(I'm new to TalkBass and already posted this, but in the BG section by mistake, so I will re-post it here in DB.) ..... First of all, I'm just getting interested in bass, so I know almost nothing about a bass. I've been a mandolin player for quite a while, but never tried the bass. I have an opportunity to trade a mandolin for a bass, but I'm not familiar with what the bass I'm interested in is worth. So far, this is what I've been told: It's a 1956 American Standard and has recently had all new hardware, a neck reset, new adjustable bridge, adjustable end pin, new tuners, new tailpiece and new strings. The guy who owns it is a bluegrass musician who plays professionally. He claims the bass is a "monster". Any feedback, good, bad or otherwise would be greatly appreciated. Thanks.
