Behringer UV300 Ultra Vibrato

For the sound alone, this pedal comes highly recommended, as it simply sounds excellent. If you haven't already, go watch the comparison video with the coveted Boss VB-2 on YouTube, made by JHS Pedals; they sound identical, and even share the same bypass features selected by the Mode button, which are just as useful as they are fun.
Unfortunately, the plastic housing and overall cheap feeling choice of materials does not support the great sounds found in this unit (hence the very low price), which over time may or may not cause functionality issues.
Also, the Rate of the vibrato effect does not get as slow as I would've have liked, which is the only reason why I parted with it after a short while. If you don't need it to be super slow, and don't stomp it violently, this effect box can provide you sweet vibes.
