Hi.
I wanna build a simple line level summing device for use in my guitar rack. Now, I've read that you can just put resistors on the hot leg of each input, but also that this causes attenuation and might cause channel bleed. From what I understood you could use op amps instead. How would these be connected in a simple 2-1 mixer? Also, is this possible to do with 9VAC?

Check out "Figure 2" at the link below for a simple op-amp based mixer.
