Tycho* Octave

This is the octave up sound similar to the Jimi Hendrix sound of the Purple Haze solo.  This is the most intense of the Octave-Ups that we know of.  We’ve added a PreGain control, so that it’s possible to tone down the insanity and hear some nice Octave sounds.

• Project History file

Buy a TOCT 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.

 JD’s Comments:

This project was altered to be an NPN circuit which means that you can use this box on the same power supply as most other pedals. I’ve built both the PNP and NPN and the sound is the same. R1, R14 and C7 are optional. If C7 is not used you need to use a jumper in its place. The standard octave sounds seems to come out better if you turn the intensity down some. With the controls on full blast you get some great swells and wild sustain.
