Some guys love them. My sample size is extra large. 30 plus J or pj basses. If my sample size was a couple I wouldn't be so adamant. Chambering was introduced by him to reduce weight, especially for alder wood. After many of his players tried them, they liked the tone. I was one who thought differently. My 3 favorite of the 30 were metros. All just under 9lbs. Absolutely stellar
