I played one recently and really liked it but - and I know this is going to sound really petty - I can't deal with the Jackson headstock without the truss rod cover it just looks wrong.

Telephant wrote:Billy, we ran into a couple FX loop issues that I want to run by you...

1. Slo has a loop return level. I usually set this to unity, so the amp is same volume whether loop is on or off. For some reason, when using the Jube as master head and SLO as slave (h90 stereo out to SLO return) the SLO was waaaaaay too loud. I had to back off the SLO Return level to almost off! Like barely cracked on. Was really weird. Like the H90 was seeing a crazy hot signal from the Jube and pushing it to the SLO return.

2. However, when just using the Jube in mono, with my H90 in the loop with my custom patches, the delay repeats were way too low and the reverb way too loud, compared to how my same patches sound in the SLO loop. This was confusing as fuck to me considering the above. If the Jube signal was really hot, you'd think both the delay and reverb would be too LOUD. Now this was easily fixed, I simply turned the mix up on the delay and down on the reverb, and then it sounded proper.

I'm guessing both of these issues have to do with the SLO having tube buffered fx loop and the Jube does not? What do you think?

It does everything the Jubilee does but bigger, better, and more of everything

It and the Eventide are made for each other.


And I initially left my Jube behind too. I pulled out of your subdivision thinking that wasn't too hard to pack in the Jeep.. then it clicked that I forgot the damn marshall

Ok so,


1- the way the new SLO loop work is the Send has a -14dB pad to bring the signal from Line Level (+4dB) to instrument level(-10dB). so you can use any guitar pedal through it. Then the Return Level is the recovery stage that brings the signal level back to line level so the power amp can get a proper signal. That means that to get unity gain, the Return Level needs to boost the signal by +10dB, to make up for the padded Send.
Now, if you use the FX Return without using the Send, you are now using getting the full +10db of boost into the power section.
The Jubilee loop is different (assuming we're talking about the original Jubilee, I don't know about teh reissues, although it might be the same). It's also padded, but it's padded to 0dB, like most Marshall loops from the 80's. Which is an Ok compromise for rack effects and most delay/reverb pedals pedals. But it's a -4dB pad vs a -14dB pad, so it will drive the SLO hard.

So you'd have 2 options:

a- lower the output volume of your H90 by -10dB (the main volume not the effects mix).
or
b- lower the Return level of the SLO, which is what you did and it's indeed the easiest way to do it.

So I don't see any issues with this. Just lower the SLO loop level when using as a Slave head. This is normal and the SLO is working as designed.


2- now this one is harder to troubleshoot since I haven't played with the H90 yet, but I am 99% sure this is a configuration issue on the H90 and not an issue with the loops. Are you running your Delay and Reverb in parallel? That could be the issue. Try the 2 effects in series. Also, make sure you have your H90 set for a true analog dry path, so any gain difference would show on the dry path and not on the effects.
Checking these thing is a good starting point. There are probably more things to look at but I haven't had the chance to get my hands on a H90 yet.

Ultimately, if you can't solve it, my suggestion would be to create dedicated patches for uthe SLO alone, the Jubilee alone and the Slave/Master rig, by copying the same patches to 3 different banks and adjusting the levels to fit each situation.

When I use my MS-3 here, I have sets of patches for the DSL, the 2203 and the Mesa, basically the same sounds with adjustments to sound best with each different amp. My experience is that you always have to tweak patches a bit when going from one rig to another, but that's what memory banks are used for.
