My Washburn EA20-12 is built like a brick sh**house, but it has the lowest and easiest action of any 12 I have ever played, combined with a neck of decent width. Using Gibson lights (10 thou first, 8 thou 3rd octave) it keeps its tune in E once bedded in and even permits tuning down to D if required. I use a Terry Gould or a Heriba capo, when necessary, and don't have any intonation or tuning problems.And, unusually for a Washburn EA (Festival Series) in my experience, it works well as an accoustic.
I've owned and played 12-strings for almost 40 years, and this one is the best so far IMHO. Perhaps I'm just lucky.
But if my friend Rick ever wanted to sell his 1963 Gibson B45-12 ....
