44 Magnum Instructions

Back to Product Page / Instructions (PDF)

Congratulations on your purchase of the 44 MAGNUM guitar amplifier! The 44 MAGNUM produces a powerful 44 watts and is small enough to fit in the palm of your hand. Despite this amp’s small size, at 44 watts the 44 MAGNUM will have no problems being heard at the gig. The 44 MAGNUM’s sweet sound and extreme portability guarantee it to be an integral part of your rig for rehearsal, recording, or playing out. The 44 MAGNUM was designed with the guitar in mind and can be used alone, or with your favorite preamp driving the input to the 44 MAGNUM. The 44 MAGNUM also sounds great with other instruments such as bass and keyboard. Please read this manual to become familiar with the correct use of the 44 MAGNUM.
VOLUME CONTROL — This knob controls the volume or loudness of the amplifier. As you turn the VOLUME knob clockwise, the 44 MAGNUM’s output gets louder. At a certain point in the VOLUME knob’s travel the output will start to overdrive, at this point you are beginning to exceed 44 Watts on your loudest notes. Turning the VOLUME knob further clockwise will produce a more overdriven sound which is the result of pure power amp saturation.

BRIGHT/NORM CONTROL- When engaged, the BRIGHT switch adds a subtle top boost or presence to your signal. When in the NORM position, the top boost is defeated.

INPUT Jack- Plug the output of your guitar, effects pedals or any other instrument into the INPUT jack using a standard ” instrument cable. The input impedance presented at the INPUT jack is 2 Mohm.

8 — 16 ohm OUTPUT Jack — Connect the 44 MAGNUM’s OUTPUT jack directly to a speaker cabinet. 8 ohm - 16 ohm only.


We recommend using a speaker cable between the 44 MAGNUM and speaker cabinet as you would with any power amplifier, though you can get away with using an instrument cable if absolutely necessary. The impedance of the speaker cabinet must be rated between 8 ohm and 16 ohm. 8 ohm is the ideal load for the 44 MAGNUM. Additionally the speaker cabinet must have a power rating equal to or greater than the 44 MAGNUM’s output power capability. We recommend a speaker cabinet with at least a 50W peak rating (or 25W RMS).

WARNING: Make sure the 44 MAGNUM’s output is connected to a speaker cabinet before applying power.
24VDC/3A POWER Jack — Connect the output plug from the 44 MAGNUM’s supplied power supply to the power jack at the top of the unit. Only use the power supply that the 44 MAGNUM was supplied with. The 44 MAGNUM requires a power supply capable of delivering at least 2A (more available current is better) at exactly 24 VDC. DO NOT EXCEED 24 VDC ON THE POWER JACK, doing so will damage the 44 MAGNUM. DO NOT CONNECT AN AC POWER SUPPLY VOLTAGE TO THE 44 MAGNUM, USE DC POWER ONLY. The polarity of the power jack is center positive.
