MOD Golden Mask1+ to GM4+ - Add ground/ audio tone / frequency

[gandolfi]

Hello,
While strolling on the Net I found a golden mask PCB 1+ and 4+. This would be a detector under the name of MAGNUM on Geotech.
Apparently it's the same PCB but it lacks knobs. 50K for audio and 10K for ground.


PCB



GM1+


GM4+




Do you think that we can add the ground effect, the frequency setting and the tone adjustment just adding these knobs on the device?

thanks
