Hi! I have a Sire Marcus Miller P7 (5 string, Swamp Ash body, Maple Fretboard. P-J pickups), & it sounds tooo Bright!! I bought it just October 2019. I tried semi-heavy gauge Nickel plated Daddario strings, increasing the action of the strings and Nothing seems to work!!! I just don't hear Low end from the bass!! Even the B & E strings just put out a lot of hi-mids. Absolutely no warmth or lows to the sound in Active/Passive mode even with the Tone at 0%. Any suggestions for punchy sounding pickups, warm sounding strings? Anything else I can do to hear "Bass" from it Please help.
