When I think of crappy instruments, and in this case basses, I think the crappy ones have very few sound choices and they sound dull. I had a toy bass from sears that sounded like donk, donk, dang
But there are people who could take this same bass, and play the heck out of it... This is a true master. S/he can find the beauty of the sound, and bring out the best from it. Although, there are only a few things they could do, they still accentuate the soul beauty of the instrument.
Why 5 string bass over 4?
4 has been the standard but because, we are high on LOWER LOWS AND HIGHER HIGHS, sound is evolving as basses. A 5 string bass player has more options and if they are true masters, they could still play the hell out of a Kmart special by Mattel.
Alembic basses sound good even if you play one note. Two notes even better. On the other hand, playing ONE note on my ?close to being played as broom stick,? or fire wood, sounds bad for anyone unless you are a true master.
