Modified Kay Tremolo

Custom order for Damien from Switzerland, a modified Kay Tremolo. Started out as a normal Kay Tremolo but a few things just didn't sound right to me so I waded in and modified the circuit! First I replaced one resistor in the circuit with a preset potientometer which allows you to determine the base speed of the pedal (the audio example shows the pedal set to the fastest it can go, open it up and turn down the pot and you can get slower base speeds). I had major problems with the amp stage (too much distortion) so I simply got rid of it leaving just the bare tremolo circuit, a much cleaner sound! The 2 controls are blend (mix between dry and wet signal) and rate (Tremolo speed). Audio example here.
