Electronics Forum / CAD / November 2005Help 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 view the schematic ( http://www.diystompboxes.com/pedals/orange.jpg ) Thanks Bill > I've just completed this device and it does what it's supposed > to(distort a guitars output signal) but has no gain...

The other problem with this circuit is is has an input impedance too low for most guitars. Try changing the 22K feedback resistor to 220K. Ian which is the second transistor? > which is the second transistor? The one on the right of the circuit diagram ;-) Oan what happens to the 4.7 and 470 resistors and the .1uf cap... and the 9V+ input point?
