Cheap homemade pickup for your acoustic instrument

I have several acoustic stringed instruments. I’m not very good at playing any of them, but I have a lot of fun trying. Mandolin, ukulele, banjo, and a handful of guitars.

When playing with a drummer or trying to get a recording, it’s nice to be able to plug in an instrument and get some extra volume. Plus, with an electrified instrument you can always add pedals, post-processing, and other effects to alter the sound a bit.

I’ve done a permanent install of an under-saddle pickup on a guitar before, but I didn’t want to spend the time or money on each instrument to get all the instruments upgraded.

I’d heard about homemade piezo-transducer pickups before, so I thought I’d see if I could make one my own. Sure, you can buy cheap ones, but where’s the fun in that?

So, I made one myself. Total cost was under $6. Here’s the finished product, in all it’s DIY glory:

The finished product

Parts list
1. Piezo transducer. Radio Shack part number 273-0073.
2. 1/4″ mono jack. Radio Shack part number 274-0340.
3. A length of 2-conductor wire. I used some leftover 18-gauge wire from a garage door opener.
4. Some electrical tape.
5. Some blue painters tape.

Tools aren’t required, but a wire stripper and a solder gun are useful.

Assembly instructions
1. Remove the transducer from the plastic housing. I used a small slotted screwdriver to pry the top off. Be careful, or plan on another trip to Radio Shack and another $3.

2. Strip insulation from both conductors on each end of the wire.
3. Connect the two leads from the transducer to the two conductors on one end of the wire. Insulate bare wires with electrical tape.
3. Disassemble the jack.

4. Slide the jack housing over the other end of the wire.
5. Connect the conductors on that end of the wire to the two connection points on the jack internals. Solder or tape the conductors in place.
6. Screw the jack housing onto the jack internals.

Connecting the pickup to the instrument
I used blue painters tape to affix the transducer to the top of my mandolin, just below the bridge. Test out several locations on the top and back of the instrument for best sound.

On my ukulele, the best-sounding location was on the back:

When finished, plug in, grab a beer, and bask in your electrified awesomeness.

If you’re bored, listen to my first electric mandolin recording experiment: Ashokan Farewell, recorded as two A/B inverted parts using my standard recording tools.

The best electric guitar for young players and little hands

I’m a firm believer that the best way to get your kid to quit playing guitar as quickly as possible is to get them a crappy instrument. If that’s your goal, hop on over to Costco and get whatever combo pack they have in a box. Get a 12-pack of socks while you’re at it, to make the trip worth it.

Instead, if your goal is to have your child build a lifelong relationship with music — a worthy goal, I think — then you need to get an instrument that doesn’t suck. In fact, it should be at least good.

Of course, you don’t want to risk buying a $3000 Gibson only to find out that little Timmy takes to the guitar like a cat to water.

So, it needs to be cheap. Save up for the Gibson for a few years.

It’s also easy to forget that your young Jack White has tiny hands. That full size guitar that you have had stuffed in your closet since college is about as easy for your kid to handle as a refrigerator.

Cheap, good, and small. The choices narrow.

So, a recommendation. Get this guitar, now:

Squier Mini

This is a Squier by Fender Mini Strat electric guitar. It’s around $100 everywhere. Musician’s Friend, for example, sells it in two girl-magnet colors.

Not only does it not suck, it’s actually quite fun to play, and sounds good too.

Problem is, it’s still not good enough out of the box. It doesn’t stay in tune at all. An out-of-tune guitar is hard to play, and un-rewarding.

Planet Waves Auto-Trim tuning machine upgrade

The best thing you can do to improve the playability of this guitar is to put some decent tuning machines on it. Like the Planet Waves Auto Trim tuning machines.

While poor-quality tuning machines abound on most cheap guitars, the overall quality and simplicity of the Squier Mini is, IMO, better than other similarly-priced guitars. And it’s smaller and easier to handle for little hands.

Replacing tuning machines is a simple do-it-yourself project. Outpatient surgery for guitars. Here’s a useful how-to.

For $150 total, you’ve got a very playable instrument that should work well for years.

Cheers!
