this is not a cymbal that you will find annywhere because it is a custom-made prototype cymbal from sabian. if the designer of the cymbal finds that the reaction from the so-called celebrity drummers is good, then it will go to print as 'mainstream' cymbals.
mike portnoy's max stax was labelled as such before being mass produced, as with all other signature cymbals from sabian. this is not a line, it is simply a prototype that, oddly enough, shouldn't be in that person's possession unless he got it off ebay or custom ordered a cymbal.
think of it as mark I or mark II before the final product.
