MesaBoogie EX412 Introduction

Mesa/Boogie is an amplifier brand founded in California, USA in 1969. Randall Smith, the founder and designer of his company’s products, had humble beginnings repairing and modifying Fender amps in a local repair shop. His work there laid the foundation for creating the Mesa/Boogie brand. Originally just repairing amplifiers, the company expanded into making sturdy amplifiers that are durable and hard to break down. They are known for having a unique hammer test, in which a completed amp is hit many times with a hammer to test its durability. The test earned such a reputation that the company’s products have earned the tremendous trust of top musicians on world tours.

The Mark series, famous as a multi-channel amp that can produce multiple tones, changed the fundamental concept of single-channel amps at the time. The development of this series finally brought the company worldwide recognition. The Mark series has undergone model changes from Mark1 to Mark5, and has been favored by many guitarists. The fat and sweet sound of the Mark series can be heard in many historical works considered masterpieces.

The Rectifier amplifier, with its high gain sound that adapted to the changing music scene, was the originator of modern high gain amplifiers and became a masterpiece amp head in Mesa/Boogie’s history, and also influenced other amp brands.Until then, 100-watt high power amplifiers used a rectifying circuit using a silicon diode, but by adopting the Rectifying Tube used in vintage amplifiers, the Rectifier succeeded in achieving both a high-gain sound and a sound that makes you feel plump and warm. The Rectifier amplifier is still popular today, and can be seen on many stages.

Mesa/Boogie has continued to create dedicated cabinets to express the sound of their amp heads. These cabinets are also works of great craftsmanship..Even if using an amp head from another company, Mesa/Boogie cabinets are a favorite for recording and stage use. Simple proof of how good and reliable the company’s cabinets are. It has many excellent recording characteristics that do not need a particular amplifier, and many recording studios have permanent Mesa/Boogie cabinets.

The EX412 Cabinet uses an “iron grate” as the front grille instead of the saran net grille used in general cabinets for thick enclosures.It is worth noting that the EX412 is a traditional slant layout of 4-shot cabinets, but has a unique half-open style with the back of the top 2 shots open back and the bottom closed back. This gives the bottom sound a sense of heaviness and sound pressure that many guitarists will feel most important in high gain sound. They succeeded in adding a high-frequency spread like a combo amplifier. In addition, you can mix two types of open and closed structures with one cabinet. By recording two sounds, you can mix them and blend the sound with the open back spread to the tight sound of the closed back, or switch between the closed back for drive sound and the open back for clean sound. You can also make a wide range of sound makeup.

The speaker units installed in the EX412 are Mesa/Boogie’s traditional BlackShadow on the upper row, and Celetion’s Vintage 30, the most famous and well-established speaker unit for guitar amps, on the lower row. The punchy and sharp sound of the high range is attractive to hear.


What is unique about Mesa/Boogie is that the British brand Marshall uses 16 ohms for the total ohms of the cabinet, whereas Mesa/Boogie traditionally uses 8 ohms.There are various theories about this, but DYNAX’s view is that even with the same Vintage 30 speaker unit, the sound tends to change between 8 ohm and 16 ohm during recording and IR creation.

The combination of Mesa/Boogie’s traditional high-quality birch wood, hand-crafted woodcraft by skilled artisans, and heavy-duty hardware makes their products robust enough to withstand the world tour stages.
