Dispense with the volume control

[wibblywobbly]

All boards have a volume control, and we all plug it into a 3 pin socket.

The volume control is a potentiometer that allows the volume to be increased when the knob is turned, and everyone turns the knob to 11 and leaves it there.

Depending on where that potentiometer came from, the quality of the sound will be affected by the quality of the potentiometer, and in the case of an HL volume control it isn't at the high end of the market.

If the potentiometer is taken out of the circuit then the signal can be at full volume, without any such complications.

How do you do this? It is simplicity itself.

Get a 3 pin plug, or cut the one off the volume control, and leave an inch of wiring on all three cables.
Strip the insulation off the ends of all three.
You only need two of them.
In the case of an HL volume control it is the two on the right, when the raised moulding on the plug is facing you.
Just twist the cables together, solder them, snip off the end wire, and plug it back in. Pop a piece of heatshrink over the bare ends for good measure to ensure that if a cable comes loose anywhere else in the tank, it doesn't cause a short circuit.
All other boards should follow the same configuration, but if you want to check just hold the bare wires between your fingers, the signal will pass through your body and complete the circuit, when you have sound, those are the two wires.

This mod will not give you different sounds, but it will improve the clarity of the sounds that you are getting.
