Digital volume control You can control volume with a DS 1802 ic. It's a digital volume control with 50k resistance.I think it can be controlled with 2 bottoms.Or it doesn't works you can built a simple circuit with an 74193 counter,an 4016 analog switch and some resistance. I have this circuit,if I find it i share here. •••
