Boss HR-2 Harmonist

[Brett Sinclair]

I have a Boss HR-2 that i would like to modify... it has 2 voices & 2 outs. If B is not connected, A outputs dry + amount of voice A + amount of voice B. If both are connected A outputs dry mixed with A and B outputs dry mixed with B.

I would like to change it so that the output B only outputs voice B NOT mixed with the dry input... (leaving me the option to have only the pitch shifted signal B)

I'm guessing that if i'm lucky this is as easy as desoldering one resistor... 

Does anyone have a schematic that could help me?

Sorry man ...this one hard find ... and not much used pedal. i have been looking for the PS3 ...
I tried the Harmonist and got completely wasted  how the heck do u play wif it ??
One suggestion would be to have a look at other BOss Schemo eg DD2 or  DD3 and figure out how they do it there  .

Hope this helps.

Yeah, i figured by now that the schematic is pretty impossible to find after numerous google sessions.  And i tried to trace between output jack and level pot, but the board is all smd double sided and it is driving me nuts...

I'm not using the HR2 to "play" really...   Most of the time i only use the whole octave up or down and now i'm trying to figure out how i can set it up in a feedback loop with a delay & mixer so it can be used to pitch up repeats (like the PS3 does) for "shimmer" (that's why i'd like it to output the pitched voice only).
Yesterday i used it with a Gameboy running nanoloop to create some crazy sounds... cool 

I'll have a look at the schemes for a similar boss pedal, cheers!

i have been looking for the PS3 ...

The schematic for the PS3 is the same as the RV3 it seems...
