Hey guys, The 5150 III is a hard amp to get a bad tone out of, we all know that. But how do you set yours, and what kind of pickups and pedals do you have in your chain to get your tone? My blue channel (5150 IIIS) is set as follows: Gain: 2:30 Low: a hair over noon Mid: 12:30 High: a hair under noon. Presence: 09:00 Resonance:10:30 Red channel: Gain: 11:00 Low: 12:00 Mid: 2:30 High: 11:00 Presence: 11:00 Resonance: 2:30 I’ve got my Formula loaded with Black Winters, and those do a lot for my tone, so it makes me roll back on the gain and highs more than with other pickups, depending on the situation. I keep my mids past noon because COB is my favorite band and they use tons of mids. Love the tones I get. Been on a Slayer kick recently and really loving the punchy tone of the blue channel.
