Okay, next up the JCM 800 with and without the attenuator. I waffle back and forth between the 800 and the 100w Plexi being my own personal favorites, but this one usually gets the nod. As far as I'm concerned, this amp rules them all. This amp has the perfect tone for what I like to do.
Gibson Angus SG again - bridge pickup
Marshall JCM 800 2203
Presence - 6
Bass - 6
Mid - 5
Treb - 7
Preamp vol - 7
Marshall 1960b 4x12 - Vintage 30 - Senn e609 dustcap/cone - Audix i5 edge - equal blend
Both mics on axis, on grill
No EQ
First up, the "baseline". Master vol on 8, no attenuator. Unbelievably loud. Way too loud for a bar/club gig. Good for recording if your neighbors can stand it. In my own personal opinion, for my own wants and needs, rock and roll guitar tone doesn't get much better than this.
JCM 800 master vol 8
Now we'll turn it down to "gig friendly" levels with the master volume and attenuator. The attenuated clip has the amp at baseline vol setting (8), and turned down only with the attenuator.
JCM 800 gig volume - master vol 5
JCM 800 gig volume w/ attenuator
Now for jonnydeep, this is at what he called "moderate recording" level. Not quite gig loud, but still probably too loud for peaceful jamming at home without disturbing others in the house. Much louder than a TV, but not so loud that it hurts you ears too bad. Again, I turned the master volume up to 8 and turned it back down with the attenuator for the attenuator clip. I did use the treble compensation on the attenuator at this point.
JCM 800 master vol 2.5 - moderate recording volume
JCM 800 moderate recording vol w/ attenuator
And now, pretty much useless quiet TV volume clips. This is not an amp for peaceful jamming at low levels. The JVM does this sort of thing way way better. Like the others, the attenuated clip is with the amp turned up to 8, and turned back down only with the attenuator.
JCM 800 master vol 1 - TV volume
JCM 800 TV volume w/ attenuator
A few clips normalized for same relative loudness comparison.
JCM 800 master vol 8 - normalized
JCM 800 master vol 1 TV vol - normalized
JCM 800 TV vol w/ attenuator - normalized
So that's the JCM 800. Next up, it's older but smaller brother the 50w JMP 2204 master volume.
