has a few tracking issues now and then, but I figure that's impossible to avoid when modulating in real time.
