All user reviews of 3/5 for the Dunlop JD-4S Rotovibe

Leslie tremolo simulation
and chorus that does not look like a chorus

UTILIZATION

Surper simply connecting a jack on each side, everything is handled the foot pedal is used to control the rotation speed, the black knob depth (or intensity) and a small red button on the side that toggles the tremolo chorus mode mode

SOUND QUALITY

The tremolo was finally disappointed me, not very accurate and it's the kind of effect that will be used once every never, or so it may zicos other drunk very quickly.
I have a dod vibro thang that I find much better and more versatile in tremolo (dod phaser is the mat)
For the chorus against Whaou!
I use it with guitar and keyboard.
This is even more effective with the guitar

I put way to the note, but actually it is pretty poor for the tremolo and perfect for the chorus.

OVERALL OPINION

I had bought for the tremolo as a leslie simulation but I almost never lutilise.
For the chorus against me stuck with the downturn when it snaps into the position slowly!! A basic guitar and an amp with this rotten on the arpeggio air "shine on you crazy diamond" and it does.
It sounds very Led Zep, Ben Harper too.
The pedal in my opinion is indestructible, but also heavy and bulky, I rarely use the pedal shift: I'm mostly in chorus / slow position / maximum intensity.
If I found a small pedal-type boss with this setting and the sound plus the slowdown in the engagement I revendrais rotovibe, but .... a boss chorus does this sound absolutely beautiful.
A small snippet here in the version with the addition of a chorus and delay, drive a elka leslie:

This is basically a vibrato effect with expression pedal or a chorus effect with expression pedal. I am assuming it is analog, but I am not 100% sure. The only editing you get is modulation control with the foot pedal, intensity control with knob on the side, and a switch for chorus or vibrato. It cannot be hooked up to a computer. It is only 1/4" audio in and out and it is not rackable.

UTILIZATION

Its very easy to set up. Plug it in. Step down to activate, select chorus or vibrato (I alway forget which one is which, one turns the light yellow, the other turns it green) and adjust the intensity. Thats it. There is really no need for a manual. I never looked at one and was able to figure it out very shortly.

SOUND QUALITY

I honestly don't care for this pedal overall. The vibrato is pretty fun because of the expression pedal, but in order to turn it on, you need to push the pedal all the way down, and that means you always have to start at minimal vibrato and adjust it back up. It would have been nice if there was another way to activate it so you didn't have to reset it everytime you wanted to turn it on. The chorus is ok. I own a Diamond halo chorus and the Rotovibe can't even touch that baby. I used to use this in my synth/alt vocals Mixer's effect chain to create some crazy vibrato effects, but in the end, I took it out of my arsenal and am trying to sell it. The

OVERALL OPINION

I have had it for six months and I never really used it during that time. What I like about it was the idea of the built in expression pedal, but when I got it, I realized the activation flaw and was very sad ): Also, it doesn't even have stereo options, whats the deal with that. Even cheap boss chorus pedals have that. Again, if you want fantastic chorus, get the Diamond halo chorus, or even and Analog man chorus pedal. Either one will make the rotovibe look childish. Overall, I am disappointed in this pedal. I got mine used for $100 and I regret it very much.
