BTW if you check the bias be sure you're on full power. Doesn't work in half power mode.
The CR are not a bright amp, it has a dark tone with marshall "ump" maybe a preamp tube are bad.I recently bought this amp, and it's out of the box killing my band members and myself with piercing highs, no matter how much I turn the treble down. I even put a 6 band EQ into my FX board daisy chain and then switched it to being on the fx loop in the back, but that just dulls the overall sound as I turn the high end slightly down. I'm playing both a Tele and a LP using the first channel 1 setting as clean, then it's gain as a mild dirty rhythm. Channel 2 is used for more high gain rhythm and dirty leads. All channels are producing ear piercing high treble. I leave the presence at 5. I don't know how to fix this. Feels like I bought a real lemon of an amp... or is this just what new Marshalls are?
Agreed for a Strat..I'm telling you, turn the Presence OFF. Start there. I was playing mine again last night and when I turned the presence up t to about 9 oclock, it started to get razor thin treble.
I also keep my treble control at about 9 oclock.
Agreed for a LesPaul..The CR are not a bright amp, it has a dark tone with marshall "ump" maybe a preamp tube are bad.
Thanks! Made a difference!.... If not then set the Resonance and Presence to 0 and adjust your EQ the way you like it, then slowly dial in the Presence till your tone is cutting and in your face (Band Level) then slowly dial in the Resonance to get a nice Chug when muting strings. ...
Personally I find that if I play any amp LOUD enough for a few hours I definitely notice less high frequencies.I'd play if some more to get the speakers sorted. Usually with a new speaker it sounds really rough with hardly any lows. It takes a few hours for the harshness to go and bottom end to come in. Eventually the frequencies balance out. Last time I got a combo, I played it an hour or two each day for a weekend and it was already noticeably better.
I also found that the mullard reissue tubes are a bit warmer and fuller sounding, especially the CV4004 compared to the stock ones. I'd see if the speakers improve after a few hours before doing anything.
