Yup, the PBs really bring something different to the party ...glad you like em on your 312!
Now here's the next step in the tonal experiment: try the very same strings in medium-light gauge (12-56). The GBE strings are from the light set, and the EAD are from the mediums. Bigger lows and tighter bass yet. It shifts the tonal "balance," if you will, and makes for a fuller, rounder tone. And like all tonal experiments, only you can determine whether it's a hit or miss. FWIW, I love them and these have been my favorite set on acoustics (of non-taylors in the past, as well) for mannnny years. It has all the sparkle of the elixir PBs, but with added bottom-end ooomph. For the GC and GA bodies, this set in PBs are a real plus, IMHO.
