Frequently Asked Questions

Below are answers to common questions about custom GLS bass builds, specifications, timelines, and performance expectations.

Do you build multiscale bass guitars?

Yes. GLS multiscale basses are precision-calculated to optimize string tension, low-B clarity, and articulation across the entire fretboard. Each scale configuration is engineered for balance and ergonomic comfort rather than exaggerated fanning for appearance alone.

Do you offer both 4-string and 5-string basses?

Absolutely. We build 4-string and 5-string instruments with scale options ranging from traditional 34” to extended and multiscale configurations. Each build is optimized for your tuning, playing style, and tonal goals.

What electronics options are available?

We offer passive vintage-inspired configurations, active 2-band and 3-band EQ systems, and switchable active/passive setups. Pickup layouts include P, J, P/J, dual humbuckers, and modern soapbar configurations — all wired with noise-managed internal harnesses for studio-grade signal integrity.

Can I customize neck profile and string spacing?

Yes. Neck geometry is tailored to your preference, including profile shape, nut width, string spacing, fret size, and radius. Playability is calibrated to match your technique — whether fingerstyle, slap, pick, or progressive performance.

What is your typical build timeline?

Most custom GLS bass builds are completed within 4–9 months depending on complexity, materials, and electronics configuration. Multiscale and signature-tier builds may require additional time due to precision work and finish curing.

Do you require a deposit?

Yes. A non-refundable design deposit secures your build slot and covers design development and materials allocation. The remaining balance is structured in milestone-based payments throughout the build process.

Can you build a bass for low tunings or extended range clarity?

Absolutely. Extended low-range performance requires careful scale selection, tension balancing, and pickup voicing. We engineer each instrument to maintain clarity and note definition even under aggressive tuning demands.

Are your instruments built for professional touring?

Yes. GLS basses are constructed with stability, hardware reliability, and structural integrity in mind. Each instrument undergoes a documented final inspection and performance certification prior to delivery.

Where are you located?

GLS is based in Camarillo, California (Ventura County), serving Santa Barbara County, Los Angeles County, and clients nationwide. Remote consultations are available for out-of-state customers.
