Been reading this and thought I would throw in my 2 cents even though I am one of those freaky skinny string dudes
I do have quite a bit of experience in buying and selling guitars, I tend to rotate my guitars like people do socks.
So first everything formites like Jack and Rex have said are so true, it is just harder right now to sell due to the state of the economy, you really have to be willing to take a hit right now on some stuff.
Also it is a beautful Bongo but a nitch one at that, its not a Dargie or Redwood or EVH etc. plus I am sure the fretless is only for a select few plus we all know a piezo isnt cheap but sometimes hard to recoup that cost.
now for my tips, first as much as I hate paypal you must offer it, second at best hope for a split in the fees or ask for an echeck only costs you $5.
Second you must offer it up for international sale, if i did not do that I would be stuck with alot of guitars or would not have been able to try new ones.
It really isnt that much of a hassle, USPS rules vary by country as far as size and the amount you can insure it for, I prefer other carriers but if the buyer wants USPS its at thier risk, UPS while more expensive is a safer route but bottom line offer it to all.
Third be willing to negotiate, dont give it away but if a counter offer comes thats reasonable accept it.
And finally fourth, as much as I hate Ebay as well it can be your friend, i much prefer to sell within the forum but sometimes thats not going to happen, i generally give the forum 2 weeks with one bump and then off to Ebay.
good luck and congrats on your new addition, nice name by the way.
