Good sound quality can be obtained as long as it gets tweaked properly with a preamp or mixer.
I don't think you can use this on its own without a preamp.
1 thing this mic pickup lacks, is a kill switch.
It would be great to have that when you get off stage or tuning the guitar but instead there is a to turn the volume knob off.
To conclude,
It works well, Will get another one hands down. No complaints.
Thanks
PS: don't forget to add a kill switch if there is a version 2.0
