Awhile back the bridge pup on my tele quit working. The guitar is a nashville deluxe tele with the tex mex pups. I replaced the bridge pup with a seymour duncan jerry donahue signature after hearing good things about it on tgp. Ever since it sounds great except when I switch to the setting(#2) with both the bridge pup and middle pup. Now it sounds thin and you have to crank the guitar's volume knob to get it to sound the same. Can anyone help me with this? Is the seymour duncan pick up not matched or is it wired wrong? Before the original pup quit working every position was balanced.
