I got my amp today and I like it very much.

I ordered one yesterday without really knowing what it sounds like exept for some youtube clips. Reading your review makes me think it's gonna be great. I did the same thing with the AFD and the YJM and must say I'm really happy with those amps so looking forward to play the 2555 X. I just wanted to...

Well, just wanted to say, it's 1 year to the day since I got my YJM and
I'm still very happy every time I turn it on.
( I'm also happy when it's not turned on
just because I have it.)

It's the new sig for Bill Kelliher of Mastodon.
He's mostly playing the bridge pickup so I think that's the reason
for the strange location of the selector switch.

I agree with Mat_P, something is wrong. I don't have a volume drop when turning on the fx loop. I run a MXR Boost/ line driver in the loop to get more volume for solos and stuff like that + a TC electronics flashback.

They are built like tanks! I got one the year they came out and it's still fine.

I love this amp!

Spot on Marshall Fiend, the Peavey head is stamped with the year 1978.
The cab isn't much fun to move around, it weighs a ton!

Great choice Surf! Everybody needs a new YJM if you ask me

Me too!

The prettiest isn't always the best!

I had the same problem some years ago. Got the T-Rex Fuel Tank Junior
and the problem was solved.

My amp sounds great with the standard 1960 cab and EPA on 50% or more,
with or without booster, so yes, something must be wrong.

Here is our current live rig, loud as hell!

It sure does
