I played a fretless for the first time last night at my lesson. I had mentioned to my teacher that someday Id like to try a fretless to see what its like, so he brought his along last night. I thought that I would be much more lost and intimidated than I actually was. The sound and feel was just amazing. The only way I can describe it is sleek and elegant. Now I know what mwah(sp?) is. I suspect that mwah can be addictive. As I get more proficient on bass Ive been wondering about getting a five string or trying a fretless. For now I must say, I am VERY intrigued by a fretless. I can hear some wonderful opportunities for using it at Church.
