I just purchased a new fender rumble 500 combo which I am playing a new Fender P bass through. I purchased the amp because of the very good ratings it received. Overall I really like the clean sound along with overdrive setting. The only thing I am disappointed in right now is the vintage setting. I expected that sound to have that dirty vintage tube sound like in the song by “Yes” in roundabout or somewhat close to that. I have adjusted the mids, bass and treble to try to achieve something but I cant even get close to that sound. When I activate the vintage setting it does not seem to change much at all. I have looked online and some users are right on the money with that vintage tube sound. I guess my question is if the amp is not defective could it be the P bass just cant produce that effect. I don’t have thin skin so let me know your thoughts, it could be user error, need some help.
