I recently got a used Dual Rectifier and while the amp itself is in nice shape the footswitch looks thoroughly stomped on. It is really noisy (big pop noise) when switching between channels and although the indicator light toggles on and off, the FX switch isn't toggling the effects loop. Does anyone have any tricks for reconditioning the footswitch or am I stuck having to look at a replacement? Cheers.
 
The footswitch works via midi. The loud pops are the amp and have nothing to do with the condition of the "Big Foot" pedal. Either it sends a signal or it doesn't.

Does the FX loop switch on even thought the light doesn't work? Have you made sure that you've turned the FX loop on via the knob on the back of the amp?
 
i have a triple rec with a footswitch that does the same from time to tim e- not always thought fortunately

The light works, but it doesn't toggle it on and off. And yes, I have the assign knob set to footswitch. When in this position the loop is always on.

Uh, no...that would be a negative. I'm looking at the back of mine right now and there are TWO knobs. One to bypass the loop, turn it on globally or assign it to a specific channel and ANOTHER knob that selects the channel you're on or throws the switching to the Big Foot.

You might want to take a look at your amp again...

I don't wanna be an ass but the fact that you even thought that your MIDI footswitch was causing audible pops means that you haven't researched the problem yourself at all.

As somebody else said, if the pedal is MIDI-based, it's not the footswitch. When you switch settings on the front of the unit, it should pop the same way.

Chances are you have a bad filter capacitor somewhere on the board that is failing to filter out a DC bias on some signal path through the board. When that path is switched in, it passes DC, while other paths don't, and thus, the level jumps up suddenly.

Don't ask me to guess where the bad filter cap is on the board, though. I've never even seen one of these amps you're talking about. :)

Well, I don't want to be an ass either, but you might want to try looking at the knobs on your amp. I'm looking at the back of my amp right now and yes, there are two: "Channel" selecting your channel (1, 2, 3, or ftsw), and "FX Loop" for setting the loop (with bypass, 1, 2, 3, globally on, and ftsw once again). Maybe you want to be sure you are looking closely at your gear before making wanna-be smart ass comments to others. Thanks for being no help at all.

As for researching my problem, what the hell do you think I was doing by starting this thread? Or should I have found all the answers before asking?

You're totally asinine! My comment specifically said what you JUST did in your post. What YOU said originally is that if the footswitch is on, the loop is on. Quit being a retard and backpeddling. Jackass...

Proof:

I'm not the one who thought my MIDI footswitch was causing sound issues with my amp.

Hmm...let's see, I ask a simple question and you come straight out with a holier than thou attitude and and I'm the jackass, eh? Well, you are clearly smarter than me so I guess I should just defer to you in all your wisdom. My point is simply that since you totally omitted one of the selections on the assign knob, and offered nothing helpful in any way, that maybe you should have not posted instead of just beaking off and practicing your use of bold tags. If you have something helpful to say about how to set the knobs to get the footswitch to toggle the loop on and off then by all means say it. If all you want to do is yap and give attitude, then be prepared to take some back.

My initial response was quite humane. Your response to my initial one was where we started shooting off into some tangent of being smart asses. I don't know of an option I omitted on the assign knob. Simply, there are two knobs. One for channel changing and one for the loop. One of your responses appeared to say that if you have the footswitch enabled, the loop is always on. This is not the case. If that is not what you meant, then fine. I thought you were talking about the channel changing knob.

To answer your question, turn the knob on the right (when looking at the back) that is used for channel assignment to the footswitch option. Then, on the knob on the left, turn it to the loop on option. The solo and output knobs should work in this config (just an aside). This would be the best way to test if the fx loop working. Something like a really fast delay or a heavy chorus so you'll know it's on. Make sure you set your mix knobs for your effects loop well enough. 12 o'clock on both should be fine.

Now put the footswitch in there and test it out. Set all functions to be controlled by the footswitch. You should be able to toggle the loop on and off via the footswitch. If the light on the footswitch does not come on, it could be that the light is burnt out (is it led, I don't know). If you find that the fx loop is not coming on when you push the button and the light on the BigFoot is not lighting up, it could be that the toggle switch on that particular part of the BigFoot is not functioning. It could also be that there is something wrong with your effects loop.

As an aside, the last time I had an issue with my effects loop, the amp wouldn't make any sound. It turned out to be a tube issue. You might check the tube for the effects loop...although, if the footswitch is not lighting up and not turning on the effects loop, you'd have to lean to the toggle switch not working properly. The footswitch just sends a midi signal. The light could toggle on but the loop on the amp may not be on. This, however, is not what you're describing.

Now test the solo button. It should work as well. When the loop is in bypass mode on the back of the amp, you should get nothing from the output, solo, or fx loop. The bypass of the loop defeats the output knob, solo knob, and the fx loop. A global shut off, if you will.

As for the popping noises when switching channels, does it do it when you switch the channels using the knob on the back? That's a good way to test. I suspect it will since the footswitch is only meant to send midi messages to the amp telling it which channel to go to.

There. Successfully bypassing any smart ass comments. I own the amp, you own the amp, we can co-exist as amp owners who generally like the same sound. I'm not one for arguing over the "internets". It's lame.

And yes, I'm a pro at using bold tags. It tends to draw attention to things. And as you have pointed out my ability to take advantage of this particular BBS feature, I will assume that the attention harvesting was successful.

See, now that is a proper response. Thank you. It seems however that we still have a communication breakdown regarding the nature of the issue I am having. Your description of how the loop operates confirms the way I thought it works. I have both knobs turned to "footswitch". I realize that with this configuration that the loop should not always be on, but this is how it is working on my specific amp. In a nutshell, the FTSW setting is behaving like the "Global" setting. The light on the footswitch toggles on and off, but the light is all that toggles.

Like I said, I got the amp used, and the footswitch looks well used, so I wouldn't be surprised if the problem was just in the Bigfoot. I'm going to try a borrowed new switch on it to see if it sorts the problem. Anyway, thanks for confirming how the loop operates. Cheers.

That's plausible. It could be that the circuit that turns the light on works fine but there's a break somewhere that sends the midi info to the amp telling it to turn the loop off.
