Swapped my 110 gauge 77s for 55s, looking for a bit warmer tone but still smoother than rounds. They're tuned down a whole step and even with the heavier tension set (105) they don't seem to stay in tune. Could that be because the tension is too low (I don't think they make 110s in the pressure wound), or some other reason. Anyone else have this problem? If it's a problem inherent with the 55s in drop tuning, are there any pressure wound or half wound suggestions? I like the sound of the 55s and how they play, just not retuning every 10 minutes.
