I was set in just going in and out of the store with just the Apranoid as a noisemaker pedal. But the store also got me to try out the Meris Hedra. Trying them back to back, they're not remotely the same but, I did enjoy the Hedra with all the ridiculous sounds it can produce. The most fun was I had was turning them both on for pure dissonant carnage. But ultimately, I just wanted the Arpanoid (but I may get the Hedra down the line...).
All told, the fixed arpeggios makes this a difficult pedal for musical uses, unless you want to recreate something like Pink Floyd's On The Run, Ween's The Mollusk or Tim Folin's Solstice/Equinox soundtrack. But it certainly begs to be plugged into odd synths and process noisy fuzzy tones. At it's most conservative settings it can create some cool detune sounds.
Not something I'll use regularly for a live rig, but definitely be a fun post production tool.
