    Default I got a new amp today.

    Just spent the first half hour with my new Marshall mf350 mode 4.
    Dialing in some tones.
    Here are my first impressions.

    Clean channel is never something I've ever really liked in any amp. This clean channel sparkles with some beauty.. it feels like there's a lot of meat behind it? I'm no clean channel expert for certain, but I like this one.

    Crunch channel- good for old acdc, chord kind of playing, there's a scoop button there and it sounds like 2 different amps with/without the button.

    Amp 2 side
    OD 1 is meaty, and sizzly, has a bit of a strange voicing to the channel, it's useable for death metal and scoopy speedy riffs. It's not my favorite voice.

    OD 2 has 3 tone switches, and quite a subtle difference between them, I like #2 tone setting the best so far. It is a typical Marshall kind of tone, the whole amp is voiced like many other Marshall amps I've heard.

    What I don't like about it: the knobs feel like they would break if I was thrashing around drunk onstage and crashed into it.... my Peaveys would hold up to that....have....held up to that.
    It's physically heavy.
    OD 2 channel is a bit loose, not nearly as tight as the other 3 channels.


    What I love about it.
    Master volume and individual channel volumes.
    Presence and resonance master
    There's a solo volume knob and a footswitch button marked solo that applies a boost to any channel! That's super!
    It's loud as ****!

    I haven't played with the effects loops yet, I'm grabbing a bite to eat and then playing with all my pedals in front and work up some magial metallic tones hopefully.

    Overall I'm pretty pleased so far. I won't share what I paid for it. But I got a great ...dare I say, Super deal on it. It came with original box, paperwork, cables, footswitch. It looks mint.

    Well the eBay dude refunded my money minus shipping. Good on him.

    Looks like I need to get it to the shop now....
    From what I have read about the amp, the 4 power modules are probably shot. (Common failure)

    It made some cool smoke!
    I rocked the hell out of my Peavey tonight ha ha...and almost an entire bottle of Capn

    So you got a free Marshall head (- shipping and repair costs)? That sound like a pretty sweet deal to me if the repair is simple.

    Everything I've read about this amps shortcomings points to the 4 power modules... I'm not an amp tech guru yet... But I took pictures of where the smoke came from if anyone else is.

    Ha ha Thanks! it DID fit there just perfectly. Really happy with it. It's funny I absolutely love Possessed, but I haven't ever learned a single one of their songs... I mostly play Candlemass, Slayer, and Dokken on this axe, tuned half step down

    I'd love to hear what is wrong with it. Is this a common thing on this model?

    Ok. It looks like these are notorious for blowing up. Bad circuit design apparently. They blow up those chips your pointing at in those pics. They run in those pairs and if even just one goes , both need replacing. The chips themselves are not expensive but the repair process is really touchy, as is the amp operation because of the design. It appears if you have it on [ in working state ] , turn it off and change speakers without the power draining right out first , they'll blow up. Also very easy to short the outputs.

    Apart from changing the chips, those big ceramic resistors in front of the modules there will probably need to be replaced.

    I've dug up a couple of trouble shooting/ repair threads. Let me check them out and I'll get back to you.

    If you could get me a good close up pic of that module , it would be appreciated.
