I'm currently building my first cigar box guitar, in fact it's pretty much finished . One of the last things I need to do is install the piezo. I've noticed that everyone seems to use a hot glue gun to mount it, but I don't have one. Is there any alternative? Can I use wood or super glue instead ?
As long as it is attached to the surface ,it will work , Not sure if there is a different sound quality with different attachment methods. I have seen them duct taped in place.
You're right about taping it in place to find the sweet spot. Some folks put it behind the bridge on the bass string side to give it more low end when the high string is too bright. Some put it in front of the bridge on the bass side for more mids. And on the high string side if too low end. Two piezos wired in series (- +- +) and placed on both sides can give a fuller sound too. Underbridge rod piezos are the ultimate but disc piezos have their own advantages.
You can wrap it in electrical tape and doublestick tape or hot glue it in. Silicone caulk works good with a two day dry time.. 3M Marine sealant 5200 is a mistake I learned twice...; )
When I run out of glue sticks I use RTV or Shoe Goo.,,.I use a drop of wood glue to tack the disk to the box, then add the shoe goo.,.,dries overnight.,.,.,I suspect duct tape would work.,.,wrap in leather or cardboard or thin pieces of wood and use wood glue.,.,
Actually I just put it on the inside of the lid (under the bridge on the bass side seemed to be the best sounding spot) and stuck a piece of duct tape over it. Is there any disadvantage to doing this? Because actually it sounds pretty good.
The disadvantage is you used the last of the duct tape.,.. lol
Lol Jerry, no actually I have about half a roll left. Camo pattern Gorilla tape, pretty tuff stuff.
Thank you, I'm seeking all the advice I can get at this point. You encase the piezo in a metal bottlecap I take it? The piezo I have wouldn't fit inside a standard bottlecap. When I built mine I followed Glenn Watt's advice and created about an 1/8 inch gap between the neck and the inside of the lid to allow the lid to vibrate. That's where I placed the piezo ,in that gap under the bridge more towards the bass side. Seems to sound pretty good but I'm no expert. I realize hot glue guns are cheap, but things are tight for me right now. I plan to pick one up asap. If you saw the tools I used to build this one you would laugh. Luckily I'm pretty resourceful and had some stuff such as tuners already lying around. I have less than $18 in this build and most of that was the box and poplar 1×2 for the neck.
great looking build are made with a small amount of instruments, sometimes not even power instruments.
