The Controls: (Continued)

TREBLE : (Continued) The one place you may want to throw caution to the wind and set the TREBLE Control above this median zone presents itself in Channel 1. In both modes ( Clean & Pushed ) the TREBLE Control can be used to dump extra gain into the mix. This is especially effective in the PUSHED mode for crunch sounds. When doing so use the PRESENCE Control to roll off some of the more than ample top end for a more compressed feel and fatter voice. As you might surmise, the BASS Controls’ effectiveness will be reduced, so you may have to run a much higher setting than you are used to seeing to achieve a balance.

MID : The MIDDLE Control is responsible for the blend of midrange frequencies in the mix and though its effect is not as dramatic as that of the TREBLE Control, it plays an integral part in achieving any sound in your Nomad. It is capable of changing the feel dramatically

 

 

 

as it blends in a group of frequencies that tend to soften or stiffen the way a

Most players tend to lean in the direction of lower MIDDLE Control settings (

the MIDDLE Control is increased, ( 11:30 - 1:30 ) the sound is rounded-out and

times when a specific deficiency is produced by either an extremely high setting

of other tone controls, or a physical anomaly in the room. While these MIDDLE Control settings ( 2:00 - 5:00 ) can introduce added gain and create enhanced focus, the trade-off will be a stiffer, more forward, less compressed feel.

Channel 1 utilizes a different MIDDLE Control than that of the Channels 2 and 3 with a custom-designed taper and value. In its low range ( below 12:00 ) it functions as a normal midrange control with a taper suited to blending fine increments of these frequencies. Most players lean toward a fairly radical scoop ( 7:00 - 10:30 ) for clean playing, preferring to let Treble and Bass remain dominant, thus producing the signature sparkle and breath essential for a pristine clean sound.

As Channel 1’s MIDDLE Control is swept past 1:00, it quickly starts to add gain in these midrange frequencies adding cut and punch. As the top end of the control is reached, ( 3:00 - 5:00 ) it becomes an additional gain control capable of taking both CLEAN and PUSHED modes to extremes. Experiment with this cranked region in conjunction with extreme settings of the other tone controls to balance both sound and feel. While this added flexibility may make Channel 1’s MIDDLE Control a little more tricky to learn at first, it will become quite valuable as you start to realize the power of this super versatile channel.

BASS : Last, but definitely not least in the string of tone controls we, come to the BASS Control. This control works similarly in all three channels in that it determines the amount of low frequencies present in a sound. However, the actual frequencies and style of lows it mixes in changes from channel to channel. Like the MIDDLE Control, it falls in line signal-wise after the TREBLE Control and the same scheme

 

applies. When the TREBLE Control is set high the effectiveness of

the BASS and MIDDLE Controls is reduced. If the TREBLE Con-

For the most balanced sound and a balance of power between the

nuetral starting point for further tweaking.

45, 55, 100 specifications

Mesa/Boogie, a name synonymous with innovation in the guitar amplification world, has carved out a niche in the hearts of musicians with its formidable lineup of amplifiers. Among these, the Mark series stands out, particularly with models like the Mark 100, 55, and 45. Each model brings its unique flavor and versatility, allowing players to craft their sound with precision.

The Mesa/Boogie Mark 100 is a powerhouse in the 100-watt category. It boasts multiple channels, allowing guitarists to switch between clean, crunchy, and high-gain tones effortlessly. One of its standout features is the onboard EQ, which facilitates fine-tuning for different guitars, pickups, and musical styles. The Mark 100 is engineered with Mesa's signature Dyna-Watt technology, providing a dynamic response at various volume levels without sacrificing tonal quality. This responsiveness makes it ideal for both live performance and studio recording, as it yields rich harmonic overtones and a wide dynamic range.

Moving to the Mark 55, this model offers a refined approach with 55 watts of power. It retains many features present in the Mark 100 but is more accessible for players who prefer a slightly lower wattage. The Mark 55 excels in mid-gain settings and is popular among blues and rock guitarists. Its Dual Rectifier circuitry can dial in everything from smooth, bluesy overdrive to tight, aggressive rock tones. The amp also incorporates a versatile effects loop, providing seamless integration with pedals and processors, making it a favorite among pedal enthusiasts.

The Mark 45, perhaps the most compact of the trio, brings 45 watts of power to the table, making it a versatile choice for players seeking portability without compromising tone. It retains critical features such as multiple channels and a powerful EQ section while being lighter and easier to transport. The Mark 45's sweet spot is found in its ability to deliver rich, saturated tones at manageable volume levels. Often favored for intimate gigs and home recordings, its versatility allows players to explore genres from jazz to metal with equal flair.

All three Mesa/Boogie amplifiers utilize high-quality components designed for durability and peak performance. Their construction is robust, ensuring reliability on stage or in the studio. With advanced features such as power scaling and tube rectification options, musicians can tailor their sound precisely.

In summary, the Mesa/Boogie Mark 100, 55, and 45 each present guitarists with distinctive tonal characteristics and features that enhance playability and sound. From the powerful performance of the 100 to the compact yet versatile 45, these amplifiers deliver the high-quality, rich tones that Mesa/Boogie is renowned for, catering to the diverse needs of players across genres.
