Charlie Griffiths of HAKEN, the owner of #53, realized that he didn’t need a tone pot and that he also needed to move the volume pot out of the way – and in place of the old volume put a “blower” switch. This switch sends the bridge pickup in humbucker mode straight to the output jack, bypassing the 5-way switch and volume knob, for a “solo mode”. The switch itself is a push-push switch that simply protrudes out of the top.
Mounting one, however, is not necessarily the most straight-forward operation… What I came up with was a bracket that is wedged in between the top and bottom inside the control cavity, to secure it depth-wise, and that is secured in place by the volume pot + a small screw that holds it in the side.
The hole for the volume pot:
