Marshall has renovated its MG guitar amp lineup with the new MG4 series. Combining analog tone, digital control, digital effects and Stompware technology, the MG4 series provides additional versatility.

Models in the new MG4 series are the MG10, a two-channel, 10 watt,
6 1/2-inch combo; the MG15, a two-channel, 15 watt, 8-inch combo;
the MG15FX, a four-channeL, 15 watt, 8-inch combo with digital effects;
the MG30FX, a four-channel, 30 watt, 10-inch combo with digital effects; the MG50FX, a four-channel, 50 watt, 12-inch combo with digital effects; the MG101FX, a four-channel, 100 watt, 1- by 12-inch combo with digital effects; the MG102FX, a four-channel, 100 watt, 2- by 12-inch combo with digital effects; and the MG100HFX, a four-channel, 100 watt head with digital effects. In addition, two 4- by 12-inch cabinets are available - the MG4X12 angled cabinet and the MG4X12B straight-style cabinet.

Gain, followed by a three-band EQ (twoband contour control on the MG10), volume and master volume are laid out for quick access.
Push-button channel switching provides for smooth transitions. Combining analog tone circuitry and Marshall's proprietary FDD technology, the solid-state MG4 series achieves an authentic Marshall sound and feel. The combination line out/headphone out features speaker cabinet emulation, providing the user with full Marshall sound when recording or practicing through headphones. A line input allows for playing along with CDs and MP3s.

The MG50FX, MG101FX, MG102FX and MG100HFX feature a switchable effects loop for adding a favorite external effect to the sound. These models also include the Stompware footswitch as standard equipment.
