MN™-100 GUitAr AMplifier Congratulations on purchasing this Budda guitar amplifier. After initially creating a reputation for producing boutique tone machines, we have now raised the bar for modern multi-channel tube guitar amplifiers by producing possibly the most sophisticated tube guitar amp available.
  • Page 5: Before Applying Power

    Quick Guide Please at least read this section before using your new amplifier. We then recommend reading the rest of the manual so you can get the most out of this very sophisticated unit. Before applying power: 1) When setting up, ensure that the amplifier speaker output is connected to your speaker enclosure with a good quality speaker cable (do not use a normal shielded instrument cable) and that the Impedance switch on the rear panel is set to the correct setting.
  • Page 6 MN™-100 GUitAr AMplifier 4) Before switching on, set the Master Volume to the minimum setting. The first time the amp is used, we recommend setting all the other controls to their mid setting. 5) Now flip the Power switch to the up (on) position. The power status lamp should be lit. Wait at least one minute for the tubes to warm up.
  • Page 7 Front Panel Functions: What they do and hoW to use them (5) Gain This control sets how much signal is sent through the Channel 1 preamp. Low to medium settings will produce clean sounds. As the control is turned further clockwise the tone will get warmer and eventually start to add a small amount of overdrive.
  • Page 8 MN™-100 GUitAr AMplifier 1 & 2 channel 2 This is the ‘crunch’ channel. Depending on the specific setting of the controls it can produce lightly overdriven tones that clean up nicely when the guitar volume is turned down, through to quite heavily overdriven tones at high Gain settings, especially with the Over-Boost switched on.
  • Page 9 Front Panel Functions: What they do and hoW to use them channel 3 This is the ‘high gain’ channel. Depending on the specific setting of the controls, it can produce warm overdriven tones, seriously heavy thrash tones and anything in-between. (23) channel select Works the same as on Channel 1 but for Channel 3, including switching on Over-Boost.
  • Page 10: Power Switch

    MN™-100 GUitAr AMplifier 1 & 2 master section (33) Boost This sets a user definable volume boost that can be applied to any of the three channels and can be turned on and off using the footcontroller. This is extremely useful when you need a boost in volume for solos, as you don’t have to dedicate a particular channel for that use.

Preferably connections at the footcontroller and the amplifier should be made before the amp is powered up. (80) Preset mode This switches the footcontroller between NORMAL mode (default, LED off) and PRESET mode (LED red).

    You can connect the MIDI Out to the MIDI In of another MN-100 to synchronize the two amps. With the footswitch connected to the first amp, any changes you make with the footswitch (or front panel) will be duplicated on the 2nd amp – if the 2nd amp is on the same MIDI channel.
