CLASSIC
LEAD 80
The Classic Lead is a fine example of the
sonic characteristics of a loudspeaker
evolving as new materials become
available.
Revolutionary in the late ’70s, a fibreglass
voice coil former - capable of withstanding
very high temperatures - was used to give the
Classic Lead a muscular 80W power handling.
This also increased barrel stiffness, affecting
the way the cone vibrated and influencing
cone break up. Then, through experimentation
with edge treatments and continued critical
listening, some modes were encouraged while
others were suppressed, contributing to the
speaker’s unique sound.
Today, the Classic Lead is much-loved by lead
guitarists for its speed, punch and articulation,
with every note clearly defined on even big,
distorted sounds.
The Classic Lead also sounds great clean, with
that same articulation combining with high
headroom to deliver a fluid, dynamic
performance.
