I just want to say that I really love the sound of the rs120 multimode.
Very warm.

But far as the RES loop, about the only thing I've done is put the
notch out into it and it gives a brighter results. Bob told me they
added the res in/out by just tweeking the circuit and found these two
modes that seemed interesting and added it to the faceplate.

Can anyone give me some great examples of the use of the res loop I
am really curious.

thanks in advance,

P
