Help combining pedals!

[Furandteeth]

I currently play in a two piece and at out of two amps. One is a mesa dual rectifier and one is a fender twin reverb. In order to play out of both with distortion I have to step on my footswitch for my mesa and my blues driver for the twin at the same time. In an attempt to not fall on my face during performances if like to mount these both in a single pedal. The mesa footswitch I built myself and is extremely simplistic, consisting of just a switch a jack and an led.. I would like to rehouse these to work off of one switch. I understand how to rehouse the blues driver, but how would I wire the footswitch and the blues driver to be turned on with one switch?

Just posted a very similar thing on another thread, but try this?



The third part of the relay is open which would allow you to have that as the simple part of your Mesa switch. Effectively, relay switching a relay!

This is the physical switch:



(Info found if you search "Bypassing and Switching with the CD4053 CMOS Analog MUX" on Geofex)

I really need to stop using R.G. Keen's resources and genius to make myself look more intelligent...

Probably a dumb question but the mesa footswitch is a spst and so is the replacement switch for the blues driver, could I use a dpst switch then?

Yepp that would work perfectly well Simple solutions are always great

It's a lot harder finding a footswitch that is dpst than I thought is there any way to wire a dpdt like that? Or a 3pdt for that matter?

[Jdansti]

3PDT = Three SPST switches = One DPDT switch + One SPST switch. These switches just happen to be ganged together so that when you press on the single actuator, all of them toggle at the same time. Does that make sense?

[Furandteeth]

That makes sense I just don't see how I would wore 2 pedals to be activated at once with a 3pdt. I've built a few pedals now and understand how to wire individual circuits to one 3pdt but I am just not seeing how it would work wiring 2?

I don't know much about the BD switching, so we both know about same amount of information.

The first thing I would do is look at the BD switch and note the following:

1) How many wires are connected?
2) Is it a latching or momentary switch?  You'll need to check this with your meter.

Once we know what you're dealing with we can look at options.

Here's a sneakily made diagram (via paint). You're dealing with exactly this, but ignoring pins 3 and 6 DPDT will do the job just fine, and you leave the extra pins unconnected if I'm understanding the question correctly.

John is quite right that you need to find out whether the switch is momentary or latching - we basically have to hope that whichever they are, they are both the same. Past that, you just hook them up exactly how they were before but to pins 1&2 of the DPDT for one switch, and to pins DPDT 4&5 for the other (based on my rubbish diagram)

Just to make it clear, DPDT switches come in both latching and momentary, but not a hybrid of both, so your two switches will have to be the same type

[Jdansti]

I seem to recall a gadget that you could place over two pedals to actuate two switches at once. Maybe I'm dreaming.  But you could make a custom bar (or plank) that would span between the two pedals and you just press on the bar with your foot to actuate both switches simultaneously. You'd have to account for the style of each pedals' actuator - probably one standard stomp switch and one Boss style flat tread.

If one needs to be momentary and the other latching, maybe you could mount them side-by-side and gang them together with a short bar.

I would just read R.G.'s Technology of Boss and Ibanez Switching at Geofex and pay attention to the remote switching part.

Then I would take a DPDT or 3PDT and wire the Mesa to one gang and the remote switch to the other.

you might be able to find the switch you want here. pretty cheap.

Would you not want to wire the two unused poles to ground? Would they pick up noise not being wired to ground, or is leaving them out altogether less interference for the circuit?
