The tension of the strings bends the thing upwards:

...resulting in a very bad break angle over the bridge:

As if this wasn't enough, with the plate under the bridge, the pickup is very far away from the strings. I thought it wouldn't be too bad, but the P13 hasn't got a very high output to begin with. Now the whole guitar is very silent and dull sounding. I need to get that pickup closer to the strings.

I think I'm just sell it, get a Gretsch G5715 and drill the Certano just straight in. Or I go full on modding on the Silvertone, put good tuners in, change the pots for something with a useful taper and change the fixed cable for a jack socket. But, you know, it would make it a cool player, but on the other side, this guy is 70 years old...
