PLI-01 : Not good for studio use.

Sturdy good build quality and nice design, but sadly not really useful for studio recording use. I was hoping it might clean up my guitar signals a bit, and to be fair it does isolate the player from the guitar (ie. there is no longer any extra buzz when the player lets go of the strings), but unfortunately this comes at the cost of adding a lot of noise to the signal and also reduces the overall gain level and shaves of some high end. Not good for noise or tone basically. Unless you specifically want to do some guitar feedback thing where the player isn't touching the strings, I'd give this thing a miss. Lots of people are saying it's good for live sound though, which I know very little about so it might be useful in other areas.
