I have a Triple Rec pre 2010 with series mod. Just wondering how the studio preamp would sound compared to the rectifier? I thought the studio preamp was more of a Mark style sound which is what I want considering selling recto for a power amp and getting preamp. Any thoughts? Suggestions? Want Master of Puppets tone without having to spend too much. My Triple Rec with Helix [Running Was and a Tubescreamer in the Helix] does pretty well but wanting better. Thinking Studio Preamp with a Poweramp and my Helix would be better.
