The Dunlop 938 Stainless Steel Tonebar pairs a versatile 3-9/16" length with a full 1" diameter for steel guitar players who want generous coverage, a substantial grip and strong sustain. The 3-9/16" length works well as an all-around steel guitar size, while the 1" diameter adds mass that can help notes sing longer and gives vibrato a broader, more controlled feel. Made from high-quality stainless steel and polished for smooth action, the 938 glides cleanly across the strings for accurate intonation, sustained chords and expressive pedal steel, lap steel or resonator guitar phrasing. Made in the USA, this tone bar is built for players who want a heavier, confident feel without moving to the longest bar sizes.
