I know this topic has been covered, but it has not been covered in detail. I know that pressure wounds are roundwounds that have been compressed and flattened, and ground wounds are roundwounds that have been ground on the surface. Fairly obvious differences in construction. But, the differences in feel, look, and tone have not been addressed. I am mostly concerned with the differences in tone. Here are the strings I am considering: Ground Wound GHS Brite flats Ken Smith Slick Rounds Pressure Wound GHS Pressurewounds Ken Smith Compressors I am especially interested in which strings are better suited tonally for a fretless bass because I am getting a fretless SX P bass soon. Thanks!
