Zombie thread time .
The Gretsch GAS welled up again to almost unbearable proportions, but I reined myself in, realising that I’m only playing to please myself at the moment and the Casino Coupé is a more than capable guitar. Since the OP, I have fitted new pickups, changed the knobs and made a couple of other aesthetic changes. However, just like the factory fitted Bigsbys on other guitars, with the same break angle over the bridge, tuning stability is questionable. In order to keep the GAS at bay and address this tuning shortcoming, I bought a drop in replacement, roller bridge. Why, oh why did I not do this at the get go? I can attack the Bigsby without fear of a discordant result on return to the resting position. The cost of this miraculous upgrade, less than £22, including delivery. Happy days!
