Does any such pedal/ effect exist? I am reasonably new to bass guitars and completely new to effects pedals - i have never used one and have zero knowledge on the subject. The reason I ask is that I can see the benefit of using flats and rounds to get a varied range of sounds depending on what a particular song calls for. So I am torn between having 2 basses - 1 with flats & 1 with rounds, or just having the 1 bass with say rounds on it but using an effects pedal to switch to a 'flat' sound when need be. I have had a search around on the forums and I can't find anything related to this - however typing in different combinations of '"roundwound flatwound/ rounds flats" brings up lots of unrelated hits. Any help or advice would be much appreciated - thanks.
