A friend told me that I should get a univibe.But if I'm not mistaken doesn't a univibe do what a vibrato and chorus pedal does and vice versa or am I missing something?
No. Vibe is really unique. Most of the time they have a switch that says 'chorus' and 'vibrato', but it's not like normal chorus or vibrato. The chorus is actually the vibe sound like Hendrix and Trower use(d), and the vibrato is more throbby than 'normal' vibrato.
