This is a Marshall MG30FX. It's a 30W combo amplifier from Marshall's entry-level "MG Gold" series. The body has some scratches, but overall, it's in good condition. The sound is fine for all tones, with no crackling or noise. 1. Sound and Basic Specs It reproduces the traditional Marshall sound, and with 30W of output and a 10-inch speaker, it has a richer bass and thicker sound than home amplifiers (usually 10-15W). 4 channels: Clean / Crunch / OD1 / OD2 Covers a wide range of sounds, from transparent cleans to JCM800-like crunch and modern high-gain. 3-band EQ: Bass / Middle / Treble for detailed sound shaping. 2. Comprehensive Digital Effects You can enjoy a variety of tones with just this one unit, without having to buy additional effects pedals. Spatial effects: Chorus, Phaser, Flanger, Delay, Octave. Reverb: Has an independent knob and can be used simultaneously with spatial effects. Tap Tempo: A convenient function that allows you to set the delay time by tapping the switch. 3. Convenient Features (Perfect for practicing at home) Headphone jack: The sound with a speaker simulator comes out, so you can practice with powerful sound even at night. External input (AUX IN): Connect your smartphone or music player and play along with your favorite songs. Memory function: You can save the settings for each channel, so you can recall your favorite settings with a single switch. This is a step-up amplifier that can handle everything from home practice to small gigs! Thank you.
