There's a big difference between a custom bass, and a bass that gets personalized.
Personalized basses has the traditional Alembic shape(s), but are personalized with insignias. For example: initials, names, symbols, images, and/or personal quotes -- are personal insignias.
If the owners initials on the bass, are different from mine, I am in a favorable position as a buyer, to request a remedy for this conflict, of a different initial(s) from my name... and guess what...? there are possibly other potential personal insignias reviewed on the bass that conflicts a buyers personal preferences as well.
How will you as a seller, address this concern?
Custom shape basses are also hard to sell because they don't stick to standards consumer(s) are accustomed to viewing and conceptualizing. Some shapes may be too plain, or too many bells and/or too many bells & whistles. Again, how will you as a seller, address this concern?
So, in short -- I believe you should keep your bass because its personalized, and it has a unique custom body, and that means lower re-sale for those who smell blood.
So, if you don't have to sell, (like I said...) get that bass outside and on stage and play it.
Also, its hard to sell something, if you don't believe in the value. Custom basses are much harder to sell, because people are not always a-custom to change, nor do they understand your values, and it's not in their interest to care. A buyer will take advantage of your custom items, and use it against you, to get the most lowest price.
In real estate, people add pools to their backyard, thinking it will raise the value of their home. Most people will go for the home without the pool, even if the desire for a pool manifest, they simply may not like the shape of your pool; and find it best, to look for a lot to define their dream pool.
Also, as someone who owns a radical looking Alembic called: The Toma_Hawk, I designed my bass to point-blank solve a problem as a light bulb or as a ergonomically made Herman Miller chair... and it has no personal insignias. I have no plans what so ever, selling this bass. In fact, this bass was never created for selling. In my mind, this bass is like an extension of me as a specialized musical limb or a personal and magical broom-stick, which only understand me as the driver, like in the Harry Potter movies.
KEEP YOUR BASS, AND PLAY IT!!!
Peace and Love,
