Hi all,
Here is a discrete transistor circuit to do boost and cut of a (switchable) single band from an old circuit (Acoustic 360 preamp).

Can anyone help me understand which end of the pot is boost and which end is cut? I am not that good at discrete circuitry and I don't understand the concepts around feedback from the collector to the emitter.
Thanks all!
