What is the difference between a Univibe and Tremelo?

[gearo999]

Are they the same?

[ChorusCrackpot]

No, they are not.

What is the difference? I'm new to these kind of pedals.

go to youtube to hear the sound diferences.. Its hard to describe. univibe is more uh...chorusy/phasery sounding. tremolo is like volume up and down repeatedly. completely different effects

Tremolo is just a change in volume. Univibe was supposed to emulate a rotating speaker, but ended up being its own thing. It combines a change in pitch, phase and volume to emulate the doppler effect you get from a rotating speaker.

They aren't "pedals", they are effects. Pedals are just a type of device housing that can produce those effects.

You have a TC Electronic G-Major2 listed in your signature. Turn it on and you'll find those effects in there. Try them out and you will hear for yourself the differences.




Tremolo is a modulating volume effect- the volume level decreases and increases, in a pulsing pattern.





Univibe was created to emulate a rotating speaker effect, but tends to produce a slightly different sound.

Way to be persnickety. It was clear by all what the OP was asking. And “pedals” is obviously shorthand for effects.

To the OP:

A tremolo effect is a device that does amplitude modulation. There are a few ways to do this that each give the tremolo a certain feel but most use a Triangle wave LFO to modulate the amplitude of the signal (Fender amp tremolo's use a triangle wave for modulation and that is the baseline for many pedals to start from). In short it does nothing more than bring the amplitude of the signal up and down at a set rate (the Speed Control which controls the speed of the LFO).

More advanced tremolo’s have multiple wave LFO’s but most people do not need more than just the good old fashioned triangle wave tremolos…

As someone above mentioned, a Univibe is a mix between a phaser, pitch shift and a tremolo. It was meant to emulate a Leslie cab (which it did a bad job of but became its own wonderful effect), using the principals of the Doppler effect. The tremolo aspect gives what is commonly referred to as the "Throb" of the Univibe. This is pronounced due to the second part of a Univibe, the 4 filters. This causes a phase type sound. The effect, though often associated with chorus, is in fact created through a staggered series of phasing filters, unlike the usually aligned filters of a normal phasing effect. So although it is named "Chorus" on the effect itself, it is actually tr4chinally a phaser. The term "Chorus" just stuck through the years, though it is not a chorus (chorus is caused through either delay or pitch modulation).

Hope that helps...

I beg your pardon?

If you read the thread creator's signature, s/he has a TC Electronic G-Major 2, which is a rackmount effects unit. So one would suppose that saying "pedals" would not really refer to "effects", unless they don't know what they actually own, especially since effects like tremolo and Univibe would most likely be in the G-Major 2.

Vibrato deals with change in pitch. Tremolo deals with change in volume.
