Custom ’59
Custom ’59 is an amp modeling plug-in that lets you mix and
match preamp tubes and circuits on-the-fly, with complete
automation of all parameters.
Modeled amps
Custom ’59 models three renowned guitar amps: the original
Fender® Bassman®, the Marshall® JTM45® and the
Marshall® JCM800-2203®.
Fender® Bassman®
Originally designed for the Fender Precision Bass®, the
Fender Bassman amp was quickly adopted by guitarists and
eventually became perhaps the most famous and sought after
guitar amp of all time. With its classic 4x10 design (four ten-
inch speakers) and classic lacquered tweed cover, the
Bassman sound is a bona fide icon among guitar tones and a
must-have for any tone aficionado.
Marshall® JTM45®
Introduced in the early 1960’s, the Marshall JTM45 was
essentially a clone of the Fender Bassman. Made popular by
Eric Clapton, the so-called “Bluesbreaker” amp is named
after Clapton’s band at the time, in which he popularized the
now signature sound of playing a Les Paul through the
heavily distorted JTM45. Ever since, the JTM45 has been
ensconced in the pantheon of world-famous guitar
amplifiers.
Marshall® JCM800-2203®
By the early ’80s, Marshall had developed the JCM800, with
higher power tubes and a power boost from 50 to 100 watts.
This amp produces perhaps the most widely recognized
guitar tones of all time.
Create your own amp
Custom ’59™ lets you play an extremely accurate
reproduction of the sound of each of these three famous
amps. But you can also mix and match the preamp tube,
preamp circuit and tone stack from each model to create
your own custom amp.
Input jacks: selects the input channel and impedance.
Channel I and Channel II each have a high-Z input (1) and a
low-Z input (2).
Vol I, Vol II: volume controls for each channel.
3-band EQ: cuts or boosts for low, mid, and high frequencies.
Master: output level.
Preamp Tube: selects a tube for the input stage. This
determines headroom, first-stage gain, distortion character-
istics and to some extent the frequency response of the
volume control circuits.
Preamp Circuit: selects the volume control circuit model for
the indicated amp.
Tone Sta ck : selects the tone control circuit model for the
indicated amp.
