Introduction The 30th Anniversary Amplifier is the most comprehensive valve amp ever built by Marshall. It’s three separate channels each drive directly into the power amplifier, the same way as in early Marshalls, to provide the maximum amount of natural warmth from the valve powered core. - Page 3 Channel 2 Crunch Crunch is an understatement when describing Channel 2.

Page 5: Rear Panel Features
Rear Panel Features The rear panel of the Anniversary amplifier is the most comprehensive that we have ever produced. In addition to the connection and control facilities there are a number of major innovations that directly affect the sound and performance of the amplifier. As your sound is personal to you, it is important to try the different options for the most suitable settings for your style. - Page 6 43. Series/Parallel Selection Switch Selects series or parallel effects loop operation. Series connection is most suitable for Graphic Equalizers, compressor limiters etc. Parallel connection suits delay, reverb and chorus effects. It is generally not advisable to link distortion effects through the loop. Operational Note F: Effects Loop The main effects loop on this amplifier can be configured either as a series or a parallel loop by using the series/parallel selection switch (item 43).

The Marshall “Failsafe” circuit allows the amplifier to continue running on two valves (providing it is not switched to half power), to get you to the end of the gig.
