adriaan, yes. I do use the truss rod approach too. I lower Riiiiiiight before the buzzing point. This reminds me that the neck IS wood, so temp changes is another variable. I keep the bass in the case until I decide to play it. I live way up in the northeast (Massachusetts), so the temp ALWAYS change. No steady temps here. So, we have to make adjustments. Funny. The bass tends to be flat, so I have to use the tuner to bring the E-A-D-G back in tune, which means the neck it slowly bowing but it's hard to see.
