BACK OFF...passive control.

[deadastronaut]

still on it...

tried the 220p to ground (as per signal pad, apparently, ) nope...still clicky...

i will try 100r's on in/out....

but i think i'm on a hiding to nothing with this....hmmm....

mutha @#$%ing switch..

[deadastronaut]

tried 100r's in/out ...

nope...

god knows how EHX signal pad gets around this....'IF' it actually does..


anyone got one?...

[stallik]

Stupid question Rob, is it boxed up?

[deadastronaut]

yup...thats whats annoying...

[deadastronaut]

i found this on the EHX forum....wtf?...its passive

''I bought the Signal Pad specifically to hit a sweet spot on a fuzz that I can get by using the guitar's volume control. I figured a pedal-based "set and forget" volume control should be able to do this job.

And it almost does - unfortunately as some previous posters noted, the signal pad seems to reduce treble at the same time as it reduces the volume. So while I can get the right amount of fuzz, I also get a muddier tone, which isn't ideal for what I'm trying to accomplish.

There are 2 more things I noticed about the Signal Pad:

1 - When engaged, I also got additional noise in the chain - which really shouldn't happen considering I'm reducing my total output.
2 - I opened up the pedal and expected to find a pot, a switch, an LED, and a battery - but there are some caps and transistors in there as well. I'm wondering if they've over complicated what should be a simple circuit and lost something in the process...

On the upside - as other have noted, the true-bypass works fine and the pedal is transparent when it's off, and it sure is built solid enough.

another post....

''The other thing that irritated me about the signal pad was a loud POP when you turned it on or off. I got mine new and didnt abuse it, and it popped loudly when using it.''


bummer...

so a passive vol footswitch is a no go then......grrrrrr...

looks like i'll have to go buffer/9v then...ffs..grrrrrrrrrrrr

back to the drawing breadboard then...

[deadastronaut]

and another.....

It sucks tone very much when engaged, transparent when off. The weird thing is that you'll find a complex circuit inside, not a simple pot, but it makes me scratch my head.....''


hmmmm...

AMZ has some low voltage stuff here

I wish I could offer more help with the passive idea but my knowledge is still limited.

[deadastronaut]

^ ooh that looks interesting...

[stallik]

Still can't understand why mine doesn't pop. Perhaps it's the spaghetti wiring and Goliath welding

[deadastronaut]

yeah strange....ive tried 2 switches...

its not as loud as the usual ungrounded input 3pdt 'pop'

but i'm just being a fussy bugger...just noticable with dirt/delay...hmmm

[samhay]

If you don't mind this not being true bypass you could try this:

[deadastronaut]

cheers sam....

i did wonder about switching from the wiper instead.....

ive soldered 1M's across both jacks...seems to be a little better

more usable anyway...

I don't have the energy to solder up a switch right now so I can't try it out. I like Sam Hay's idea, it keeps a constant ground, right? Maybe that's the answer. Here's my variable r idea, might be the worst yet, I dunno.

[deadastronaut]

cheers guys, i'll give these both a go....

[Mgt280y]

I built up one of these with a Dpdt and no click but I don't have the led is that the source of the click? I'll post a pic of how I wired if it helps

[stallik]

My no click is also without the led but I'm sure DA tried it without

[Mgt280y]

Right I lost track of what clicked and what didn't

[deadastronaut]

same here.....


i bet if i wanted a click pedal it wouldn,t

Something I posted earlier in this thread

An untested idea

Wire the input to "top" of the volume control
"bottom" to ground
Connect a >=10meg resistor between the wiper and "top"
Connect the wiper to the output
Short the >=10meg for full volume
You always have a connection do not know if the 10meg step will be heard

Not ideal

Will mess with the taper and loading, however it should reduce the pop. 
Maybe if you use the control where it does not have the wiper near ground it might work well enough.
Could use a resistor between the "bottom" and ground as a limit
