I have a 5-way switch issue on one of my two JTV-69S. The Switch works on the magnetic pickups but only positions 1 and 5 on all models are working. Model 3 is selected for positions 2, 3, and 4 on all of the models. I am thinking that it may be the contacts. I don't want to use DeoxIT D5 on my Variax as I am not sure that it is safe to do so. Any suggestions. I can ship to CA from AR. I used to live in CA but moved cuz' of the wild fires (and poly - ticks).
