Since I had time and had never opened it ... Well, I was encouraged. At least in the variax 600 model the pots are mounted on the pickguard, I observed that right next to the guitar model selector it had a metal point so you know what model you are, coinciding with the point on the model name, Well, it occurred to me to place a red led in that hole already made to do the same function and to see the Bank where you are playing even in the dark illuminated and this is how it turned out, I really liked the result, it gives you a more sophisticated appearance.
Well nothing so far my entertainment today and my new mod variax 600. The led works both with batteries and with the cable.
