I spent some time looking at your Dean Jeff Berlin bass today and was wondering if you are obligated to only play that bass? and if you do play other bass's what ones do you prefer? I owned a thin neck bass and did not enjoy it at all or I would consider your bass (which is a steal for all the extras it has).
It is an obligation that comes when you endorse a product. But the Jeff Berlin bass is far and away the best bass guitar I ever played. So sticking to this instrument is only a pleasure for me, not a hindrance in any way.
