Mark VII - dang double gang - messed up FX levels

The coffee shop guy with his acoustic guitar makes it look so easy!

man don't you just hate that... sigh

So a cool way around this is to run the CabClone out into the looper then run the looper into some powered monitors or speakers. I do this because of the volume issues. Some loopers like my RC-5 have a built in drum machine which sounds way better with full range speaker than through a guitar speakers anyway.

Just one more oddity I noticed when playing out last weekend. I had the FX LOOP on pretty much the whole time with a subtle delay. Well, when switching channels from 2 to 3 there was a very loud burst of sound. It ends up that the delay level in Ch 2 was fine but when switching to Ch 3 the delay echo would get overly amplified and be really loud for an echo or two.

Just another artifact of the drastic FX LOOP level differences between the channels.

Too early of a release on the strobe mute circuit? They slow the response on the reverb circuit to get rid of the transient noise from altering the circuit path with the relays. Think they need something similar on the FX loop?

what about the addition of an outboard fx unit that has volume control per preset?

I have a Mark V 90W and the power amp changes volume with just about every setting. On ch3, extreme is much louder than mk4 and mk2, I have to engage the solo boost to get them as loud as extreme was without changing the channel volume.
Switching from EQ sliders to preset EQ makes a huge volume increase.
I'm also running stereo with another 4x6L6 power amp set to 50W. If I'm on channel 3, 45W, and have the two stereo channels' volume equal, if I switch to ch2, 45W, the stereo volume becomes unbalanced, one side is louder than the other.
If I run a preamp distortion pedal (i.e. Fortin Natas) straight into the FX return of Mark V, with ch2+3 both on 45W, one is louder than the other (even though the preamp channels aren't making it to the power amp). Also, the power amp volume still gets louder on extreme vs mk4 or mk2, even when bypassing the preamp with a pedal straight into the FX return.

That isn't abnormal for that amp. The extreme mode reduces negative feedback to the power amp so it will cause a volume jump compared to other modes.
When I had my MK V, I selected the mode for each channel, the EQ (preset or slider) if any, the power amp wattage, then set the channel master volumes where I wanted them. With all the different circuits involved, the volumes aren't likely to be consistent as you switch features in and out.

I also just ran mine mono, so your stereo set up with a different model of amp may just not work like you hoped it would.
If you use the MK V preamp out to send to your other power amp in, and don't use extreme mode or different power amp wattage settings, you may be able to get a more consistent stereo image.

It works and I can get it balanced, it just takes adjusting with every setting change. Good thing I'm not trying to use this live.
The point (for the OP) is that different channels have different power amp volumes, so running a looper in the FX loop will indeed change volume when channels are changed, unrelated to the channel volumes.
