Audio AmplifierCircuit - 30 Watts

Posted on Feb 7, 2014

I`m a bit of a newbie, but I love to experiment. I thought I would try to make a small guitar amplifier using some of the circuit designs posted here. I`m thinking of using this 30 Watt design (actually, the single 12VDC version mentioned in the comments below), but feed it with a preamp ( ) to be able to adjust input gain and have some tone cont

rol. Then I would like to add a master  volume on the backend, but I haven`t found any circuit designs for this. Only digital volume circuits, but I`d like to use a pot. Question #2: How can I add a master volume to this amplifer circuit In the comments below, you mention adding a volume pot to the INPUT of this circuit. That`s sort of what I`d be doing with the pre-amp. Would it be logical to place a volume pot somewhere in the OUTPUT
