Flamma FS05 Multi-Type Modulation Effect and Yamaha PSR 36: Effects and Keyboard

Review Flamma FS05 Multi-Type Modulation Effect and Yamaha PSR 36

Sound Effects and Keyboards / Synthesizers:

In this video I will demonstrate and review the Flamma Modulation FS05. It is an economical Chinese made stereo multi-type modulation effect pedal, equally useful on guitars and keyboards, including synthesizers. Please note however, that I tested this guitar effect pedal on a keyboard. If you try this out with an electric guitar, your sound impressions and usability will most likely be different from mine.

Main Features
• 11 Modulation Effect Types (Chorus, Flanger, Tremolo, Phaser, Vibrato, Rotary, Liquid, Auto Wah, Stutter, Ring Modulation, and Low Bit)
• Rate, Depth, plus Ctrl 1 and Ctrl 2 adjustment knobs.
• Stereo input and output. Mono to stereo output.
• Preset Storage – Parameters can be stored and recalled using the footswitch in seven preset patches. A LED light depicts current preset in use.
• True bypass footswitch.

Testing
Note even though I own more than 40 synthesizers, I tested this with a simple Yamaha PSR-36 keyboard that does not have any internal effect processing. Furthermore, I did not add any external effects or processing. For simplicity and to prevent the review video from being to long, I only tested the following sounds; Bass, Electric Piano, Strings, and Bells.

Conclusion
For about $60 you get eleven different modulation effects that are mostly very useful. Featuring stereo in and outputs, and signals being processed for eight of the effects in true, slightly different stereo, even with only one mono signal connected, is great! Still, I would have liked if the remaining three effects, Tremolo, Stutter, and Lo-Fi, would also have been truly stereo processed. The fact that this unit auto-loads currently selected preset, whenever one switches bypass off, and you have to remember to save parameters as a preset first is very annoying! Anyways, build is solid, and the signal quality is generally noise-free if you keep you level low on your mixer/preamp.
