Good Vibes Univibe : Does a fine job - buy it.

This is an affordable and reliable vibe pedal that can enhance your heavy lead tones when used with fuzz a la Hendrix or give a dreamy wash to your clean chords a la Pink Floyd.

I only have it a week and am still experimenting. The effect can be quite different depending on where you place it in the chain. I started with it before everything and it sounded pretty good. Behind the fuzz pedal however, it loses a lot of volume and perhaps some tone fatness, but it more closely approximated the Hendrix sound I was chasing so it will stay there for now.

The vibrato doesn't appeal so much to me but it does what it says on the tin. The chorus is quite good. I didn't care to have the speed and intensity settings beyond 12 o clock but if you are looking for weirder sounds you may prefer to push further. I wouldn't dismiss this pedal simply as retro - there is potential there in conjunction with other pedals to go and make something really new and unique.

You can add another dimension again with an expression pedal, allowing you control with your foot over the speed or intensity of the swirl (not both simultaneously obviously). Getting the appropriate power supply included is good and Boss could take note!

I'm afraid I can't do comparisons with other models beyond what I hear on youtube. I'm satisfied that this one delivers what I wanted.

Conclusion: This is a win for EHX and I recommend it as a great arrow in the quiver that you certainly won't use all the time but will always need it at some time. Buy it.
