Just to follow up - I've had this T-40 for almost a month now and I just can't get over what a fun instrument this is. The only downside is that I have (at least temporarily) pushed my G&L aside.
I am neither good, nor do I really aspire to do anything more than play along to some of my favorite songs & jam with my kids, but I'm getting better because I have a hard time putting it down.
The actual downside: When I travel, I like to take a bass with me...I may need to hire a Sherpa to help lug this T-40 in its case.
