I bought a new round-back Brescian model bass from Upton -- had it made for me with wood I chose, and the finish I chose, and before it left the shop they set it up for the way I would be using the instrument. The bass is a joy to play, and sounds wonderful already. What's not to like? Upton seems to be getting very popular, so there is a considerable wait for a new bass, but it's actually worth it. Nice folks to boot.

Needed acoustic bass guitar strings for a fretless, they recommended the right product for my needs (TI Flats) -- even though they don't carry them. Class act.

Amazing service, amazing people, smiles on their faces. Willing to go above and beyond to service my old instrument (not bought from them) which is now unplayable without the premise of me purchasing a new one or even having them repair it. Great small business, located just off the highway in a beautiful barn. Great experience, would totally recommend!

Upton Bass is an excellent outfit. They go the extra yard to satisfy their customers' needs. Their sales department is personal and extremely helpful in all transactions. I will continue to buy my acoustic bass strings from them in the future.

Upton Bass is great! I haven't had the chance to try their basses yet, but my luthier says they are terrific. I'm on the hunt for a good upright bass, and Eric answered all my questions promptly and was very helpful. I'm still deciding what I'm going to do, but an Upton Bass will definitely be on the list of possibles.

Upton Bass is the place to go for all things bass. Eric sorted out the shipping of my bass to Australia and set me up with an Upton model travel bass. Jack does great setups and the attention to detail was very impressive. Highly recommend Upton Bass. 5 star service. and beyond!

I've found my Fur-ever luthier! Man, these guys know there stuff! Service was fast and fairly priced. In these times of non-existent customer service, it was refreshing to deal with a company that was more than willing to take the time to ensure I got exactly what I wanted. The Luthier was extremely knowledgeable, and very generous with his time "talking shop". I will definitely be doing more business with Upton Bass. ( 15 + yrs pro bass experience, I've seen / handled a lot of basses)
