My Unicorn came with a faulty tap tempo switch, so it went back. Despite that, some considerations:
- The vibrato (dry) mode sounds pretty good, the tone maintains its tonal integrity and the effect itself is neat.
- The univibe (wet) mode left me with mixed feelings. While the effect itself sounds gorgeous and expressive, the effect noticeably thins out the tone, taking off some of its low-mids/mids while boosting highs and deep throbby lows. Depending on your setup, this might be an advantage with distortion, as it will keep it from becoming too messy and muddy.
- The real bummer is that if you're using humbuckers or a hotter (boosted) signal before the Unicorn, the pedal will begin to clip in a nasty way. If used into distortion, the distortion itself will completely mask it off, but when using cleans it's pretty noticeable. This will only happen on the wet/univibe mode.
- Controls are very handy (especially subdivisions and volume knobs), but I would sacrifice the speed knob for a tone knob (as long as your Unicorn doesn't have a faulty tap tempo like mine did).
Buy, if you're use single coils exclusively. Don't, if you prefer humbuckers.
