wet / dry control knob

[Nikos]

hi there, I wanna add a blend knob to control the dry vs wet signal amount. I tried with one pot, connect the output to the middle pin and the signals to left & right pin, didn't work. I tried also with one stereo pot like that

and also didn't work. the circuit i'm working on is this:

!!!!I want to place the mix pot after the volume pot to balance the wet signal with the dry one because the output from the transistor is much higher than the dry.

Are you planning on using this pedal in a stereo set up? If not, I'm not quite sure why you need the blend pot. The output volume pot should suffice to balance between the effect and bypassed volume.

[Nikos]

It's for mono use. Beside the volume I want to contol also the mix between dry & wet, to shape my sound. It gives you more options

I think digi2t may have missunderstood a bit when you said 'dry vs wet'. That does sound like you want to make up the difference between the effected and dry. But you want to add a blend so you can bring in some clean signal to the effected signal.

Do a google search for the buff n blend. It should be on the Beavis Audio site. That will get you what you need.

i think this is what i want. But I was expecting something less complicated.. Has anyone try this?

Ahhhh, OK, got it. Thanks for the clarification Matt.

Niko, as Matt suggested, this should do just fine;



"Effect send" will go to the BazzFuss, and the volume out of the BazzFuss will go to "Effect receive". As the schematic recommends, R4 is optional, if the BazzFuss is still too loud in the blend.

You may want to consider building everything on the same board.
