SOLD - MORGAN AC20 HEAD - £849 delivered

Castro

You'll no doubt surf for reviews and videos - spec is at the bottom so as not to get in your way ;o)

So I'll just say, it is in immaculate condition with the original box and has a £45 cover included. The Twilight covering is bloody gorgeous.

Reason for sale - I have a Morgan RCA35 head, a Swart AST and a Vox AC10 that are covering my needs.

Not looking for amp, effects or acoustic guitar trades. You might tempt me with an electric but I have all I 'need' so it'll need to be something I really 'want'.

Collection can be arranged in Chippenham, Swindon or Hungerford.

The Morgan AC20 is a deceptively simple 20w handwired British AC style amplifier that perfectly captures that classic 60's tone in a small and portable head. Morgan is well known for his simple looking but great sounding amps that are some of the best clean and mid crunch tone makers you can find.

Simple But Powerful

Looking at the front of the amp you may think that it is 'too simple' and won't give you the range of tones that you need. Actually you can do a lot with just the three knobs and two switches on the front panel. The Volume control is of course your volume, but the rest of the amp is a little cryptic. The Cut control is your EQ, it acts as a high cut but in the power section rather than the preamp meaning it responds in a very different way, but while still giving you a lot of range. Match that up with the bright switch and the bass cut switch and you have loads of different options to shape the tone.

Power Control

This is where things get really interesting. While most amps have a master volume control what it does is limit the signal going in to the power amp valves which drastically changes the tone and lower volumes and means that overdrive pedals just don't sound good bellow midday. This amp is drastically different as the Power control doesn't effect how hard the power amp tubes are working and instead limits the output after the power amp stage. This means you can get the same great tone at every volume level without the need of an aftermarket attenuator.

Here's what Morgan say about the AC20 Head

Similar to its big brother, the Morgan AC20 is a deceptively simple, hand wired in the USA, all-tube amplifier that is capable of producing a myriad of early 60s British AC tones - but that is just the beginning. The included power level control allows you to dial in just the right amount of volume without sacrificing your tone the way some master volumes do.

Plugging into the AC20 and you will instantly notice the familiar chime and compression of the Class A EL84 driven output section. Instantly U2, Tom Petty, Queen and most of praise and worship tones will be right there at your fingertips. Like all Morgan amps the AC20 was designed with the pedalboard player in mind. This amp loves all pedals and was designed in a matter where even modulation pedals like reverb and delay sound best in front of the amp. The amplifier's extreme touch-sensitivity will allow you to coax clean tones even at the highest of gain settings. To quote Keith Armstrong (Chief Engineer at Mix LA) "It is impossible to get a bad sound out of this amp!"

The hand crafted in USA head shell is made of void-less Baltic birch ply wrapped in our twilight finish, a proprietary custom ballistic vinyl covering that is vulcanized to the wood to ensure long lasting durability.

The Power Level control is a big part of the magic of the AC-20. Most guitarists today have spent large sums of money and even more amounts of time working on their pedal boards. Most pedals are not designed to be used with a tube amp on "1". They were designed to interact with the 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 that volume can be too loud for most live applications. The Power Level control on the AC20 solves this.

Think of conventional master volumes as a spigot on a garden hose, they choke off the signal to the power section of the amp to a usable level. Most conventional master volumes also affect the way your pedals interact with your amp. The Power Level control behaves like a zoom lens. It limits the size of the output signal that can be produced by the output tubes. It does NOT choke the signal down and therefore behaves identical as if the amp were running at full volume. This means that you can choose the power that you need, anything from 1/4 of a watt to 20 watts.

Morgan does Vox chime really well and the power scaling - effectively a form of attenuation - is absolutely brilliant.
