U3 translates to Uncompromising Quality, Unparalleled Versatility, Unbelievable Sound; and stated as
such represents the primary Mission and
the Values of our Company.
Since the start of his professional career and the humble beginnings of the instruments that bear his name, Master Luthier and SPECTOR® founder Stuart Spector has built a reputation for the highest quality instruments and outstanding customer care.  He's done this the old-fashioned way by building a loyal customer following one instrument at a time. 

Stuart Spector Designs, LTD. is a modest company composed of a select handful of dedicated craftsmen who under Stuart's leadership strive to build musical instruments which embody the "
U3" concept.
Our business philosophy is simple; we feel that success or failure has less to do with numbers on spreadsheets and has everything to do with what the musicians who choose to purchase and play our instruments feel regarding how we do our job.
And ultimately it is that musician's choice of which instrument to own and play that is the prime motivator for dedication to the U3 standard we've created for ourselves. 

We KNOW that there are always other options, other companies, other instruments; but we feel compelled to continue our quest to refine and build the best instruments any musician could hope to play. 

We do this because as musicians ourselves; we understand the personal and very important bond that each musician forms with their instrument. Through our own journey to find "the one" bass or guitar that makes us feel like we're home from a long journey every time we pick it up; we are honored and proud when other musicians feel this way about one of our instruments.
In that moment we find the justification for all the times which have tested our resolve and we are spurred ever forward to continue to refine, improve and evolve our basses and guitars.  It is for you that we will always endeavor to keep our guiding principles of U3 in the forefront of all we do.
Thank you for choosing SPECTOR® basses and guitars.

 USA SERIES NS-5XL™
Neck-Thru NS-5XL™ with Exotic Water-Cured Redwood Burl Top.  This was the first limited-run Special-Edition USA Series™ bass.  Instead of being a series of basses that were made exactly the same, you could choose to have any USA Series™ bass topped and finished in this rare wood.

Made from a log of Redwood which had been submerged in a stream for over 100 years, the wood had been "water-cured".  Creating a near-holographic effect in the wood grain and providing a rich-warm tone, the only log of this felled Redwood tree was purchased by Stuart and some 20 guitars have been made from it in the past decade.

No more of this beautiful wood is available and because of the unique circumstances of its creation none will likely ever be available again!
