Here's the brief. 3 pedals for running into a clean (sacrilege I know!) bass spec plexi amp into a 2x12 with M65 Creambacks. I want suggestions for 3 pedals in total - one low, one medium, and one high gain pedal for use with this rig. I guess another option would be one or two low gain pedals, with one medium gain pedal, and stack them for high gain sounds. Either way must be able to achieve low, medium and high gain sounds from whatever combination of 3 pedals you suggest. When I think low gain I am thinking 60's sounds, medium 70's, and high 80's and 90's type classic rock and hard rock.
