alright...so i just got back from the store where i was going to buy some sovtek 12ax7lps's for my svp pro. after talking to the guy, and getting a price, i asked him about his return policy, seeing as these tubes are defective much of the time. i told him about lord valve and how he tests the tubes and all that. the guy finally told me to save myself the trouble and just order from lord valve, rather than going through the trouble of trying to return tubes and whatnot. so now i've decided on getting tubes from lord valve. after reading your experience with the ones you just got, i'm thinking about doing the same thing. i play rock (mostly), but i want to get tubes that won't distort too much. i'd like a clean tone. i play alot of stuff with chords and would like to have a smooth, balanced, clean tone, that's real "warm", and "thick". what do you think: sovtek 12ax7lps, or some other combination?
