2 PCS 6mm & 5mm Whammy Bar for Electric Guitar — Tweruna
Included as a complete set, this Tremolo Arm pair offers both a black M5 bar and a white M6 bar. Made from stainless steel, these arms aim for durability and long life. The dual-size design makes it easier to match different Strat-style tremolo systems and other models. Best for players who want quick compatibility without carrying multiple single bars. A limitation is that color and finish options are fixed to the two provided bars, which may not match all guitar finishes perfectly.
2Pcs 6mm & 5mm Thread Tremolo Arm — Hariendny
This set provides both 5mm and 6mm tremolo arms in a compact package. Built from metal, it emphasizes durability for long-term use and aims to improve string tension control for a more pronounced tremolo effect. Best for players who want a budget-friendly two-size option in one purchase. Potential drawback: the finish and threading precision may vary between batches, so some mounting adjustments could be needed.

Its length and threading are tuned for standard 6 mm interfaces, providing reliable attachment and stable vibrato performance. Best for players seeking a straightforward, durable upgrade for a classic tremolo setup. Limitation: only one size is provided, so it may not fit non-6 mm threads without adapters.

The material is a high-quality metal alloy with corrosion resistance. Best for players who want a versatile, single-arm solution adaptable to multiple guitars.

Buying Guide
What to consider when choosing a whammy bar:
- Thread size compatibility: Verify 5 mm or 6 mm threads to match your guitar’s tremolo bridge.
- Material and durability: Metal alloys and stainless steel offer longevity; zinc alloy provides ruggedness with cost considerations.
- Two-size sets vs single bars: Two-size packs simplify matching multiple guitars or spare setups.
- Grip and comfort: ABS caps and bar diameter influence grip during expressive playing.
- Finish and color: Some players prefer bars that visually blend with their guitar; consider finishes accordingly.
- Installation ease: Threads should screw securely without cross-threading; ensure compatibility with your tremolo system.
Frequently Asked Questions
- What is a tremolo arm’s main purpose?
It allows string tension changes to produce vibrato, pitch bends, and dive bombs for expressive playing. - How do I know which thread size I need?
Check your guitar’s tremolo bridge specification or measure the existing arm’s thread diameter (5 mm or 6 mm). - Are two-arm sets better than single arms?
Yes for players with multiple guitars or for quick replacements without shopping again. - Can I mix arms from different brands?
Yes, as long as thread sizes match, but balance and weight can affect feel. - Will replacing the tremolo arm affect intonation?
- Is a heavier arm better for stability?
The arm itself typically does not affect intonation; it mainly affects vibrato feel and string tension during use. Fine-tuning may be unnecessary unless mechanical fit changes occur.
A heavier arm can feel more stable and provide smoother tension control, but comfort and playing style vary by musician.
