OK, I have finally broken down and saved up my bucks and am ordering a Read Purity. Yea! But I have a question for all of you. Jack (Read) says that I have options for the tubes. Any suggestions? Should I upgrade to the Telefunkens or go with the "stock" ones or is there something else I should consider? Does anybody know what ones were in the preamp played on BassTasters (which is an awseome site, BTW!)? Just curious. I am looking for that "really warm tone" with as few bells and whistles as possible. I play both slap/funk and jazz bass mostly through Bartolini pickups with active circuitry (both 4 and 5 string). Any and all comments are greatly appreciated. <p> Groove on!
