Yeah,it fits great when there's nothing plugged into it but failing that it's a bit of a tight squeeze!

I guess I'll have to buy a different kind of cover for it so it doesnt get too beaten up with the gigging and everything

The cover is a very tight fit. You don't slip it on, you have to work it on.

Does anyone know if the labels on the footswitch for (Boost, Gate, Reverb, Loop) were written by Yngwie and then copied for the footswitch stickers?

Before I paid $40 or more for a cover I'd buy a light duty 1/4" ply road case on ebay for $150..

Can ya' warm that cover up in the sun or on a dash in the sun then put it on hot and jamb some other stuff in there around the sides..
Ya' know? stretch that sucker out..

I just started using the Yngwie cover on my head. It is tight also, I can get it almost all the way down in front but, not the back. The cables and power cord are in the way. I just hope it doesn't wear out the tolex?

Do they make a case for this head? I thought it was larger than a standard head?

Yeah that is one of my biggest worries. I feel like it would wear out the tolex more by putting the cover on and off than just leaving it off!

I'm hoping I have no issues with this amp. I've never owned a Marshall. I've never owned a tube amp. The YJM100 will be my first!

Well, I just pulled the trigger on a YJM100 today, and should have it by the end of next week. I'm pretty anxious to get it and compare it to my JVM 410H.

I owned a JVM which I sold to get the YJM100. I would pick the YJM100 every second of every day over the JVM. The YJM100 is the prefect amp for blues, 60's, 70's and 80's stuff.

Hey guys, I have a few basic questions about the YJM. First, do you guys know how to autobias new power tubes when they are put in? (Im not replacing them yet but it would be nice to know). Then also the little white turning thing under the EPA is the bias changing right? Another bias question, what does a hotter bias do vs. a colder bias? (in terms of sound). Lastly, is it true that to change a tube in the YJM you have to take out the entire chasis?

Sorry for all the questions guys

Push the effects loop and 50W buttons on the rear while you power on the amp and hold until the valve warning lights begin to flash, now watch the show.
After about a minute or so the warning lights will stop flashing and the 50W button begins to light up.
Once this one stops after another one or two minutes the autio bias is complete.
BTW, no need to turn on the standby switch.

For that trim pot, check the manual for correct settings.
As I understand it a hot bias gives an earlier breakup and more SAG.
Cold bias gives more clean headroom.

You just have to remove the rear cover with 4 screws from the amp to get access to all valves.
