Hi!

It works...randomly...depending on where you touch with the probes, the leds may light off. It seems a layout problem. But even when it worked, with 4k7/470R it light up at -14dbu.

The scope probe will introduce a high impedance DC path (1 Mohm) to ground, also some very small capacitance.

Don't only half-ass tune your drums. Visit https://circularscience.com to hear what properly "cleared" drums sound like.
