I appreciate the insights on the Mark VII. I may have to try one out at some point...
I hear you. A single MV seems like a basic requirement. However, Randall Smith had this to say re the MK7: “I wanted to focus completely on unadulterated tonal impact, and, to that end, the output control and the Solo function [found on the Mark V], useful features as they are, did reduce that tonal impact somewhat because of the extra tube stage and the attenuation that occurs through the controls and all that. So if that feature is vitally important to someone, they can still get a Mark V and enjoy it, but I think the time was right to change it.” So, he makes a case.I just want to say that I for one would very much prefer to have an over all master volume. Different size venues, indoors, outdoors,etc, and I will be needing to adjust volume. If I dial in each channel to what I want each channel to sound like I don't want to then have to go and adjust the volume on each individually. There have been plenty of times when at a gig I might bring up my over all volume a bit as the gig progresses. Bummer because I really would like to have a go at this amp but this is putting me off.
I thought about that. But what would you suggest? I’m thinking some sort of high quality EQ. I like the Empress ParaEQ but I think you’d have to have the boost engaged so that you would have some room to cut or boost, if you follow.Put you a volume control in the effects loop. Make sure it's a good quality pot. Take it out of the loop when you don't need it. When in small venues put it in and use it to turn down the overall out put. All channels will be affected equally.
Agreed, a good low Z volume pedal would work as well.Put you a volume control in the effects loop. Make sure it's a good quality pot. Take it out of the loop when you don't need it. When in small venues put it in and use it to turn down the overall out put. All channels will be affected equally.
I used to have a dual rec rev f. Biggest mistake ever was getting rid of it to get a roadster. Then got a multiwatt but still didn't catch the rev f sound, tone, feel, or nasty but not fizzy gain as the rev f. Now the rev f didn't have a solo boost. So what I did with it was to wire a regular volume pot with 2 quarter inch jacks via really good short 4" guitar cable and plugged it into the in and out of the efx loop. I then turned on the effects loop with the foot switch and rolled back the volume a little. Switched back and forth till I got the right volume difference for solos. So the rhythm volume was efx loop on, and solo was efx off. Worked great for a good year. Then I went from pedals to a Tc g major and I used it to do a 3db drop on all rhythm presets and 0db drop for solo presets. Thats how I used it in every amp since the revf. As for overall volume you could just use a really good volume pedal and turn the efex loop on and keep it on top or behind the amp to get the desired overall volume to the room without adjusting and rematching you channel volumes. Or if you use the efx for your efx then just add the above method or maybe you already have an effect that can act as my tc does. My tc can also drop the overall volume by twisting the out put nob on the tc. I'm hoping this makes since. Its tough to explain when I'm not looking at what I'm trying to explain. As for an amp that has a solo boost but not a global volume control I'm not sure where the boost pot is in relation with the efx loop. But you should still be able to adjust the boost pot to get where you want. Better than adjusting all volumes back and forth. So if you do go try one out and you fall in love with it, there are ways to have a global volume control without having one in the actual amp. So don't let that be a deal breaker for you. And when I used these methods on my revf and my uber-censored- it never affected tone. Just use good efx or parts to make a volume box or whatever, to do it. Hope this helps. I drive 18 wheelers and have been up since midnight and I'm not even sure if any of this makes since to me as I try to proof read this.I thought about that. But what would you suggest?

The squeel issue to me indicates some circuit confusion, which makes me think of midi. I used to use midi back when it was developed with keys and computers. I thought maybe a bent pin short in a connector. But then you said intermittent. So that is puzzling and makes me think of the circuit with a chip that handles the signal routing has a static problem causing it to malfunction, or possible micro ground leakage. It's the kind of thing that manufacturers will say is impossible, but believe me midi overloading can do weird things. I trust you completely cable everything before powering on, that is important. There are memory schemes involved, power on and off properly several times with your default settings switches, connectors and all. If you were to run it one way, power off, change something especially switches, and power on again, it could momentarily confuse the circuit routing. Just me I would best practice my most common settings, then change them after I was up and running. At least it will give yourself a base point for troubleshooting. Sounds like either a connection but the squeel makes me think data confusion which is chip related. Is have mesa replace the chip if possible.Agreed for the two times I had the issue. Odd that I never encountered such problems with the JP2C as I never purposely set the channel selector to CH2 before using it with the Footswitch.
