[quote name='Zach' post='1009913' date='Nov 2 2010, 06:55 PM']can i second the previous question. will it start sounding like a mess if i start subbing in chords on bass whilst the others are playing a standard progression?[/quote]
Yes No Maybe - depends on the chord voicings, their note choices, your note choices etc. Recommend you try stuff out in the practice room. If their chord voicings are full of root notes you may clash but, if they are more 'open' voicings, your options are wide open. Learn to hear what's good and what's not.
