I suppose that you could do without amplification. I always felt that the less work your hands had to do to play the bass, the less pain or overuse that your hand muscles would take place. If you have an amp, I would plug it in. If you don't then don't pluck the strings too hard.Jeff, if I start your courses, how important is it to be plugged in? I have a Rogue Beatle bass that's a 31" scale. If I later go to 34" bass, will that be a big adjustment? Thanks in advance.
A 31 inch scale bass would accommodate what I prepared for people to practice. If you went to a 34 inch scale, it will only add more frets to navigate as you ascend and descend the neck in the chord tone lessons that I wrote. But, I feel that you will be fine with the shorter scale.
