Hi,
After reading all your post, I will write only 2 my cents.
Today I compared YJM100 with vintage JMP 1971 PTP small box.
Well ... As we all know, plexi must be cranked. 100% true.
EPA or not , attenuator or not. The best sound you get without it.
Plexi is not bedroom amp!. Both amps with the same settings with
Mesa Horizontal 2x12 cab (Vintage 30 and G12C). EQ presence 0, bass 7, middle 7, treble 7, volume 7,5 not jumpered only top left used.
YJM on 50 W mod, EPA off. Only tube distortion.
Aracom attenuator 4 step down. Both amps.
No attenuated YJM was louder than no attenuated JMP.
What about sound?.
IMHO - old JMP was warmer, fuller, woody in tone.
YJM100 was more harsh, brighter, more modern sounding.
but I was surprised as good YJM100 sounds goes full 100 W option.
Very good, better as 50 mode. Fuller, warmer close to JMP.
(but I notice both holes jumped)
I can say with 50 W was a hungry dog but 100 was a screaming lion!.
Maybe this is it. Difference in 50 and 100 W Marshall amp. No experience with
old vintage Super Lead. I agree with another fans, YJM should be live gigs animal.
About EPA. Very helpfull but sound with Aracom is more my cup of tea.
By the way all the best to members.
PS. Used only CS LP 59 Reissue , Monster cable. Recorded at home by irig recorder.
All comments are welcome.
Please about sound not playing.
PS. Since 1985 no player. No time.....
But started again!!!
