Feature:
the mg100dfx comes with a two button footswitch, 1.) channel select between, clean, and overdrive channels. 2.) fx on and off. has 1/4 inch jacks for cd/tape player( for playing with your favorite band, or group), headphones out, and guitar input. lead solos can be played on the overdrive channel with customized settings fx include, reverb, chorus, delay, and flange. expermentation with these fx will give out deep lush echos, or jet flanging, my favorite is to play clean lead solos with chorus at different settings. i found the headphones output very useful for practice, this way i can't bother anybody no matter what time it is. i wish the mg100dfx foot control had three or four buttons to shift and change fx by foot thus adding more texture to my solos. all of the other features on the, mg100dfx, are perfect as they are.

Quality:
this amp is built for the working musician as well as the student my son carried it out of the store and he is a very rugged individual he brought it into my home and i could'nt tell if this amp had been handled. yah, the mg100dfx is a pretty tough amp. given reasonable care this amp will last along time what ever along is. this amp is road worthy as long as it's not runned over.

Value:
i would have to say the, mg100dfx, is worth every penny you pay for it.

Desirability:
the traditional marshall tuxedo look, a beautiful amp.

Sound:
before i start i should explain that i once owned the, mg100dfx. i lost my job, so i had to sell the amp back to the store along with other gear i had bought at the same time i bought the mg100dfx. sad i know, but needed to pay my bills. anyway, i am a blues/jazz guitarist, so i experimented with all settings on the mg100dfx and for the price i was amazed of the tone quality no matter what level i had the volume set at. the clean channel gives out a pure pristine tone, while the overdrive channel gives out vintage overdrive, hard rock, heavy metal to a grunge, alternative, and any point in between. even when the onboard fx were applied,in the clean, or the overdrive channel the volume and tone remained unaltered. i then hooked up my, alesis quadraverb gt,fx processer to the, mg100dfx, i had never heard the alesis come so much to life, stereo tones, reverbs, and echos. yep, i tried all the alesis presets through the, mg100dfx, sweet!!! i then hooked up the, behringer fcb1010 midi foot control board to the, alesis quadraverb gt, i experienced true quadraphonics coming from own fingers for the first time not in a studio but in my own home, the, mg100dfx, came to life with rich tones, volumes, and fx. this is unmistakingly a marshall amp, but with a sweet pristine clean tone. my wish is to get this amp back, but i am currently without job, so have to use my income to pay bills until i get another job. this amp is mezmerizing.

Support:
never needed any support the amp was self seffient.

Overall:
keep it . eventually buy other amps one at a time to suit my needs for different types of music.

Feature:
I would have liked a little more flexibility with the DFX but otherwise it is good and they all seem to work quite nicely. I have found one little quirk in the features though... I was tinkering with it for different sounds and I found that if I select the Overdrive channel (does not matter OD1 or OD2 selected) I found that if I turned on the crunch sound on the clean channel it would cause the overdrive channel sound to change. Not sure if this is to be considered a feature or a quirk, also not sure if I like it either. I guess you just have to play with it to see for yourself on that one. : ) I love the line out / headphone jack

Quality:
Built like a tank!

Value:
Lots of amp for the money and that is what I wanted More Amp than bells and whistles.

Desirability:
I spent a long time trying to make a really informed decision about features and what each type of amp in my price range could deliver and this one won hands down. I even brought my own guitar to the music store and stacked the amps in my price range up together and tried them all. I just couldn't allow myself to be swayed by hype.

Sound:
The sound is really great, I am very pleased with it's performance compared to how other amps sounded. I compared it to a wide range from the Spider II to Peavey Classic 30 and Laney amps. I tried it against solid state and tube. I found it produces a good tube sound and works really well at all volume levels which is important to me as I needed the flexibility to play quiet and periodically I play outdoors as well so I needed it to get loud. I also found the clean sounds to be really nice and warm, something other amps had difficulty producing.

Support:
Have not needed it so I reall cannot form an opinion.

Feature:
The Features on this amp Are more then I needed , Its to perfect. the Loop effects , the 2 different distortion channels and everything Its just loads of Awesome Sound! This Amp Has all the necesary features a combo amp needs.

Quality:
Very well made As usual , Marshall Holds up to its reputation with there combo amps. Always Very well made amps. Basically the only way of wreaking this amp is to really mistreat it. Besides all that its got a good finish on it solid enough for those beginer or intermediate shows.

Value:
The Value Is what it is , its perfect !

Desirability:
Put it this way when you Look at the marshall mg 100dfx you start to feel funny. And When you hit the power on it and give it a go Thats a whole different Experience youll have to try for yourself.

Sound:
All I got to Say is This Combo Amp Literally puts any other combo amp out of the competition. The Marshall mg 100 dfx is in a catorgory all alone. This Amp definetly has an awesome killer sound!! The bets Part All together is to Piss your friends of With there marshall 100watt cabs , when you got a marshall mg 100watt that's in a small casing and competes with there large Cab the look on there face is unforgetable.

Support:
I havent had to dealt with the head of the company but Im geussing there not to hard to get a hold of and are nice people.

Overall:
Im always going for a new Amp to get , but the marshall mg 100dfx will remain one of my favorites just because of its diversity and power for its size.
