I am currently using a Jackson bass with passive but HO pups and a Gallien Kruger MB115 with a bit of chorus from a BOSS pedal. For the most part I really like this sound am happy. However the combo of the Jackson and GK is quite an agressive punchy tone (even though I cut out the mids) that just does not work with some songs like a ballad, country, motown ... So my question is what effect (if any) could bring this set up to a more vintage warm fat bottom end if needed? Ideal would be if there was such a thing as an "Ampeg" effect pedal. I don't plan to change my rig to any great degree and want to stay simple so I am doubtful of any pre amps or rack mount stuff. I understand no pedal will likely totally reverse what my current sound is. But on a few songs it would be nice to have the ability to get a warmer sound with out much trouble. I am open for suggestions? Thanks!
