No my friend ..

Its mesa amp with mesa foot switch….


Ill upload video on youtube so you can see the issue.
I have a Laney AOR Pro Tube Lead 50 watt head, 8 knob.. I bought a Laney foot switch which I assumed would switch channels from having to do it manually. When I got it, it would not do so. My memory is now fading after 12+ years gone by, but I think I was told that this pedal was meant for a combo version of my amp vs. head version. I will revisit things once I return home from Ohio.
 
You are trying to use the big foot while playing channel 3?
Yes, but it should apply to all chanels.


For example….

My Marshal has 6 way foot switch…. ( i know its a different amp) i can bring fx on/off with fx switch regardless on which channel im on…

So, why cant I do the same with Mesa? If thats not passible whats the purpose of Big Foot and fx button on it?

Or if im doing it wrong whats the right way?

It came with this footswitch …

The assign knob needs to be set to “FTSW”.
 
Yes I think Don is correct.

Yup I can see that too. Tis set to Ch 3.
IIRC, the issue is that he only wants the FX loop engaged (or disengaged- switchable) on channel 3. Unfortunately, that is not the way the Dual Rec is setup to function. Either the loop is active in the assigned channel(on the dial), or it’s off, or it is assigned to the footswitch. It does not allow the user to footswitch the loop on an assigned channel only. I think it is tied to the setup in that the solo/boost function is tied into the footswitch assign function as well.
It is a pretty straightforward footswitch setup…channels 1, 2, &3, fx on/off, solo/boost functions are available with the footswitch attached AND assigned. If the footswitch is not assigned at the rotary switch, the loop is active in the state assigned on the rotary switch, and only the channels are selectable with the footswitch.

I see. Yes that won't work. I have a couple Mesa too. Cannot set 1 channel only for loop then switch off n on.
 
If I did remember the desired scenario correctly, a solution would be something like this(I have a setup like the following for my bass/guitar fuzz-board…for when I’m using an amp with an fx loop.)

A simple, true bypass, switchable, single loop pedal. Desired fx are placed in the pedals loop, while the pedal is placed in the amp loop. When engaged the amp loop goes through the fx pedals. When the loop pedal is disengaged, the amp loop sees nothing. If this is set up with a Dual/Triple Rec(of the era in question), and the loop select feature s dialed to channel three, then the loop will be only active in channel three…and fully bypassable(via the little loop switch). This is especially useful if it is desired to suddenly “shunt” a chain of fx pedals with a single stomp.

This is similar to my switch, same builder, but different orientation of jacks(on mine).

I know it sounds silly, but if I am right about what he wants, that is part of the solution. The “solo/boost” function will be disengaged though.

Right, yeah, good thinking. I have a larger Radial one of these for 2 loops switching.
 
I made a video to show @Clockworkmike to explain easier…

Basically what i want is…

To bring fx loop on/off on whichever channel i use….
For example ….
If im on channel one I want to bring fx on/off With big foot fx button on foot switch and be able to do this on all channels regardless on which channel im on…

I hope im making sense.
 
Its already is….

Well…that is unusual behavior. Definitely not the way mine behaves. When my loop light is lit, the effects in the loop are heard as they are set. When the loop light is off, the amp goes dry…as expected.

Was the reason for my reply. Bummer….time wasted.

That is exactly the way mine works…with the assign dial set to FTSW.
 
Mine dose not and thats my problem lol
Alright….here’s a work around for you…
Take a single, latching, on/off footswitch…one that uses a standard TS jack…like a single channel switch for an amp, like a Fender amp…I used the one that I have used for decades with my Laney. You can buy one from most music stores. Plug the footswitch lead into the “1/4 inch “loop” jack. Leave your loop controls set to footswitch mode. Your “Bigfoot” will still switch channels as usual, but the separate switch will take over the FX loop duties.

Yeah…I need to clean the inside of my amp…but it works.
As I said, I’ve had that on/off switch for decades…but something like this will work…


I have one, and use it interchangeably with the one I just used…a Marshall one may work, but I don’t have one to test…
Like this:


I have no idea if the light will work though. But if you have one kicking around, you might want to give it a try. You could also make one if you’re feeling crafty…I made one in an electric light switch housing once, along with some other junk I had laying around. Point is, it will override the midi switching for that feature…this is likely the problem…either the amp relays, the cable, or the “Bigfoot” switch…this will/should bypass it…it does for me. I just fired it up to test.

Yeah…it sucks….the big switch isn’t working right for you, but at least they built in a redundancy to remedy the possibility of failure.
