Hey Nevvy.
please use the "edit" function to add something to your post, way easier for people to read the forum if you're not creating a new post for every sentece.
and to answer (some) of your questions....you're using an ampsetting you saw on a studio video of a production that didn't even have the 5150 on it....that setting wasn't used....
and even if it would have been used, you're using a cmpletely different cab (and gutar and fingers etc), it makes ZERO sense to just copy those...at least if you want a similar tone.
Also: that 808 belongs in front of the amp, not in the loop!
AND: you'll NEVER get an awesome tone by copying someone else's settings on your equipment....if you want an awesome tone you'll have to learn to dial in your own amp so that it sounds awesome in YOUR room with YOUR guitar, YOUR cab, YOUR playing etc
Like i said, i'm new to the forum, and it wasn't a new post for every sentence if you look carefully; i was replying to individuals (1 post per reply, not per sentence!) besides nobody has posted on it in well over a year.
I know the 5150 wasn't used on THAT production, i didn't even say what era i was focusing on :S. but they often use 5150s so just hoped those settings may have been used at some point as they are KILLER.
The cab may be different (ie. wood, dimensions) but the speakers are still V30s and MY guitar is actually one of Adam D's old ones (thats right you read that right!) so its about as similar as you can get. The settings on the video i have dialed in are awesome and sound awesome, maybe i need to purchase an attenuator to push the valves but i still believe it will be largely due to production on Protools.
My 808 IS in front of the amp, its in the effect loop of my BOSS NS2.
Anyway, thanks for your opinions.
