I have an ibanez rg series 7 string with sd blackouts, fender 212 r, and boss me70. Im trying to get a machine head sounding tone out of what i already have. Any suggestions/eq settings or what fx to use to help achieve that tone is appriciated!
What you need...

(wait for it)

...is a new amp. Srsly
I know i need a new amp. Im saving up. Thats y i specified that i wanted to try to get the tone with what i have
Not sure on how to do it with what you've got. Best to trust your own ears in all honesty, and if you honestly can't get the tone maybe it's just not possible to get the right tone out of it with what you have?

Also if you want something that sounds like a 5150 check this pedal out.
