Hi Jim,
There has been a discussion on using multiple piezos here http://www.cigarboxnation.com/group/cbgwiringelectronics/forum/topi...
Nice looking CBGs you have made :o)

Hey fellas, can we talk about the difference between stereo and mono 1/4 jacks and what the best application is for cbgs and piezos, etc.? I have bags of both jacks and am using the mono ones for the double piezo pups that I am wiring, but want to know what I can do with the stereo ones.... (Sorry, I know I botched that sentence)

Hi David,,Do you have a drawing of wiring 2 piezo's in paralell. Also is there any trick in getting them not to feedback???

I wired a single coil pickup and piezo together using a simple passive mixer circuit rather than a switching circuit. Basically, each pickup has it's own pot so that I can control it's presence in the mix that goes out the jack to the amp. Basically, you need an equal amount of fixed resistance (I use 1kohm) in series with the hot lead of each pickup (between the pickup and it's pot), and then you can just wire the out put of each pot (I used 500kohm audio taper pots) straight to the hot lead of the output jack. I can turn the piezo all the way down for nice single coil sound, I can turn the single coil down for a jangly piezo sound, or I can mix it anyway I want in between. One of my favourite tones is to have both turned up all the way. Great mix of highs and lows with that!
FWIW, I make my own pickups using coils I scavenge out of wall wort transformers and small but heavy duty alnico magnets I ordered in bulk from mouser. I've found that pickups made from the coils out of 12v wall worts output as much signal as a standard single coil pickup. The 12v coils are also just the right width for a three string. I use three magnets, and then just wrap the thing in duct tape (I use red duct tape so it looks cool), and insert it about and inch or so up from the bridge. Works great! Much easier than winding your own, and much cheaper and much more mojo than buying a prewound pickup.
Hi Jim,
I usually go with 500k for humbuckers but only because it is what I do with my electric guitars. If you are adding a tone pot what I have noticed is that although it works well on altering the tone of a magnetic pickup it has little effect on the piezo (different pickup properties which send me to sleep if I try to read the theory behind it all). Also when soldering a capacitor in place they can easily be fried by the heat so put a crocodile clip or similar on the leg between the solder point and the body of the cap to pretect it. Audio or logarithmic pots work best because the logarithmic scale means the response to the ear is spread over the whole 1 to 10 of the dial. If you have linear pots they will still work OK but you find you dial past 5 before you notice any audio response.
Regards,
David
