FOXX: Tone Machine, Vero & Point to Point Layouts

One of my favourites - the Foxx Tone Machine.  I've posted a couple of layouts, one stock, the other is the Aion FX Vulcan.  The Aion FX mods make the Foxx even better - I prefer it with the mid switch mod.  

The mid switch mod really gives this circuit a lot more range.  The diode switch is also interesting - with the octave off, one diode remains in the signal path.  The diode switch bypasses this diode for a slightly different sound.

Apart from the 10uf from Q3 to ground, all other capacitors can be replaced with 1uf electrolytic or poly caps.  Might save some space, or maybe you prefer polys over electrolytic in the signal path.

My only disappointment with making the Foxx, is that I can't replicate the incredibly seventies looking velour stompbox enclosure.

Or something a little more traditional in terms of size and where the wires leave the board.  I could have made the board smaller, but I was going for something with plenty of room around components.

  1. Nice layout. On the Aion version, the mid-switch makes all the different. I'd recommend this to anyone on the fence. It's the best octave fuzz I've built.
