Booster circuit getting some radio interfirence

[DonLee]

Hello everyone  been working on the Vox treble booster  learning a lot from my my first build I am getting radio noise in my circuit mainly I think at the input specialy when I touch the input cap at  beginning of the circuit not sure what to do any suggestions .

A small (47p) ceramic cap from input to ground may help.

shielded wire on the input...

inner core from switch to pcb in....outer shield wire to pcb ground, other end of shielded wire not connected, but taped or heatshrinked so as  not to touch anything else...

just my 2p...

You might try this right off the input jack.  R1 could be 1K and C1 be 10n to limit bandwidth to below 15kHz.  (22n would limit below 7kHz).
