Frequently Asked Questions

Q: How can I find out what year my instrument was made?

A: The first two digits of all Modulus serial numbers indicate the year the instrument was manufactured. For example, a bass with serial # 930111 was built in 1993, and a bass with serial # 020343 was built in 2002. Modulus began using serial numbers in 1990, so all basses before that time bear only the Modulus patent number.

Q: How can I get a replacement pickguard for my Flea or VJ bass?

A: As Modulus does not make individual pickguards, please refer to a local repair shop or technician to have a replacement pickguard made for your bass. You will need to take your existing pickguard in to the shop so that they can trace the pattern to get an exact match.

Q: What kind of strings does Modulus use?

A: All new Modulus basses are strung with D’Addarios here at the factory. We use nickel round-wounds, gauges .35, .45, .65, .85, .105, .130. For 34" scale basses we use their "Long-scale" string, and for our 35" scale basses its the "Super-longs." Most retail stores sell a similar set called “XL170” which are available in both long and super-long scale length. Sets of Modulus spec D’Addarios are available for sale on our website as well.

Q: What models does Modulus offer in a left-handed version?

A: At this time, only the Genesis 4 & 5 basses, and the Genesis VJ are available in a lefty format. We are currently working to add lefty versions of all Quantums to the list as well, so check back periodically for updates.

Q: Where can I buy replacement hardware and parts for my Modulus bass?

A: Since we need to keep a healthy supply of hardware and parts on hand here at the factory in order to continue producing eagerly awaited instruments, we do not sell replacement parts. We recommend that you contact the friendly and helpful staff at Allparts (www.allparts.com , (800)327-8942) for all your replacement part needs.
