I’m working on layout for a new tremolo. Before making the PCB I’m laying out the box. This way I can design the PCB to work with this layout.
This is a tremolo based on the tremolo used in some older Fender amps. The circuit divides the signal into low pass and high pass and cross fades between the two signals. It has a great sound, it also sounds like a phase shifter.
Here are The designs I came up with. Note that the colored circles show the outlines for typical knob diameters: 6mm, 12.5mm, 14.5mm, 18mm, 23.5mm, 25.4mm, and 37mm.
