Silver-plated, Nylon Core Sub-Bass Strings
for Nylon-String Harp Guitars*

UPDATE 2026

I have contracted with La Bella to supply NEW LOWER-PRICED harp guitar custom gauges with tie ends.
(Ball ends are no longer available)

Material is standard silver-plated copper wire wrap over La Bella's 2001-type balanced formula nylon core.  The stated length is 42", though most range closer to 44" including the loosely wrapped tie end.  Both ends are shown above.  The headstock tuner end is not tapered (it is fully wound to the end), as there is no such thing as a "standard" nylon string harp guitar with specific vibrating or total string lengths to accommodate.  One simply drills out the tuner shaft holes as needed to accept gauges from 0.045" to 0.080".  This decision also save me (and thus, you) some money.

Nylon-core Sub-bass Sets*

* PLEASE READ THE FINE PRINT BELOW BEFORE ORDERING

Harp Guitar Music sub-bass sets are specifically put together by harp guitarist/engineer Gregg Miner for balanced, even tension across all open bass strings to provide optimum tone and feel while retaining a comfortable safety margin for both modern and vintage instruments in either "extra light," "light" or "medium" tensions (see String Scale & Gauge Guide for more).  These handy, pre-gauged sets are offered only through Harp Guitar Music. 

CAUTION: Harp Guitar Music sets are based solely on the measurements of John Doan's original 20-string Sullivan-Elliott harp guitar with sub-bass scale lengths within 5% of those listed in my String Scale & Gauge GuideIf your instrument is much more than 5% different in scale for any sub-bass string, or if you use many different tunings, I highly recommend that you explore custom gauging.  John's own signature set consists of his own gauge choices, and is not a "balanced tension" Harp Guitar Music set.

Harp Guitar Music is not responsible for any instrument damage incurred by stringing.

 John Doan Signature Series Sub-bass Sets

These are the LaBella strings in the gauges that John has been using for decades on his custom Sullivan-Elliott 20-string concert harp guitar.  They were developed from research and consultation between Jeff Elliott and La Bella string consultant/artist endorsee Dennis Cinelli. 

Update: I have long known that this set has very uneven tension across the six sub-basses.  The highest string (D) is very heavy (over 22 lb tension) while the lowest string (F) is extremely light (13 lbs).  I suspect that this was an effort to better match the steel strings that John uses on the neck (the sub adjacent to the neck's low E being the heaviest, and then reducing tension significantly as one goes down the scale).  Obviously, this has worked for John for his entire career, and also many others who string similar instruments with nylon basses.  Note that these instruments are strung by some players with steel basses, and the instruments were actually designed to handle either type, within reason (per Jeffrey Elliott).
