Fluorescent lights generate radio frequency noise which can interfere with high gain circuits like this one

Ok. Maybe some schematic modification can solve this problem?

Put a 22pF cap between the input and ground. Keep the leads as short as physically possible. Even a millimeter or two will keep it from working.

to solve this problem i choose other transistor Q5. 2n3904 have big noise figure = 4 (in datasheet). i choose bc557bg (this transistor have noise figure = 2).
With this transistor i cant hear radio and other noise. May be in perfect find similar transistor with good gain.

Shielding the enclosure with copper tape and properly gounding it was a PITA, but totally took care of any RF problems, even under shitty power, and being 100m from a radio re-transmission tower.

Just a fast one, can I see the Kill switch gusts? I'm guessing you just put a jumper from hot to ground or do you put in a resistor, I don't want to damage my amp or pedals... but I think the volume control on the guitar dose just that, run off resistance to get less volume
