Help With A Schematic


I've just completed this device and it does what it's supposed
to(distort a guitars output signal) but has no gain... Can anyone help
me try and get more gain out of this pig? Perhaps change some of the
devices values...add pots? Who knows I don't... see this hyperlink to

Thanks
Bill

What transistors are you using?

Start by lowering the 4.7k a bit

Lower it to what value ?

I have no experience with guitar effects, so I need to ask what is the impedance of the source driving this circuit?
You might try increasing the 22k to 47k or 68k to see if that makes a difference. You should also check very carefully that you built it right.

The first thing I would do is to verify your construction by taking some DC bias measurements with the input shorted to ground. I'd expect a voltage of 2.1V at the collector of the first transistor, for example.
