I play in a classic rock/middle of the road cover band and I would like to set my Bass PodXT/Variax up to have a half dozen or so essential tones to cover most songs. When rehearsing, I like trying different tones during the song to see which one sounds best. Usually, one of the settings will rise above the others as being the most suitable. I have three that I am using now. A Precision/Ampeg 8x10 setting, a Beatles setting and one called Memphis Bottom, which has the treble rolled off and sounds quite muddy. It doesnt sound good on its own but sits perfectly in the mix with big round notes. What other essential tones might I add?
