Boost with blend knob.....

[Keysershades]

Hello good people...
Is it possible to make a blend knob between the dry signal and the weet from a boost ?
Something like this ?


I would like to build it into my guitar, so when the knob is turned down it's the dry signal and when up it's boosted.

Aparently i can't post the picture..
But it just shows the dry signal to log 2 on the pot, then the signal from log 1 to the boost and from the boost to the output and log 3 directly to output.

You should be able to do it with a double pot pretty easily. Just two output volumes wired reversed from eachother.

You'll probly need to balance it a little with a resister to ground on the boosted side though.

Find the Clapton boost for an example of how to do that, or the Sparkle Drive.

Great idea with the double pot! I have the pot from my old TBX cut tone control laying around, good enough?
I think it's a 1M and 250 ohm's, not sure though!

But can you tell me whu i can't do it with a normal pot ? Like the old Telecasters

[Bad Chizzle]

Not sure, but if I was going to start, I'd maybe look up an old Tele schematic and go from there. Basically though, I'm thinking you would just need to build a very small passive mixer and put it all up in there after your two parallel outputs. That's why I suggested the dual pot. I believe with the dual pot set up so when one section goes up the other goes down, you will have built a one knob mixer. You could even have an overall level control after that if you wanted. I'm just spitballing here.

I get it, and what would be cool! But i rather use one pot since a double pot is kind a hard to get (for a fair price) were i'm from!

You linked to your PhotoBucket _album_, not your PB _image_. So the IMG code can't work.

There's ways to link to a PB image. If you click-click-click the right stuff (??), they actually tell you the code:

Code Select Expand

But your image is 960 pixels wide. So wide that if you did get it into the forum message it would slop off the side of my screen. And while I often draw that big, I can see smaller; it is polite to re-size images for in-forum posts. (For more-detailed images, with a link to the full image or album.)

And PhotoBucket sucks. Use tinypic.com

That drawing can't be right. Both collectors tied together? Nothing to base of Q2? OK, I see where this should be going.

> blend knob between the dry signal and the weet from a boost ?

If this is a "clean" boost, then "blend" is the same as "less boost".

Even if the "boost" really goes into the "dirty zone", adding-back the direct sound mostly dilutes the effect.

But yeah. Connect a 100K pot from input to boost output. Take your final output from the wiper. This way may squeal when nothing is plugged into the input; can't tell without some numbers on the drawing.

Exactly what I was thinking as I read this.. why blend a boost ?
