I think the one I have, which is not a Wolf copy, plays as well as any guitar I have played. I am not going to say that Phils overall quality is just as good as Alembic's (especially in appearance, Alembics are definetly far more elaborate in appearance for the most part), but it is certainly comparable. Its hard for a one man shop to keep up with a company that has been making guitars for a very long time like Alembic has.
Id say its a personal preference thing. Phils guitars play very well and to me are a great deal for the money. He also does not usually use active electronics so if you want the Alembic sound then its not gonna be what you are looking for. If you want a real nice guitar that is very reasonable in price then his are about as good as you can get. Id wager that his prices will be going up very soon. He has a huge backlog of orders and he is now selling everything he makes. It took him about 6 months to make my guitar, which isnt half bad. To me you cant get a better deal on a custom made guitar if money is an issue. If you have an unlimited budget I would shoot for the stars with a real high end guitar, but if you want to keep it reasonable then he is a really nice option.
