Well a while ago I made a thread about the same thing, and it seemed a few people were going to be trying some tubes out (Tom B comes to mind) so I thought i'd ask again before buying up. The gain II in my V8 is very bright, and whilst it can sound nice, I find it contrasts with my gain I setting too much. ie: My gain 1 setting will sound deep and thick, then I switch to my gain to and it's bright (it then doesn't fit with my previous sound). I also find when the deep switch is in, the channel will still be pretty bright, but it also seems VERY scooped and can easily get lost in a mix, or even on it's on it can become harder to distinguish notes when playing fast. So i'm looking for some preamp tubes to fatten my whole sound up, and also make it a bit more aggressive (if possible). I may replace all of them, so if any of you V8 owners think certain tubes will fit certain Vspots then let me know. For those of you who don't know, theres 7 preamps tubes in there.. So what do you guys reckon a should go for? Also, where is the best place to buy them from (Especially NOS tubes) that will ship to me in Aus (and I can have confidence in them packing well etc). Thanks guys. PS. Sorry if the threads a bit vauge and spelling is bad, i'm reeeallly tired and heading off to bedy byes right now.
