Should I Drop Tank Bigsby?

When It Makes Sense

• Good fit: You play a heavy, low‑tuned guitar where the added mass of a Bigsby improves sustain and you need the lower center of gravity a drop‑tank provides for comfortable standing performances.
• Good fit: You are customizing a vintage‑style instrument for a specific studio sound and have the technical skill to modify the body without compromising structural integrity.

When You Should Avoid It

• Warning sign: Your guitar is still under manufacturer warranty and any structural alteration could void that coverage.
• Warning sign: You lack the tools or experience for precise routing and soldering, increasing the risk of damage to the instrument’s electronics or body.

Pros and Cons

Pros

• The combined drop‑tank and Bigsby can lower the instrument’s center of gravity, making it easier to play for long periods.
• A Bigsby adds subtle vibrato capabilities that many players find musically expressive, especially in blues and rock genres.

Cons

• Modifying the tank adds weight, which may affect balance and can cause fatigue during extended sessions.
• The installation process is irreversible for most guitars and could reduce resale value if not performed flawlessly.

Decision Checklist

• Do I have the necessary tools, space, and technical know‑how to perform a clean modification?
• Will the tonal and ergonomic benefits outweigh the added weight and potential warranty loss?
• Have I consulted a qualified guitar technician or luthier to assess feasibility for my specific model?

Alternatives to Consider

If you want vibrato without a full drop‑tank conversion, consider adding a lightweight vibrato bridge (e.g., a tremolo tailpiece) or using a pedal for pitch modulation. Another option is a smaller, removable Bigsby kit designed for easy installation without permanent body routing.

Final Recommendation

Dropping a tank to install a Bigsby makes sense for players who prioritize sustain, vibrato depth, and a lowered center of gravity, and who have the skill or professional help to execute the modification safely. If warranty, weight, or resale concerns are high priorities, explore non‑permanent vibrato solutions first. Always seek advice from a qualified guitar technician before undertaking structural changes, especially when the decision involves high‑value or vintage instruments.
