I am going to have the potentiometer changed that determines ground balance....New ten turn pot will go where pin point button is now..To keep the pin point feature, a trigger can be incorporated..Here is the question since I've never used the button in the field...Do you use this feature? Can it be disposed of? Advantages / Disadvantages? I don't really have that much time on the "V", and may still be like the gal that used the choke knob to hang her purse on, not using everything properly ..So before I say "remove", or "keep", I would like the benefit of your experience,..Thank you so very much, Nad
