The Gibson Alex Lifeson Axcess Les Paul is one of the best made guitars I have owned. It is a bit on the heavy side, but that is typical for this style of electric. I believe they did carve out some of the interior to modify the sound to make the most effective use of the "Life-O-Sound" piezos. The use of this mode is more complex than one might expect due to the need to have two ¼" outputs in use at the same time. Furthermore, the use of the topside knobs is not intuitive as they have multiple push-pull combinations to achieve the mix between electric and acoustic. Regardless, this is a fine instrument that I will never part with and pass to my children some day. If you can get your hands on one, you will never regret it.
