These pedals suffer some serious treble loss when using the tuner out.
My mod installs a Klon Style split-buffer that sends even signals to both outputs solving the issue of the tone lose.
It will sound and look better than ever with the addition of some led’s inside.
You have your choice of colors on the LED's Choose from Red, UV, Yellow, Green, Blue, or PINK or mix and match for unusual color combos. The one on top has one red one UV and one blue. I also highly recommend doing one yellow, one green and one blue. I call that one the Aurora color scheme. It always is sure to please.
This does make your pedal a powered pedal so you will need to hook up 9v power to this. Standard Boss style 2.1mm negative ground power supply required.
