100% AMP TONE

About 5 years ago, Wu came up with an idea that can completely get 100% amp tone. It is different from the first generation of N5 family, It is a totally new design thinking, and Wu established a new circuit platform for it. After years of experimentation and verification, in the summer of 2022, this ultimate mission

100% amp tone has been finally achieved.Yes, you read that correctly, 100% amp tone! The MGAT-1 is just placed in a housing of pedal, in fact, its circuit is the same with amp's preamp circuit. It is exactly the same as the real tube amp in terms of frequency response, dynamics and touch sensitivity, even the EQ shimmer is also the same. Meanwhile, the EQ circuit is more complicated than amps to suit for a variety of applications.

DESIGN THINKING

In order to get 100% amp tone, Wu creacted a new design thought, it is based on the same power amp and cab platform. Firstly, designing
a preamp and let it go into the amp’s FX loop return or IN port of power amp, then repeated comparison and modification with the tone of amp’s preamp, to make the preamp has the exact same tone as the preamp of amp. Once this goal is achieved, the first step is achieved - 100% amp tone. Next, designing a complex clean channel filter, and make it can select the brightness of clean channel, at this point the second step is achieved - applying 100% amp tone to various clean channels.

HYPER PREAMP

Wu defines the preamp that can be connected to both power amp and clean channel as hyper preamp. The hyper preamp is different from the traditional ones, due to equipped with the unique clean channel filter, the hyper preamp can be connected not only to the power amp but also
to the clean channel like a normal pedal, and when connecting it to clean channel, can get the same 100% amp tone as connecting it to the power amp.

MGAT-1 PLATFORM - The new generation of N5 family is based on Multistage Gain Generator & Advanced Tone-shaping system platform 1, MGAT- 1.

MGAT-1 has the most powerful gain generator circuit. Firstly, three completely different channels are formed by increasing or decreasing the number of gain stages, CLEAN & CRUNCH channel, OD1 channel and OD2 channel. These three channels have different numbers of gain stages, and getting different amounts of gain. The CLEAN & CRUNCH channel is designed according to JTM45, it can get classic early British clean and crunch tone; The OD1 channel is the OD tone of hard rock from the late 60s to the 80s, covering JCM800 and PLEXI; The OD2 is the high-gain tone of modern Marshall, from high-gain to ultra-gain.

Meanwhile, the OD1 and OD2 channels have a shared 3-levels selectable gain structure and an independent 3-levels selectable gain saturation. About Gain Structure, it means to adjust the structure of the gain stage to get different gain feel. About Gain Saturation, it means to adjust the amplification amount of the gain stage to get the different feel of gain tone. So, in gain generator part, MGAT-1 can provide 19 different gain tone, covering from clean to ultra-gain, also gain tones of various amplification styles.

MGAT-1 has the most advanced tone shaping system circuit. The tone shaping system can accurately capture the frequency response of the tube amp, so that the response of the tone as the volume changes is completely consistent with the tube amp, when playing in different positions of volume knob on the guitar, you can't tell which is the tube amp and which is the MGAT-1. Even the shimmer generated by tube amp’s tone stack, MGAT-1 also can accurately generate.

MGAT-1 has a clean channel filter, this is the biggest difference between MGAT-1 and other preamps. Once the signal passes through this clean channel filter, it can be used in any clean channel of various brightness. If turning off clean channel filter, MGAT-1 will be connected to power amp or other devices like other normal preamps. The EQ part of MGAT-1 is very powerful. It is not only reflected in frequency response, the adjustment of frequency points is also perfect. Moreover, the EQ adjustment range is much wider than that of tube amp, the advantage of this is that the MGAT-1 is able to have more adjustment margin to get better tone when using in the clean channel, or if it is used as a preamp, there are richer tone adjustments than traditional amps.

FIVE CLASSIC MARSHALL MODELS

MGAT-1 is based on five classic marshall models, and though years of comparative analysis and experiments. MGAT -1 covers from Marshall vintage clean in 1962 to the iconic Marshall crunch in the 70s & 80s, and also later modern high-gain, so to speak, MGAT-1 is a book about the history of Marshall, all kinds of legendaryMarshall tone can be obtained by adjusting MGAT-1.The green channel of MGAT- 1 is compared with the JTM45’s bright channel; The orange channel is compared and modified from 1987X bright channel, SLP59 bright channel and JCM800 HI Input; The red channel is compared with the orange status and red status of JVM410H’s OD1 channel and OD2 channel. These comparative experiments have been repeated thousands of times, modified and corrected. Wu can tell you responsibly that the tone similarity with Marshall amps reach 95%, you can get these tones according to the parameters of some models.

Main Differences in GOLDEN ERA Version Compared to the Original MAGT-1

TONE difference - the MGAT-1 Golden Era has a clearer tone, huge low frequencies, and more power, making it infinitely closer to the true tone of a Marshall amp compared to the original MGAT-1.

GAIN difference - The gain of the green channel of MGAT-1 Golden Era is greater than that of the original MGAT-1, while the gain of the orange and red channels is slightly less than that of the original MGAT-1. However, like the original Mgat-1, the
MGAT-1 Golden Era can also achieve an ultra-high gain level.

SWITCH difference - The MGAT-1 Golden Era uses the GOLD ERA switch to replace the MID-RANGE switch of the original MGAT-1. The circuit principles of these two switches are completely different. The GOLD ERA switch is the most distinctive among all the switches and is one of the core secrets of its tone. It can quickly find the tonal balance between Plexi and JCM800, accurately producing the sounds of either Plexi or JCM800. This switch is also the biggest difference between the MGAT-1 Golden Era and the original MGAT-1