Also, I had too issues, one I had disclosed and the other I left out: Use of the amp without the footswitch. This should not happen. The first feedback squeal like a tube was microphonic occurred right after taking the amp out of standby, amp was on CH3. There was one time it took almost 2 seconds to change from CH2 to CH3 after I moved the mini toggle from CH2 to CH3. It does not state in the manual that the footswitch is mandatory.
If you use midi, you are not supposed to use the footswitch at the same time. That is the only part in the manual that discloses permanent damage to the amp and or footswitch.
You can daisy chain two or more of the same amps and control them with one footswitch. It is outlined in the manual how to do that. I have done this many times with the two Triple Crowns. But I only have one Mark VII and one JP2C. They are not compatible. I did not mix up the footswitch controllers either. I did notice the footswitch controllers DIN port for the JP and MK7 are the same. So it is possible to mix them up by mistake. The Triple Crown uses a different DIN style so it is not possible to accidentally use the wrong footswitch.
At the moment I do not own any midi controllers or switch gear other than what comes supplied with the amp itself, its footswitch control.
I am ok with leaving the amp on CH2 when I use the footswitch. No big deal with that. Why does it still happen when I power up without the footswitch connected and want to switch channels with the mini toggle switch? So far, this occurrence is best described as random and not frequent. If it does become problematic, I will take the proper action. It could be a preamp tube or it is something else.
The amp in general has been very stable and sounds great. Just a few observed things that has occurred over the week I have had this amp. It would not be the first time I bought a Lemon from Mesa Boogie. My Mark V90 is a prime example of such. All of my other Mesa amps are flawless in functions and I never experienced such a train wreck of issues like I have with the Mark V90. The Mark III I have owned for 24 years never failed or had any issues. Mark IVb I had for 12 years never had an issue. Mark V90, I wish I could say the same thing but I cannot, Everything else crapped out on it but have not lost the diode rectifiers yet like others have experienced. I am trying to remain optimistic here so I will refrain from digging up the past. I do not want to turd this thread.
I believe it is the mini toggle channel selector switch. First time it happened was when it did not fully engage to CH3 (was not using the footswitch at that time). Then when I switched back to CH2 and then to CH3 there was a delay of about 2 seconds before it changed channels. After the amp was off for a while, I started it up again and all was fine. I am back to not using the footswitch for the time being. I did not feel like using the 100ft cable it came with. Not sure how long it really is but it is a bulk of cable that is way too long for my particular use. May just look for a shorter cable. This issue has not shown up since then. Other than running the amp with the footswitch and channel select set to CH3 at startup, that may be an issue. Yeah, I am aware of the processor self configuring at power up, detects if a footswitch is connected, then looks at the other functions such as channel, FX loop, GEQ and stuff. JP2C has the same processor but different commands and the same with the two Triple Crowns. I have seen some funky things with the Triples when using the daisy chain setup. How you power up the amps and the one with the footswitch connected gets turned on first. I am good. I do not believe there is a hardware issue in terms of the midi controller. If it crops up again, I will have a better idea of what caused it before I shut down the amp. I may need to look at the store LED on the back to see what it is doing before I kill the amp power. So far nothing to report. I do allow for the amp to heat up more than 30 seconds before taking out of standby. That should be long enough for the processor to do its thing, unless there is a clocking issue and it locks up. Wonder if they have taken into consideration any transient protection other than the small switch mode power supply they use to power it up with. Any issue that crops up I will let Mesa handle it.

I take it it's not a mechanical switch, it's tied to voltage and the values it's passing are off, or the reading side is getting spoofed. Lol the price of convenience says workaround all day. That's how I roll. You'll still get tone. Throw a vintage Telefunken in V1. I just did, and it sounded so much better I don't give a **** about this hiss.
