I've had a Rogue tuberider mvt1000ft for 6 years. I bought it used for $100.00   It has been one heck of a great amp that really puts out, and i do mean "PUTS OUT- REAL NICE". About 3 years ago i bought a "Marshall MG 100 HDFX" full stack and it's "MADE IN VIET NAM". The Rogue has it all over the Marshall. It doesn't have the sound effects (it does have overdrive & reverb) built in but i do have sound effect boxes.  The Rogue has one heck of alot more punch, much better sound all the way around. I'm using it thru my two Marshall speaker cabinets and i will continue to use it. I am looking for another Rogue just in case i need a back-up. The Marshall MG 100 HDFX is junk. They have an issue with the power transformer crapping out and they are expensive to have repaired. The transformer + labor cost come close to the price of a new amp.  The speaker cabinets are great for the money. This model of Marshall is only selling because of it's name. It's pure junk. I've been playing for 46 years, yes, 46 years, and i've had alot of amps (which i won't get into here) but this little story is true.
