As a matter of fact, I drove 4 hours yesterday to buy a guitar - a 1972 Martin D12-35 that is exactly the year and model I bought new in 1972 but sold in the 1980's. I always regretted selling that guitar. So, when I found one exactly like it in good condition at a (relatively) reasonable price, I could not resist. I will be back home tonight and will try to get the Panjo system updated at that time. Sorry for any inconvenience.
