I took delivery of an Ibanez GSRM20 Mikro short scale (28.5") bass today, and I was immediately delighted by how easy it is to play compared to my standard 34" basses. One thing I noticed is that I can now use my strongest three fingers (index, middle and ring) to stretch across four frets... a habit I formed when I first taught myself bass many years ago. I've been re-learning bass over the past couple of months, and I've been trying to force myself to get my pinky to do its duty on the fourth fret as part of the 'one finger for each fret' style of playing. However, it's been an uphill battle... that recalcitrant little finger has little strength, little precision and seemingly little interest in doing its share of the fretting. Anyway, I thought I'd ask you experienced bass players. Should I stick at trying to force my pinky into the action? Or do some accomplished bassists primarily rely on their three strongest fingers?
