Not Sure Where All the Wires Go...

Hello All, This may not be a CBG for this group, but I didn't get much from the other appropriate group. I came across a circuit board and speaker from a Fender Mini Amp. I thought I could just wire…Continue

Thanks Paul, I might pick up a couple of different values and try them out, see what the sound's like.
Comment by Paul Craig on May 16, 2016 at 12:35am

The tin won't be an issue for the cap. The usual cap for a HB is the .022uf and .047uf for single coils, but you can use whatever you want. The higher the value the cap - the more treble gets bypassed to ground. So a.047 cap would be darker sounding than an .022 cap, it's a matter of personal taste. You can use anything from .001 to .1 or go super bright tone with just a volume pot without the tone pot & cap like EVH.

If you need any help their are diagrams in this forum or you can check out Seymour Duncan's website for wiring schematics.

It's a 4 wire Paul. I wasn't sure whether to go for a 22 or 47 with it being my first tin body. Which do you reckon would give the best sound?
Comment by Paul Craig on May 14, 2016 at 2:07pm

Just make sure none of the positive wires/terminals touch the body which will be all ground in this case.

Is the HB a 2 wire or 4 wire pickup? 4 wire pup could get a coil tap for a little more options. Using a .022uf cap on the tone pot?

Just a quick one before I start soldering up, what's the best way to wire a single humbucker, volume & tone on a tin body cbg? Do I just go for it with a normal wiring diagram or is there anything in particular I need to change with the body being metal, i.e. Is the body going to short out my circuit?
I built a beer can mic with a volume pot a few weeks back and had to take out most of my ground connections as well as trying to wrap the pot in insulation tape just to make the bloody thing work once it was in the can.

I came across this and think that I may be able to put something together

I used a Radio Shack piezo and left it in it's plastic case to try out on the under side of the LPG build that I did. The piezo only touches the edge lip on the inside of the plastic case.

The good: It works and unwanted noise is very minimal.

The bad: While unwanted vibrations are block, so are the wanted vibrations. Very little sound comes through.

So bottoming out the piezo in a plastic/metal cap, or putting it on a bed of hot glue, or applying with a layer/layers of double sided tape or applied directly to the box remain the best ways to do piezo's.

For a good sound sample Brian, step on a cat's tail.  That should give a close approximation. ;D

People encase piezos both the change the output sound and to prevent feedback.  An uncased, open piezo is a caterwauler that is so sensitive it will even pick up air movement within the git.  A piezo pretty much has to be encased in something to get it to perform correctly.

You can of course remove it from the housing and then encase it in something else... or you can purchase pre-wired bare piezo discs for a lot less money than encased piezos usually cost (ie, the "Radio Shack" kind).   I would recommend a standard size of 27mm.  The larger the piezo, the more volume and richer sound you can get.  27mm is the easiest to acquire and because of mass-production, the cheapest.

Comment by Brian Revels on April 1, 2016 at 11:22am

So I see a lot of people encasing their Piezo Pickups in hot glue, bottle caps, foam tapes, etc... Does anyone have a sound sample of one straight out of the package (leaving the disc in the housing)?  I know it's originally made to be a buzzer.  Is it the vibration of the crystals against the plastic housing that gives it a different sound, and why folks de-case them?

Comment by Wayfinder on March 30, 2016 at 10:55pm

Darryl, if you use the same git, there are all sorts of mp3 recording units on the market for not much money.   Or you could use a digital voice recorder, which you can often get for around $30 to $40.  Smartphones also have recording software available.  In any of these solutions, simply start recording when you start playing and if you do something awesome, you'll have it!  : )
