Sound&feature-wise it's great - you get four distinctive sounding classic phasers in one small box. My favourite settings are: phase 45 without script (good univibe sound) and phase 90 with script on (more pronounced, chevy phase but not over the top). Two drawbacks: 1. The pulsating diode on the left is ALWAYS on, even when the effect is off - it only goes off when you unplug the AC cable. 2. Depending on how you combine it with other effects in the chain, it may add a pulsating hi-freq whistle sound to your guitar signal, I suspect it has sth to do with buffer/bypass situation and that pulsating diode... - that's why I rate it 4 out of 5.
