Welcome Mario, I too have an Epic. I was not in the market for a bass, let alone an Alembic. I didn't know anything about the various current and past models available, I made no informed comparisons. All I knew was that Alembic was the bass that Phil Lesh played, that I couldn't afford when I was a teenager in 1976, when I bought my first bass.
I simply encountered an Epic in my local used shop, and was smitten immediately, before I even knew the brand. After playing it unplugged for 15-20 seconds I found myself thinking, this has got to be more than I can afford. I would visit it weekly, thinking each time that I must be glorifying my memory of this instrument, it couldn't be as sweet as I remembered it. Only to become more attached with each encounter. 8 months later it was mine.
I can imagine the higher priced Alembics having prettier wood, different tones, and maybe someday I'll own another, but I can't imagine any one being better than my Epic.
This was my long winded way of suggesting that you CAN'T GO WRONG with an Alembic.
Peace, JBY
