Add octave effect to Silicon Tonebender MKII

[rbruss82]

Hi guys.  Today I tried adding an octave effect to my Silicon Tonebender MKII circuit.  I basically added a 42TM022 transformer and two 1N34A germanium diodes at the output just like in the Tycobrahe Octavia.  While it did seem to improve the sound of the fuzz, it did not produce an octave effect.  I am wondering if it is because the Tycobrahe Octavia uses a combination of NPN and PNP silicon transistors, while my MKII circuit is all NPN silicon transistors.  Does anyone have any ideas of a way I could add the octave effect to my MKII? By the way, the schematic I based my MKII circuit on is from generalguitargadgets.com and it is here:  http://www.generalguitargadgets.com/diagrams/tonebender_m2p_sc_ns.gif

These circuits are great, but very distorted. Contrary to popular belief, octavia type circuits hate high gain and distortion. It covers the octave sound with a lot of different frequencies being accentuated. Back off on the gain & distortion and you should be fine.pl

  Since you're this far...

  Post about Tycho producing better octave [cleaner or something] at higher voltages may be of use, providing the capacitors are rated for whatever voltage you go up to.
  I haven't noticed much improvement on guitar signals above 12v for stompboxes, [Have noticed when going from 9v to 12v tho] that may or may not apply dirctly to octave in tycho, going to 12v is probably enough to hear a difference, if there Is a difference, I haven't tried a "HV" Tycho.

Hee heee, I love seeing that schematic!!
