Project · Fuzz Tones
Jordan™ Bosstone™
This is a replica of the Jordan™ Bosstone™. It's a great little fuzztone that can be built with silicon transistors and still has an awesome fuzz sound. We are able to get wailing sustain and feedback even at fairly low volume when we play this one.

Everything you need to build it
Jordan™ Bosstone™ Ready-For-Transfer Printed Circuit Board Layout - For use only if you are a complete DIY person who wants to etch and drill your own PCB. Otherwise, we recommend you ignore this PCB mask and buy the Ready-to-Solder Printed Circuit Board or Complete Kit.

This is a JordanTM BosstoneTM Fuzztone replica known here as the JBT Fuzztone. This is a very simple kit to build. Follow the Bill of Materials, the Layout diagram and General Build Instructions. Note that the kit may come with a “can” transistor for Q1, below are the pin designations.
Here's an inside view of the unit we built to give you some general ideas if needed.
Here is a chart of voltages taken at the transistor pins. Use these voltages as a guideline. You may not get the exact readings listed, but should be somewhere in the area.

Ready to build? We have the kit.
Buy a Jordan™ Bosstone™ Complete Kit. Includes all the parts and materials you need to build one, all for about the price you would pay for a PCB and parts.
Would you like a Ready to Solder Circuit Board for this project Note: If you buy the kit, the Ready-to-Solder Printed Circuit Board (RTS PCB) is included in the kit. You do not need to purchase this Ready to Solder Circuit Printed Board if you buy the kit.
