Morgan AC20 Instruction Manual

Amp! Joe Morgan started designing amplifiers to create solutions to the problems he was facing as a guitarist. Joe Designed the AC20 to be reminiscent of the best of the early 60s class A British amplifiers. Don’t let the simple control panel fool you, there is an amazing palate of tones to choose from. The AC20 takes pedals very well and loves Fuzzes, boosts, OD’s, phasers, flangers, tremolos, wahs, and all types of delay pedals. This amp was designed to interface with all of your pedals modern or vintage. • Incredibly versatile single channel amp • ¼ - 20-watt 2X EL84 Power Tubes • 2x 12ax7s • Solid state rectifier • Power level control ¼ - 20W • Cut control • Bass cut switch • Bright switch • Custom transformers and capacitors. • Volume control PLUGGING IN One of the best features of the AC20 is that you can’t get a bad sound out of it. We recommend that you start with the power scaling all of the way up and the volume all of the way down. Cut control set to 12 o’clock and the switches set to the down or “normal” position. From here you can gradually bring up the volume until you reach the desired level of gain. Once you have this set you can change the Power Level control to achieve the level of volume you require. Now that you have your gain and volume set experiment with the bass and treble, and bright switches. Increasing the cut control clockwise will add high frequencies to your signal. We know you will love your new AC20. If you have any questions or help don’t hesitate to email us at [email protected].

reference and for the duration of owning this Morgan Amplifier. Please carefully read and understand the instructions inside this user’s manual before attempting to operate your new amp.

Damage Requiring Service – The amplifier should be serviced by qualified service personnel when: A. The power-supply cord or the plug has been damaged; or B. Objects have fallen, or liquid has been spilled into the amplifier; or C. The amplifier has been exposed to rain; or D. The amplifier does not appear to operate normally or exhibits a marked change in performance; or E. The amplifier has been dropped, or the enclosure damaged. F. The amplifier needs tube replacement or biasing 17. Servicing – The user should not attempt any service to the amplifier beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel. 18. Ventilation – Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the product and to protect it from overheating, and these openings must not be blocked or covered.

same time for optimal tube life. STANDBY SWITCH: Turn ON this switch to put the amp in play mode. This switch should be utilized to put the amp into a wait state for extended periods of rest. It removes high voltage from your tubes. Vol: This controls how much gain you have. As you increase it over about 10 o’clock you will be increasing the amount of overdrive the amp has. Regardless of how high this volume control is, a clean tone is available by simply turning down the volume control on your guitar. Cut : Turning this knob counter clockwise will remove high frequencies from the power section of the amplifier. Think of it as a tone control. Power Level : Turning this knob counter clockwise will decrease the voltage available in the output section of the amplifier. Think of this like a zoom lens for volume. It allows you to go between ¼ a watt and 20 watts. Set your gain level with your Vol control and then lower the Power Level to the volume you require. Bright switch: (sun and moon) This switch in the up position adds high frequencies. Bass and Treble switch: This switch cuts the bass when in the up position. Modes: Bright switch down + bass/treb switch down = Normal Mode Bright switch up + bass/treb switch up = Brilliant Mode INPUT: This is where you plug your guitar cable in.
