Hi guys I am an Ampcoholic !!!! well just went yesterday to guitar center to pick up the LM an as soon as saw it something was out the ordinary , I had to put in the power tubes because the store that shipped sent it with the tubes wrap on bubble plastic, so went I was installing it , I notice that one of the tube sockets was just a little loose so I hesitate in turning up the amp or not but the guy a guitar center told me to do it because the amp has to fired no matter what !! so I notice a some noise but very manageable ( must be old tubes), so went ahead and put it in high power select the right impedance , fired up : channel 1 : fucking awesome , all the switches very good it covers a lot of ground , very nice clean channels I ever heard from a Marshall channel 2 : no fucking sound it did not sound at all . what a bump!!! channel 3 : very good : I liked everything it has something very superior that the TSl and JVM no question about it the bite , the tight low end , the fat it has all of it I did not tested the Midi part I have seen a few videos on you tube on repairs and seen some threads and it looks like the circuit on this head its a nightmare !! would you still buy that amp ? guitar center might send it to a tech but the tech that they have its no very good I took a TSl and they just didn't have any Idea of what was going on !! they might sell it for Clearence but i am not sure what to do if buy it cheap and send it to a tech myself or just pass and get another one! the price right now its a $800 but i think they would goo as low for 500 as is !!! any help on this topic would be appreciated !!! Long life to the Marshall forum!!!
