Offboard wiring - Excelente!!!

A few people have commented on posts asking about offboard wiring. I use a daisy chained power supply, so for things I build for myself I rarely include a battery snap unless it's a positive ground effect which can't be daisy chained with more common negative ground pedals.

This should help people who may be new to the hobby to see where all the wires shown on my layouts need to go:


This is a less common way of wiring the switch, but it's my favourite method now because it grounds the board input during bypass which will prevent noise bleedthrough that you can get with some high gain circuits.

If you want to include a battery snap there are other guides out there such as Beavis Audio's which is excellent.

For pot numbering I stick to this convention:


A lot of the pots I have stocked up on were bought from Futurlec and have PCB pins, so I use this method to solder up the pots which makes it much easier:


A small 5 x 2 piece of vero board is great for this, makes linking pins much easier or even adding the odd component to the pot if it would be convenient to. Another advantage to this is that the board seems to act like a heat sink so very little heat is transferred to the pot avoiding potential damage.
