Hi
Here I have a simple question regarding stepped attn.:
I am thinking about building a balance-pot as a stepped attenuator, probably ladder style.
Center-Position would be both channels fully open, a turn to the left attenuates the right channel, a turn to the right attenuates the left channel. The other channel is left untouched.
I could then just install a bridge along the remaining positions (right half of the left channel and left half of the right channel), right? (thus requiring half as much resistors)
thanks!

Yes, that's how balance controls are usually built, which reduces the signal loss to 0dB. See fig.B here.
