Mooer MRT1 Soul Shiver

I had been looking for a univibe pedal and saw this reviewed. It can be switched between chorus, vibrato or rotary and each one is fun. The chorus is very good and I have mainly been using the vibrato. The rotary is just fun, though. It is well made and arrived early in a very good package.

Arrived earlier then anticipated, husband delighted!

Great effect.

Really like this little bugger. Doesn’t take up much space on the pedalboard and has a different sound than switching on a straight chorus or phaser or flanger.

I purchased this pedal for 3 reasons. 1. I had very little space left on my pedal board. 2. I was looking for a basic vibrato/chorus effect for the stage. 3. I wanted a Leslie style effect for the stage. This pedal claims to do all 3 in on pedal, which it does to an extent.It doesn't take a battery, you must have a 9v pedal supply (The common Boss standard) 9v Barrel Connector with Center-pin Negative.Let's break it down:The chorus is a decent chorus and the controls on the unit allow a good range of sounds that is very useful.The Vibrato works, but is a little to chorus-like for my tastes. I expect pitch shift with vibrato but not so dramatic. For lack of better terms this vibrato was more swirly like a chorus than warbley like a vibrato. I can dial out most of the swirl with the controls but the vibrato becomes more subtle.The Rotary setting (Leslie) is convincing for a pedal... Except it doesn't have the ramp-up and ramp-down (Speed-up, slow down when activated and turned off) simulation that higher-end Leslie sims have. This isn't important to me, but it is to some people so I think they should know this.It can get a reasonable SRV 'Cold Shot' sound. I use a real Leslie in my studio and compared them. This is good enough to fool your audience in a live setting other than having that ramp-up/down period.I'd have given it 5 stars for the price, size and build quality for the cost, but the vibrato was a little to chorus-like and the Leslie sim didn't have the ramping feature. Still, It's not expensive, gives many sounds and fits in the last tiny corner of your pedal board.

This isn't the most accurate univibe clone but it is really good sounding. It definitely has the phasey bridge of sighs thing going. At this price it's a no brainer.

Pedal worked for a day, sounded great and then would not power back on. I returned it, got a replacement that only produces a loud hard tone regardless of what I have put in the input signal. I really wanted this to work but returning it for a refund, and will continue my search for a more reliable working pedal.

Not a good sounding pedal to my ears.
