I use a Fender P-Bass Deluxe 4 string. The band im in drops to C, so my tuning is CGCF. When we first went into the studio i used 65-120 DR strings but beacause i play aggresivley there was alot of pickup "farts". I Then went to using a 125 and 130 as my low C. Shoould i use an even heavyier gauge or re-set up my bass. Or should i use different brands or what. Any advise will be appreciated.
