Andy is correct that these affect tone of the Stickup. They suck the highs right out. I have finally found a simple circuit for an active stereo (or more) to mono device and I'm planing on making one to try it out this summer. I'll post the results.

Could that little circuit we use just be combined on the input of a mono circuit or the output of the stereo one thus combining it to a mono output with any degradation of sound quality or is there more to it than that? (If so, I will need to correct something I said in another post.)

I would not have expect the device pictured & mentioned above to effect the sound. I am learning but my info stores must be missing vital information because to me that doesn't make sense.

Thanks again,

I don't think this would work. To combine 2 or more signals without degradation you really need a mixer circuit.
