I bought it to “upgrade” my CryBaby. This pedal offers basically two different sounds (yellow and red coil). I ended up using the yellow one which is very similar to the CryBaby, which is a fantastic sound, but I always felt that the CryBaby had a somewhat “uneven” sweep. This pedal does not have this problem. I really like that the Q is adjustable and I used thus feature to adjust the sound to my liking. I also like that there’s an on/off LED indicator. Personally I don’t use the red coil. It sounds good, though. Fatter, but not as agressive. I don’t use the boost either, but for some, it may be useful. The build quality is really good and the visual design is very cool. Great pedal!
