For decades the tendency has been to go brighter rather than deeper ( I am sure there are major exceptions such as ppl tuning down their 5 str to low A or lower . But I am just an old school player w a 4 string I will continue to work on my brighter tones- growl - burp- presence etc But I find there are times I just want to go back to the incredible power of using a strong Deep Sound with less highs My question is directed towards the HOW of creating deep tones- pros and cons of various approaches I have a two pick up bass First thing o wonder about is which PU do I want to emphasize ? Obviously there are merits to both Tone settings ? A dedicated low end cab? If you haven't done it in a while , it is a kick The other issue is when you do it so much that pitch gets lost Maybe that is not a bad thing? And finally avoiding boom and mud I invite all opinions on this .
