15 years of research and development in the field of under-saddle systems has culminated 
in Schertler’s LYDIA. This revolutionary air chamber technology built around an ultra 
linear condenser microphone, with solid diaphragm and integrated electronic settings, 
has been specially designed to reproduce the true sound of your instrument. 
Safe and reliable in all kinds of performance situation, it delivers an impressive sound 
with enhanced dynamic.

LYDIA EQ includes a CLASS-A internal preamp, with volume, bass and treble pots, 
installed in the sound hole. One lithium battery is also supplied.

with previous SCHERTLER under-saddle systems, offering a practical “upgrade” option.


 

Rotosound Bronze Bass 44 Acoustic Medium 40 - 100 Long Scale

Beyond the bronze age
Phosphor bronze is an alloy of copper and tin and has become the industry standard for acoustic guitar strings. 
For music string wire, tin alloyed with copper adds an excellent all round sound with depth and warmth without 
loss of clarity – not quite the zing or edginess of brass but with more of an accentuated middle."

A string for everyone
With so many musicians experimenting with unique gauges and drop tunings it is hardly surprising to know that Swing 
Bass Custom Box Singles, first introduced in the ’60s, enjoy more popularity now than ever before.
With such a wide range starting from 0.025" to 0.140" in increments of 0.005" there will be a gauge to suit 
everyone’s custom set."

Great British quality
Manufactured in the UK to precise tolerances and using only the finest materials, you can rely on Rotosound strings 
for consistent tone and performance in every packet.
Every Swing Bass 66 string is manufactured on custom built machines designed and built in the UK by Jason How.

Iconic music strings
This innovation continues Rotosound’s proud legacy of cutting-edge string design that started with our roundwound 
strings in the sixties.Developed in conjunction with some of the world's top artists, Rotosound strings are 
synonymous with timeless tone, longevity and rock history. Started in 1958 by James How, an engineer who made strings 
or his own instruments, Rotosound became known around the world for its superior quality products and famous endorsees 
such as Jimi Hendrix, Pink Floyd, and Queen to name just a few. The Who’s John Entwistle started a long partnership with 
James and helped develop the Swing Bass roundwound strings which have become the industry standard.
Gathering the most prominent artists over the following decades from Jaco Pastorius to The Edge, Oasis to Guthrie 
Govan, Rotosound has been the go-to string for every music generation."

Swing Bass 66 Billy Sheehan Long Scale - Custom Gauge 43-110

These strings, custom gauged by Billy Sheehan, provide the time tested Rotosound Swing 
Bass 66 standard set with two special advantages:
A slightly lighter G provides a more even string to string tension across the neck and 
makes bending easier.
A heavier E string makes for a tighter low end with increased mass for more volume in the 
lower register. The 0.110? gauge also facilitates tuning down to a low ‘D’ without the 
string bottoming out or loss of intonation.

For the players
They really sound great, there’s a real organic feel to them, I’ve been to the factory where 
they’re hand making them… 
 
“It’s such a part of the tone of everything I do!”
 
“I’m a finger player and when my fingers grip the string the edges on the Rotosound’s, because 
they’re hand wound, grip really strongly so I can get a really good snap of power out of each note.”
– Billy Sheehan"
