NAD: free is free! Marshall Haze

[FuseG4]

A family member of mine got a Marshall Haze 40 back when they came out, thinking they'd learn how to play. They never really got into it. They also said the amp was having issues dropping volume intermittently. I offered to take it off their hands and see if I could fix it, she was happy to let me take the amp and said I could use it as long as I want!

I got it home and couldn't replicate the problems with my gear so basically I just got a free Marshall 40w combo amp, afaik all tube when you bypass the FX DSP and loop,

Amp sounds decent but not great. Really reminds me of the hot rod deluxe, the same kind of range of useable tones and gain and volume but with Marshall flavour. But a little noisey, a little harsh and a little bland and boxy, but still it sounds like a tube Marshall and plays like one.
The bass control useable range however is zero to maybe 3/10. For whatever reason they designed a lot of bass into both channels, and I'm willing to bet that a lot of people who say the amp is muddy just didn't turn the bass down far enough.

But anyways I really like that it was free, it's in brand new condition, and it's got Marshall tone when you dig for it.

I don't think the speaker has even been broken in yet

It's not bad looking from the front

Nothing beats a free Marshall. Nice!

That amp can get some pretty good blues/rock tones when pushed by an OD pedal. But it requires a different EQ than most.

There was a 150K resistor then a 220pf cap to ground right before the drive channel master volume.
That's gives a -3db rolloff point 4.8KHz, muddying the overdrive channel and killing all sparkle, perhaps the designer wanted it to sound warm on guitar center floors. It does, but that's not what I'm after.

Lifting a leg of the 220pf opened up the drive channel considerably. Much more of the presence and bite.

Fun facts, the Haze basically uses the normal channel of a plexi as the normal channel, the boost "off" appears to just put a big resistor in the signal path and change some minor tone shaping stuff.
The OD channel is more interesting, the boost off is like jumping two plexi normal channels. Boost on uses a transistor to switch v1b to a cold biased asymmetrical clipper like in the JCM800, except the stage before in JCM 800 is the plexi LEAD channel.
It has the power amp of a JCM800 with more negative feedback, not sure about supply voltages, but with the .1uf coupling caps like a bassman.

Anyways the amp sounds interesting, the overdrive volume cap removed really worked well, but I still get the name haze, it's as if you were searching for plexi and jcm800 tones but you must wade through thick, choking haze to find it

That's interesting

Hell yeah sign me up for a free amp!

Man this amp really has the Marshall flavor! The c73 mod helps the bass balance with the highs much better and so you can raise the bass control above 3.
It still gets compressed easily and doesn't have as much headroom or punch as my fender, so surprisingly for a lot of stuff my super sonic sounds more aggressive!

When it's daylight again I'll try lowering the gain and raising the master on the Marshall for another comparison. I had the Marshall gain on ten, boost off, tmb and presence on about six. Master on about 4.
The fender was on the clean channel, fat switch off, volume 5 and bass and treble on 7.
