McGrath Guitars Bass Builder
Thanks for checking out our Bass Builder! Madelyn hand-drew every part of it, and we’re always adding new options. Design the bass you’ve been imagining, and we’ll build it with premium components and rock-solid construction.
After you order, we’ll contact you personally to confirm every detail before your build begins. Need a bass sooner? Browse our In-Stock Instruments or visit one of our Dealers.
How It Works
1. Design Your Bass: Choose your model, pickups, hardware, and finish in the builder. Want something that isn’t listed? Just ask.
2. Place Your Order: Reserve your build slot with a 25% deposit of your build price, or pay in full.
3. We Review It Together: We check every order for specs and accuracy, then reach out to confirm the details, wiring preferences, and artwork before we start.
4. We Build It: Your bass is handcrafted, painted, and finished in our San Diego shop.
5. Final Setup: Every instrument gets final assembly, full electronics testing, and a complete playability setup before it leaves the shop.
6. It Ships: Once any remaining balance is paid, your bass ships in a hybrid case and you’ll get tracking by email.

Timeline, Deposit & Shipping
Lead time: Most builds ship in about 12 weeks. Builds with Nordstrand or DiMarzio pickups take about 14 weeks.
Deposit:
Reserve your build slot with a 25% deposit of your build price, or pay in full. The remaining balance is due before your bass ships.
Cancellations: Your deposit is fully refundable until we confirm your specs and begin your build. Once your build begins, it’s made just for you and is non-refundable.
Included: Every custom bass ships in a McGrath x Protec hybrid case.
