I've got the following 4 string roundwound sets I tried briefly but did not like and would gladly swap for some strings that are low tension, light gauge (95 or 100 on the E string) and have a deep tone that is not bright on the g string or specifically for a set of GHS Precision flats: Used on a P Bass: Oasis Flex Core - used 10 minutes - 45-65-85-105 D'Addario - 105 set Warwick Black Label - 105 set
