Hi Edward,
Yes, I think there is some stigma associated with being a new seller. If you have some good buyer's feedback it helps, but I think you will lose some value on the first item(s) you sell. If you're not in a terrible hurry to sell your bass, you might dig through your collection and find a dozen or so CDs, video games, or other small items that you can sell on eBay.
Also, make sure that you can take PayPal payments as a new seller. It will be less important when you have a few good sales under your belt, but it makes a buyer feel more comfortable than sending a money order to an unknown seller with no record. If you let the buyers use credit cards with paypal, it will cost about 3% in fees, so make sure you factor that into the cost or state in your auction that the buyer must pay any paypal fees.
These are just my eBay observations, they may be right or wrong, but I am comfortable with them. Do some reading and make sure that you understand how not to get burned. There are just so many scams running right now.
Finally, before you go to eBay, post some better pictures on your sale thread here and give the locals another shot! You may end up making an easier sale than going through the eBay hassle.
good luck!
