I had one when they where new. And thought it among the best sounding JJ pup basses with heavy overdrive and pick playing, that Id ever heard. But I dont well rememeber how I rated it for growl factor. Hoping some could give their opinion on the growl factor for them. Got an opportunity to get a nice condition used one and thats only thing holding me back. I do remember I liked the B10 voice better then the higher up models that had emg select pups JP and JJ configuration. Thanks for any input from owners/former owners on B10 growllyness. Note: description for B10 & B2 are reversed in catalog pic.
