What strings do Thumb players use most? I am finger style player, support bass player, not really a slapper or solo act. "Nothing sounds like a Thumb" so why mess up that beloved tone with the wrong strings? I have Warwick black label set on it now and really like them in the week they have been on. What do you use? There are too many makes and models to make this a poll. My cupboard currently has Rotosound 66, Labella steel wound series and nickle plated series, Sit exposed core, DR high beam, Sunbeams, Rotosound 99 PSD, Dean Markley helix all have not been tried yet.
