Mooer MRT1 Soul Shiver

Product Information

A rather affordable, great-looking, streamlined uni-vibe clone from South America that, with four controls (Level, Depth, Rate and Voice), can deliver a wide range of juicy vibe tones. Again we have a lot of the usual suspects here and not atypical numbers for Brands or Countries either. Obviously there are not that many salient candidates in the Dimension category - which means we're a couple here off having a full house. There will likely be some healthy debate about some of my choices and omissions - while I feel that most of the obvious ones are present and correct. The pedal comes with three control knobs, including Depth, Rate, and Lag control knobs. Plus, there are the selectable waveform and tap tempo division switches. Also, there is the D-C-V knob which allows you to blend the dry and wet sound to give you a Dry, Chorus, or Vibrato tone.

Flanger is probably my favourite current modulation - actually I really love my core analog quartet of Harmonic Tremolo, Chorus, Flanger and Phaser - where it's the sort of BB-size ThorpyFX Camoflange which is very much my current Flanger of choice. I have 3 in this highlighted listing - Boss BF-2, Chase Bliss Audio Spectre, and the A/DA PBF Flanger. I fully intend to get the excellent and recently revamped Retro-Sonic Flanger and Subdecay Starlight at some stage too. For me this often goes hand-in-hand with Filter type pedals - and there is some degree of overlap, while there are also distinct pedals in each category. Sometimes the separation is rather arbitrary, while I stand by my selections here. The one Auto-Wah pedal I own in this category is the Custom Shop CryBaby Q-Zone Fixed Wah - and I've still to get ANO from the Boss AW-3 Dynamic Wah, Mad Professor Snow White AutoWah - or possibly even the brand new Tone City Funny Boy Auto Wah.

What do people like about Soul Shiver?

For Auto-Swell I have a number of workstation pedal algorithms / voicings that do that sort of thing - I'm not actively seeking a stand-alone solution - I would of course grab a Waza Craft Slow Gear if that every materialised - otherwise I'm really waiting for some slightly more clever / innovative dual-footswitch execution! Leslie set out to create a “moving” speaker that would rotate on its axis and throw the sound as it spun. His original design used a spinning treble horn, but he later improved on it by employing a crossover circuit to split the high frequencies, which went to the horn, from the low frequencies, which were fed to a large speaker that faced downward into a rotating drum-shaped baffle. Though his early cabinet had one speed—Tremolo (fast)—he later created a slower speed, called Chorale, so that the sound was always in motion. Neo Instruments was among the pioneers in this field, blowing everyone away with the Ventilator, a desktop-style pedal that emulates the Leslie 122, one of the most famous cabinets in the company’s historic lineup. While the Ventilator’s feature set is no richer than what’s offered on some pedals in the Leslie Emulator category, the quality of its emulation is truly exceptional, with a depth of realism that few can match. For guitarists, Neo created the Ventilator II, which offers the same features in a smaller format, along with expression pedal control. Pros: It sounds just like the original unit, solidly built, with a slightly smaller footprint; true bypass option. | Cons: Rather pricey; the expression pedal has a proprietary input that only works with the company’s accessory. Chase Bliss Audio Warped Vinyl is a highly tweakable and versatile all-analog chorus and vibrato pedal that offers clean and polished effects. The pedal replicates the sound of warped vinyl records, which gives amazing vintage chorus and vibrato effects. There is plenty of control under your hand to shape your sound, including dual waveform switches, tone, lag, mix, RPM, depth, and warp knobs.

My first proper modulation box was the Strymon Mobius, to which I first added my sole stand-alone modulation effect then - analog harmonic tremolo - courtesy of the Chase Bliss Audio Gravitas. I so much liked the Gravitas that I acquired all 4 Chase Bliss Audio Analog Modulation pedals - with the addition of Spectre Flanger, Warped Vinyl Chorus/Vibrato and Wombtone Phaser. For the Mini Filter - it's between the F-Pedals Punkmonk, Function F(x) Accufunkture Mini, Menatone Mail Bomb Mini, and Mooer 'Envelope' Filter Mini. My choice here is the Jr Accifunkture in that appealing red metallic enclosure - with proper milled alumimium knobs. For the Minis it's a 3-way between Malekko Omicron Phase Shifter, Mooer Ninety Orange, and the MXR Phase 95. The last mentioned being the obvious shoe-in. In fact with MXR being the heritage Phaser brand - the Phase 95, and Phase 99 are my favourite varieties over the classic 90 and 45.A popular, 18-volt, re-engineered, smaller version of the original, now out of production Deja-Vibe, which started the Uni-Vibe clone trend. Mini-toggle switches between the original Uni-Vibe warmth and the “Modern” option (louder, brighter). Also available in Stereo. An authentic Leslie simulator will be stereo and possess a depth of realism you’re unlikely to find in a cheaper, mono pedal. Pros: Rather affordable; great sounding; the Voice and Throb controls provide flexibility without complications. Cons: No tap tempo or Expression In functionality. The more recent Electro-Harmonix Lester G (also stereo) features a specially designed compression circuit to supercharge the rotating speaker effect on guitar. Controls include fully adjustable tube-style overdrive, Fast and Slow modes and an Acceleration control to dial in the rate at which the effect transitions between speeds. A “Type” switch delivers the usual “Vibrato” and “Chorus” voices, while the “Tone” switch offers three different EQ settings Original, Bright, and Custom, with the latter’s setting being tweaked via a trim pot on the side of the case.
