I play a Yamaha RBX-775 into a Sansamp RBI - Crown XTI1000 - SWR Workingman 4x10t. Sadowsky Bright Nickel Blue Label Strings. I can't really find a tone I like and on a whim I tuned all strings down a full step. After that, I started to really dig the sound I was getting. I'm assuming the string tension is what did this miraculous change. Why is this? I would really rather not leave it in this tuning, but I doubt I'll be able to lower the string tension enough by adjustments.
