..but these do cost a lot more than this one. With the vibrato option this pedal is very versatile. As someone mentioned the depth could be bigger for rather extreme sounds, but you can get pretty authentic trem/vib sounds with it, at least enough to play covers of some 60s songs etc. It's built like a tank.

Small stompbox with two effects - vibrato and tremolo. You may want to get more depth from this thing, but you won't. Still, it can give you smooth vibrato sound to your guitar and interesting tremolo sounds. You can tweak it's waves to choose type of sound that you need. I won't say that it's agressive, but good enough. Also you can get stereo sounds from it, which is great. As I said it lacks some depth if you want real extreme settings. Also there's a volume boost in tremolo mode which can dissapoint you. It's OK and cheap.

The mono in stereo out function of this pedal has made it a versatile device that I have only grown to appreciate over the years

Absolutely fine for what it is designed for. Wonderfully cheap as well. I tried the Boss Tremolo alternative and this was just as effective.

nice pedal, I think it's better the tremolo than the vibrato

Vibratrem + Tremolo
