What's the diference between a vibe pedal and a leslie simulator?

[pedrozepelim]

Can you explain this to me?

[slopeshoulder]

well, i can't answer technically, but a vibe was itself originally a leslie simulator, but the similarity is only slight. Recently, better simulators of leslies (rotary) have come out, but the vibe took on a life of its own over the decades and is beloved by guitar players. the leslie sounds more rotary-whirr, the vibe sounds more watery. They're different. Find some clips and give a listen.

In my experience, the vibe is a watery pulse-like effect whereas the leslie is chimy in how it pulses similar to a chorus.

Yes the vib is a pulse like sort of effect, very much like a phaser and therefore they can double on songs requiring this kind of modulation.

Leslies have a more symetrical sort of sound, more of a warble than a pulse and of course have 2 speeds that they ramp between.

i believe the univibe was originally created to emulate a rotating speaker.
it failed by a long shot in my opinion.
but.
it has a sound all its own........kind of similiar to a 4 stage phaser.
only more thick and sloshy and watery.
listen to "Machine Gun" by Hendrix.
thats a univibe orgasm.
as for leslie sims............the only one that gets close to a true leslie sound is the Boss RT20.....and the HK Rotosphere.
For a good leslie example..........listen to "Angel"........also by Hendrix.
anyway, a univibe is its own effect.
its nothing like a leslie.
a leslie sim........well most dont sound like a leslie either in my opinion.
A good chorus can sound more like a leslie than a univibe.
still confused?

I have a Retro Sonic Chorus/Vibe, it's a great unit but, it's nowhere near replicating the rotating speaker sound of a Leslie or a Fender Vibratone(aka SRV). This is primarily because these sounds fall somewhere between a tremolo and a vibrato. In the case of Stevie's Vibratone, there really is no pitch modulation, as in a vibrato pedal but there is volume modulation combined with the in and out of phase sound caused by the speaker or the drum(in the case of the Vibratone) rotating. Add to the fact, most guitarist who have used Leslie type speakers, used the wet sound with the dry to create a specific texture rather than a pure sound. The closest I've ever come to replicating the Vibratone sound was with an old brown Boss CE-2B bass chorus, it seems to have the pulse and the phasiness, without a huge pitch modulation, and it's not as trebly as most guitar choruses, plus it's got a mix control so you can set the ratio of wet to dry, it just sucks that it's not true-bypass and messes up my sound when it's off, but until I can find/afford a Vibratone...this is probably the best solution, with a true bypass loop pedal. If anyone out there wants to make a reasonably affordable Vibratone clone....I'm interested!!!!!!
