triple pitch guitar pedal

Hello again,

I was curious as to if it'd be possible to have an analog triple pitch guitar pedal? I currently use a Boss octave diveder for a lower pitch which also plays the normal guitar pitch. I'd like to get a pedal that does the lower pitch, the normal pitch, but also a higher pitch as well *up to one octave higher*. The Boss Oc-2 I have offers down to 2 octaves lower, but I never even consider anything that low....

I'd like for this pedal to be capable of producing 1 octave lower, normal signal, and 1 octave higher at once....with as clean of a sound as possible. The Oc-2 does add a little distortion, but nothing terrible.

(I don't know if this is technically correct, but) it would seem easier to use a digital device to add the upper octave. How about one of those Boss pitch shifter jobs? A used one maybe? Probably better sounding ones, maybe Eventide. I've got an older half-rack Boss pitch shifter/delay, but the sound quality of the pitch shifting is not that great, which seems to be partly from the use of crappy op-amps. The basic audio quality doesn't seem good. Probably (judging from having screwed one up), someone that knows what they are doing could improve the sonics of these cheaper types a lot. Also, the A/D, D/A processing and software must be responsible for some of the sound, but I don't know how much percentage-wise.

Stephen Giles	If you want up to an octave up, try the EH Guitar Synth - see my drawing on Hammer.ampage.org Stephen

The Boss Harmonist will do exactly what you want. It will do 2 harmonies, and each can be set, so you could get octave above, octave below, or any fraction thereof. It will do intelligent harmonies...just set the key you want. There are stereo outs so each harmony could be sent to a different amp, and if you use distortion before it, there is a trigger input, intended so you run a clean guitar signal there to improve tracking, and the distorted input into the main input. The result is the ouput will be distorted, but tracking will be better. This unit tracks better than analog units. It was pricey, over $150 new discounted, but I think it is a great pedal.

Mike Cornett	Pricey at 150 bucks?? sheesh, that's nothing...I see that it can do 2 pitches simultaneously, but does it allow the original pitch as well??? (so 3 pitches)

Steve Dallman	The Boss Harmonist has the straight signal mixed with the harmonies. You can control the level of each harmony, but the straight level is static.

Mark Hammer	There is also a construction article for a digital/cmos Harmony Generator that provides a wider range of intervals to choose from, as well as up and down from pitch. This could be readily modified to produce both higher and lower notes simultaneously. I have a schem somewhere for an older Pearl unit that would provide octave doubling and division in a small package. I'll try and post it soon.
