Dual 20 Head



Two Separate Channels

The Morgan DUAL 20 combines the original “AC 20 Deluxe” and “Abbey” into one package. Two separate channels, each recreate all the features of the originals. Use any A/B/Y footswitch to change between, or even combine, channels.

The DUAL 20s NORMAL channel has a switchable EF86 tube, voicing the range of tones from the cleanest of EL84 chime to ferocious high gain growl. A Bass Cut and a Bright switch allow you to completely sculpt your tone. The DUAL 20s TOP BOOST channel adds bass and treble controls as well as an extra stage of gain. This channel is perfect for capturing Tom Petty and Beatles tones. The DUAL 20 uses a global CUT control to smooth the top end in the power section of the amp, allowing you to dial in just the right amount of chime.


Power Level control

The DUAL 20 features Morgan’s revolutionary Power Level control which is a big part of the magic of this amplifier.  Many guitarists today have spent large sums of time and money working on their pedal boards.  Most pedals are not designed to be used with a tube amp on “1”, but rather to, interact with an amplifier at, or near, the point at which it begins to break up. That is why an overdrive pedal is called an “over” drive.  It is driving the amp over that point.  Unfortunately, this can make the volume too loud for most live applications. The Power Level control on the DUAL 20 solves this issue. Think of conventional master volumes as a spigot on a garden hose. They choke signal off to the power section of the amp to attain a usable level. Most conventional master volumes also affect the way your pedals interact with your amp. Morgan’s Power Level control behaves like a zoom lens, limiting the size of the output signal that can be produced by the output tubes.  It does NOT choke the signal down, and therefore, the amp behaves identically to running at full volume. This means that you can choose the power that you need from a ¼ of a watt to 20 watts.

Morgan History

Joe Morgan has been building, modifying and repairing amplifiers since 1996. His designs are seen in stadiums and arenas all over the world. It is hard to turn on a music awards show without seeing his products. Joe designs for the working musician, whether that means a Sunday morning church gig or touring the world with James Taylor.

Joe will be the first to tell you that tube amps are not rocket science (Joe was part of the engineering team that developed the first GPS satellites). Tube amps are only as good as their components and Morgan chooses the best of the best. Engineered with custom designed transformers to provide the best possible sonic signature they also provide Morgan with the confidence to offer a limited lifetime warranty.

Handwired in the USA.
