I was looking for a budget price chorus/flanger/phaser pedal and the Mooer Mod factory is a bargain! The chorus, flanger, phaser are excellent in sound quality and I really like the tremolo too. Personally I wouldn't particularly rate the low bit and ring modulator effects but the auto wah, stutt, rotary, liquid are quite usable. The pedal does take a bit of tweaking to find the desired settings and the printed effect names beside the dial knob are way too small, so I had to add stickers with bigger letters like CH, FL, TR etc so I could see the selected effect names. I also like the tap tempo option too. If you are looking for a cost effective multi modulation pedal but in a tiny box, look no further than the Mooer Mod Factory.
