I'm new to the forums. I'm the proud owner of a MA100C since Dec 2010 and it seems everytime I look for info on this amp, my search brings me back here. So I finally decided to register. The MA series gets bashed pretty hard in a lot of forums and other places...mostly by people who have only played it for 2 minutes at low volumes. Like me, you all see that this is a damn good Marshall amp and it truly shines when you run it wide open.
I bought mine used and it was manufactured in early 2010, so it's pre-revoicing. I've played it pretty hard, so it's due for a retubing and I've currently got some matched JJ KT77's on the way. I'll be dropping those in and re-biasing this week. I'm expecting the amp to sound even better than it already does once I get those bad boys dialed in. I'm also replacing the pre-amp tubes with JJ 12AX7's.
I've been using a Boss OD-3 in the FX loop as a master volume control and clean boost. I saw a post where someone was using a straight volume pot in the loop as a master volume. I'm actually going to try using a passive volume pedal as a master volume in the FX loop along with an OD-3 clean boost. So essentially SEND => OD-3 => Volume Pedal => RETURN (with some other coloring in there) . I need to get a passive volume pedal first, but I think that setup will give me a lot of options that are purely foot selectable.
Anyway, I absolutely love this amp and am glad I found a place where others see just how damn good it is as well!
Thanks folks.
Rock On!
