Blend 2 Circuits

[irmcdermott]

Anyone know the best way to blend two circuits? Someone I know is looking for something similar to a JHS Banana Boost, which is pretty much a Rangemaster/Treble boost and a MOSFET Boost with a volume knob and a knob that blends the two circuits. So when its all the way to one side, you get all Rangemaster, all the way to the other side is all MOSFET, and in the middle is a blend of the two.

I'm thinking of just doing the two separate circuits in one box, but just need help figuring out how to wire that blend pot up within a circuit.

What you want is a panner, not a blender.

I have a project that is/has been in process to be verified a long time.

once again, Jacob pulls through. thanks man. look forward to your project.

If you need someone to verify it, let me know. SOunds like I have a perfect project to test it with

Jacob, I'd also be happy to help verify yours ...

I have built the ROG splitter-blend a couple of time.

For a passive blend circuit, you could do something like this, but it will drop your output by 6db:

You can always add an active make-up stage to get your level back:

I've emailed you a copy of the document Ian. Let me know what you think. It's a little bit more complicated, but Scott's active version is pretty close.

+1 on Jacobs blend. It works very well.. Almost to well, it took me a sec to figure out how to wire it in but if you build from scratch should be simple.
