Hi, I am a music student studying for grade 8 recently one of my tutors has told me that he thinks a lot of my problems with bass playing is that my bass is too big for me. I use an American Fender Jazz which I love! But I get a lot of hand pain from it and bruises on my shoulders. As the body of my bass is bigger than mine it sounds sensible that this could be affecting my technique, especially when reaching the lower notes I have to completely stretch my arm. Does the size of bass make a difference and are there any smaller bass that sound anything like a jazz? Thanks
