The make up of the DOD FX63 Deep Freeze is really basic as it simply has four different knobs that each control a separate parameter. It has parameters for level, speed, depth, and hi EQ, which respectively are also labeled chill, cold, deep, and defrost. Good thing it has the real labels at unless I'm pretty sure I wouldn't know exactly what they were talking about! All in all, a very easy pedal to manipulate. I don't have the manual for the DOD FX63 Deep Freeze so I don't know how complete it is, but it really isn't necessary as the pedal is simple enough to use.
The sound quality of the DOD FX63 Deep Freeze pedal is about average, but is certainly useful and usable. I've only used this pedal for bass guitar, which is what it is designed for but I believe that it would also work with electric guitar or any other electric instrument. This being said, since it is specially designed for bass guitar I really wouldn't recommend using it with anything else. This pedal sounds good, but probably isn't suited best for the recording studio and is better for live shows because of its make up and average sound.
I've had the DOD FX63 Deep Freeze for about four years and it is certainly a good chorus pedal for bass guitar. It is really simple to use and while it has an average sound quality, it is definitely usable and is more than an adequate pedal. The price is the best part of the pedal as it is extremely cheap, making it a perfect pedal for the beginner, but has a suitable sound for levels above this. If you are a bass player looking for a cheap chorus designed specifically bass guitar, the DOD FX63 Deep Freeze is absolutely worth a look.
