Well, I went and picked it up. The strings are a bit rusty at the bridge, but the instrument is in very good shape. A couple dings, but nothing I would call severe on a 15-20 year old bass. I made a little tweak to the relief and bridge height that has it playing very well. For a bass with old, dead strings it sounds great. It wants to run with the tone most of the way up or wide open, the bridge volume dimed, and maybe halfway up on the neck pickup for a little meat. Maybe with new steel on it, it will have more of a vocal range without pushing the limits of the electronics. The OBLs sound quite clear for humbuckers, very well defined.
I will put it through the paces tomorrow and compare it against my SC run through a POG. When I first heard the POG, I thought it sounded really cool, but had never actually played a real eight to compare it. Now that I hear a true eight, I'm not sure there's that much difference in the tone available. Since my SC is a custom neck dimension that's a bit tighter than standard, I'm finding it a bit spaced out to play the Hamer eight. Also, it's set up with the octave strings above the bass strings. This favors pick playing and I'm really a fingerstyle guy 90% of the time or more. There are some songs that sound *really* cool with it though. I am definitely getting ideas already from noodling on this thing.
In short, I'm on the fence about whether or not to keep the bass. I have 15 days to return it, but I'd hope to make a quicker decision so as not to take unfair advantage of the store policy. If I decide not to keep it, I will make it available here if I can do so at a price that is a good value for someone and is at or above what I have into it. Since I'll be looking to make a quick decision, please email me if you might be interested or know what the street value of one of these things is.
Thanks, everyone, for all your thoughts!
