14 Feb Playing with a Marshall YJM (quick initial impressions)

Marshall YJM poster.

So, just got a used (but like new) Marshall YJM, which is a signature amp (Yngwie Malmsteen). While I never cared for Mr. Malmsteen not even for two seconds in a row (with Respect), I love the amp.

It is basically a regular Marshall 1959 Super Lead, 100 watts amplifier (which is my favourite amplifier type in the world), loaded with additional features that the vintage ones don’t have. Including a boost, reverb, noise gate and embedded attenuation via a modern “EPA” electronic circuit that lowers the voltage going to the main (EL34) tubes thus reducing the output up to bedroom levels.

I immediately tried the EPA function, which didn’t strike me as the best attenuation method available – it lets the amp drive way less and subtracts high frequencies, at least compared to my Aracom.

Expect a much better review of this soon – I am very interested in the differences between new and vintage amps, attenuation technologies and tone in general (you knew it didn’t you). I think these right here are all the necessary tools for us bedroom rockers, and I will not stop investigating.

Edit: after speaking with friend CrossroadsNYC (moderator at the marshallforum.com) it turns out that these are known characteristics, and it is just normal for the EPA to behave like that. I still like my Aracom a number of times better, however keeping in mind that the Aracom is a few more hundred bucks and the EPA is included with the amp… you know the math.

 

I made this little AC/DC copycat thing this morning to let you have a grasp of what the YJM sounds like. All parts played with a 1967 Gibson SG Standard (the one that was recently repainted), stock pickup (which I don’t even know if it is a t-top anymore, it came with the guitar and it is rather old). Cabinet is a Marshall B type with vintage 1970s G12Ms “blackbacks”. Microphone was  my newly acquired Neumann U47 FET (god I love it).

The two guitars on the sides were played with NO TSR; the solo in the centre was played with TSR in standby for its first half, then TSR on (you should be able to tell when this happens).

The Marshall YJM settings were P0, M4, T6, V4 (yep, voume on 4), attenuated with my Aracom. Guitar volume and tone both on 10.

Like it?


Wanted to add the backing track in case someone wants it
