I've always heard Jay-FET and L. E. D.

Usually I say led because it's quicker :)

hey this is great! I think i've got it working, woohoo my first circuit! My only problem is that the input jack switching is not working... in other words, the power is running all the time and is not switched off when the plug is removed from the input jack...

as far as i can tell i've wired everything as shown... the only strange thing i ran across is that my mono output jack has 3 terminals instead of 2. Can you suggest a place to start troubleshooting?

also, just to make sure, the circuit is supposed to work like a volume knob of sorts correct??

thanks.

i think i'll take on the BrassBlaster Bass Overdrive project next; anybody know of any other good Bass pedals to build?

i think if someone gave me a thorough explanation of how the LED and stepdown resistor should be wired to the inputjack switch it would help alot. The only example of mounting the LED i see involves attaching it to a 3PDT switch... when the 3DPT is taken out of the equasion, the LED seems to have a constantl ycompleted circuit rom + to - on the 9V battery.

This is where im stuck. The LED is on no matter what and I am unable to tell if the rest of the circuit is drawing power form the battery with no plug inserted either. Am I making sense?

i appreciate the assistance.

Well if you connect the LED/resistor combo to ground, and it's drawing current even without any plug inserted, you've miswired your input jack switch. Are you sure you wired the jack OK?

Would it be possible for someone to post a picture of their bypass wiring box?

The key is that the LED ground should connect to the SLEEVE of the input jack. Once you do this, when you unplug your guitar cable, the ring will not be connected to the ground of the input jack and the circuit is disconnected.

See the picture in this thread on how to connect the input jack.

The more important thing is that the flat side of the LED is the cathode or "line" in the symbol:

so the cathode goes to ground or the antode to ground???

question, i'm putting 3 effects in one box. only 2 jacks in and out. do i run the out from one switch to the in of the next? and hook the effects to the in and outs of the switches?
Thanks

aaron, on that board what are the input outputs?

on the GGG site he explained that the output on the board is usually the middle lug of the level pot.  so whats the input?

when using the bypass, will i still have to have the 9V+ connected to the resistor, just the lug on the switch, or both?

arg, it worked earlier and now when wiring up the bypass it's not working again.  :cry:

It has to be something simple. Just triple-check your connections.
