Note that I bought two of these effect pedals, to slightly detune for a nice stereo effect! I did not however, add any external effects or processing. For simplicity\u2019s sake and to prevent the review video from being too long, I kept the various test sounds on the Korg EX-800 synthesizer to a minimum.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"M-Vave Mini Universe and Korg EX 800: Effects and Keyboards\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/R0JQLk4_uME?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Effect type details<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On the types below where Param1 and Param2 controls tone frequency, I was happy to discover that the adjustment did not affect the dry signal.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Room<\/strong> \u2013 Simulates a relatively small, simple-structured room, where many reflections are absorbed by soft material, and the sound reflected by the walls<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Low pass tone control<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Drift; Pitch of the wet signal, is slightly modulated to produce a \u201cvintage and charming background sound\u201d<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Hall<\/strong> \u2013 Gives a wide, slightly scattering feeling, simulating a grand ambient sound.<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Low pass tone control<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Drift; Pitch of the wet signal, is slightly modulated to produce a \u201cvintage and charming background sound\u201d<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Plate<\/strong> \u2013 Simulates a reverb created in a large metal container, with a very bright and powerful sound.<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Low pass tone control<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Drift; Pitch of the wet signal, is slightly modulated to produce a \u201cvintage and charming background sound\u201d<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Spring<\/strong> \u2013 Simulates a reverb going through a spring enclosure, which picks up resonance. &nbsp;<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Low pass tone control<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Dwell; Controls number of springs.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Shimmer \u2013 <\/strong>An adjustable pitch shifted copy is added to the wet sound, creating dissonant, \u201cscary\u201d, or harmonic and ambience sounds.<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Pitch; Adjusts the pitch shift, where minimum is same as input, and maximum is two octaves above.<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Amount; Essentially the level of the pitch shifted sound.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Cloud<\/strong> \u2013 A large ambient reverb.<ol><li>Param1 \u2013 High pass tone control<\/li><\/ol><ol><li>Param2 \u2013 Low pass tone control<\/li><\/ol>\n<ol class=\"wp-block-list\">\n<li>Param3 \u2013 Diffusion; Softens the early reflections creating a more diffused reverb.

The knobs are ok, although slightly wobbly, and could use perhaps a bit more distance between them, for easier adjustment. The Type (variation) switch however is difficult to switch to a position where it locks, in other words the lock positions are too loose! The foot switch seems very solid and of good quality. The pedal has four small rubber grip feet in each bottom corner, preventing it from sliding much, if any.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Accessories<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>None<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Documentation<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One tiny booklet, in seven languages, with seven pages per language.<\/li>\n\n\n\n<li>Provides decent enough information, although the tiny text size is hard to read.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Size<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dimensions: 60mm wide x 112mm deep x 24mm tall or 40mm tall with the knobs and foot switch.<\/li>\n\n\n\n<li>Weight: 236 grams<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Pros:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Very affordable.<\/li>\n\n\n\n<li>Good quality and very useful reverb effects!<\/li>\n\n\n\n<li>Plenty of adjustment possibilities.<\/li>\n\n\n\n<li>True bypass switch.<\/li>\n\n\n\n<li>Solid metal case.<\/li>\n\n\n\n<li>Decent knobs.<\/li>\n\n\n\n<li>No audible noise that I was able to notice.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cons:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Type selector knob\u2019s lock positions very poor!<\/li>\n\n\n\n<li>Microscopic manual!<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">9 reverb types, or variations effects, that are all quite useful, and with a good set of adjustment possibilities. Note off course here usability varies dependent on what music type of instrument you are using it with. In particular you may find a few more useful effect types than me as a keyboardist, if you\u2019re going to use this on an electric guitar. Sound quality is noise-free. Build quality and knob size is decent, although knob spacing could be slightly better. Anyways for under $30 including shipping and tariff taxes, I found it a very deal, so good I bought two!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Availability<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/s.click.aliexpress.com\/e\/_c3KRrYrH\" target=\"_blank\" rel=\"noreferrer noopener\">AliExpress<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/amzn.to\/3NGMUJo\" target=\"_blank\" rel=\"noreferrer noopener\">Amazon<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/temu.to\/k\/pdudbakt3rq\" target=\"_blank\" rel=\"noreferrer noopener\">Temu<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Overview The M-Vave Mini Universe is an economical Chinese made, multi-variation reverb effect pedal, equally useful on guitars and keyboards, including synthesizers.
