Pedal Parts

For reliability I recommend using only high quality US made mechanical parts such as connectors. The following is my recommendation.

Jacks and plugs - I highly recommend Switchcraft or Neutrik connectors. They are the highest quality and are available from Tubesandmore and Markertek.

Coaxial power jack - chassis mount - Jameco 151590

Passive bypass switch - Lots of good low cost parts if you are going to build your own Tube Screamer.

JRC4558 - ebay
