General description
X100M is a "no compromise" guitar head, with all tubes 100W of nominal power. It has
seven 12Ax7 and can be equipped with four final tubes choosing between E34L, 6L6 and
KT66. Preamp section derives directly from X3M and gives thre bas sounds: clean, crunch
and lead.
Clean channel is completely separated from the others and it has gain, treble, mid, bass,
master controls and a bright switch.
Crunch and lead channels share the eq section but they have separate gain and master
controls.
As for X3M, the two passive eq circuits are based on the innovative "total band
suppression" technology, developed by Masotti Guitar Devices for a deep management of
the sound. By this circuit, it's possible to cut completely a band without affecting or
modifying the others. Final stage is identical to Slave100, with same over-dimensioning of
power supply and output transformers, developed and produced in exclusive for MGD.
Final section has Master volume, presence and depth for a total control of amplifier
response. Power supply for heaters is in DC and stabilised for a total elimination of hum,
while particular care has been adopted for HV filtering, in order to give the maximum
dynamics and stability to the sound.
Signal is routed through gold-plated relays.
Channel switching is completely clickless thanks to the microcontroller-based muting
system.
Channel and serial loop selection is made by switches on the front (rear for loop), by a
stomp pedalboard (as our XCF) and via MIDI.
