Hello, I am very new to this.  I'm trying to build the Axis Fuzz (http://fuzzcentral.ssguitar.com/schematics/axisfuzzschem.gif) and have run into some problems.  First, I don't know what type or brand of pots to get.  Second, I can't tell from the schematic where the stomp switch is connected.  Also, can it be wired true bypass?  Third, I'm not sure how the stereo input jack works.  Any help would be greatly appreciated.

Thanks

It doesn't doesn't matter what brand of pots you use, most people use 16mm or 24mm Alpha pots, which most suppliers sell. The drive pot is a 2k linear pot and the volume is a 50k log/audio pot, depending on where you're from it might be easier to get hold of a 2k2 linear and a 47k log pot which will work fine.

There's examples of ways to wire up pedals true bypass here http://www.generalguitargadgets.com/index.php?option=com_content&task=view&id=33&Itemid=27. The easiest if you want a status LED is one of the 3PDT methods.

The stereo input jack disconnects the battery when the input jack is unplugged, this stops the battery draining when you're not using it. The tip of the jack goes to the circuit's input, and the sleeve is connected to ground. The black (negative) wire from the battery goes to the ring connection. That way when the input jack is plugged in the ring gets connected to the sleeve, connecting the battery to ground so it can power the circuit.

There's good info on jacks in the FAQ http://www.diystompboxes.com/wiki/index.php?title=DIY_FAQ#JACKS loads of other good stuff as well.

The pots are Omeg. Heres a picture of a 47k pot just like Roger Mayer's were, except the solder lugs and shaft lengths are different.
