Kevin; since you're asking why you didn't get a bid on your bass, I'll try to help with some suggestions. I look at a lot of Ebay Alembic listings (but I'm trying to cut down ). It has been my observation that pictures can make a big difference in the success of a listing. The pictures in your listing did not really show the beauty of your bass. For instance, many listings have pictures that you can click on to get a larger and more detailed view; yours did not. The picture on the top left, in addition to being small, is a bit dark; it doesn't really give the bidder much information. The picture on the top right is the only picture of the back of the body and the back of the neck. It looks to me that this bass may have an exceptionally nice looking Mahogany body. But it's kinda hard to tell from the picture and I've looked at a lot more Alembics than have many folks that would be in the market for this bass. If the picture was a good bit larger, I'm guessing it would be a big selling point. Also, an additional picture of just the back of the body would be nice. The picture of the headstock is not exceptionally clear; you can barely make out the logo. The picture of the front of the body does not show off that wonderful looking grain. This picture should be the highlight of the listing, but instead it makes the finish look dull. I'm guessing it's at least partly due to the glare of the flash. The flash glare makes it look like the bass hasn't been polished recently. A good picture here would show off that really nice grain.
Also, when you do a search under musical instruments for Alembic, your listing does not show a picture of the bass like many of the other listings do. I nice body shot here would draw attention to your bass.
I don't follow the prices of Epics closely. I do know that they stay fairly steady and trade fairly often. I'm guessing that the prices of four string Epics in good condition generally run $850 to $950; and that the prices of five strings run higher than that. Your bass appears to be in very good condition; so I'm thinking that $1,000 for your bass is probably a good deal; but again I don't follow the prices on Epics that closely. (Last week an Epic four string sold for $1,632; which is historically high, but it did have a nice picture of the top and included a hard case.) The lack of a case could be an issue for some folks, but it's been my observation that a lot of Epics have gig bags rather than cases. A picture of the gig bag might help. My guess is that if you can get some better quality pictures, you should be able to sell this bass for at least $1,000. A little patience helps too; some weeks there just aren't many buyers looking for what your selling. Over the last few months, prices for an Alembic F-1X have ranged from below $400 to well above $500; an increase from the low end to the high end of more than 25%. So timing is a factor; and patience helps.
