It was suggested to me that one of my designs might benefit from a built in speaker, so I had a couple of questions about how to go about it.For starters, I was thinking about breaking apart and…Continue

Up to now I've done all my own soldering etc but recently I've been looking on-line at pre-wired harnesses.   Almost all of them include a toggle switch.   Why would you need one with just one volume…Continue

BrianQ is right.  Learning to check continuity with the ohm meter is a big part of this gig if you build amps or amplified guitars.  I’ve had to learn it, it is easy once you try.  Best of success

Red probe to positive on pickup, Black probe to ground, switch the selector to 20K ohm resistance. You should get a reading between 3K-8K? One thing to think about, cellphone jacks are stereo, output jacks on passive guitars are mono, that may be the problem, check your wiring again? Good luck

Thanks paul.  battery is good...amp is loud when i use it to play music with my phone.  i have checked over and over my wiring with several diagrams.  I now think the pup coil may be bad.  Its new, but who know.  I think I may try the multimeter thing (but don't know how) and may even just hook up a piezo i have instead of the coil to check that the wiring on the tone/vol knobs is ok.  Thanks again for your comment.

The amp is plenty enough power for a guitar. Guitar's with passive electronics work on milliamps, so a 9volt aamp is plenty of power.

 Could be that the wires for the guitar hook up are reversed, something could be defective in that part of the amp circuit or the pickup could be defective.

Have you checked the pickup with a multimeter? Can you use the phone hook up with some kind of conversion plug adapter? Battery good and power getting to the amp circuit? any burn looking or smell to any components?

?  I have a 'altoids' amp (9v battery, lm386 chip, speaker) works fine for speaker when hooked to my phone.  Trying to wire up my first single coil pup electric.  i tink wiring is good.  but no sound from amp.  Can a altoid type 9 volt amp work on a electric guitar?  starting to think not enough juice to power it.  i get no sound out of speaker.

Does anyone know what pot value works best for a piezo in a bass?

Comment by Paul Craig on August 13, 2017 at 2:21pm

It could be a lot of things including his amp, his amp's power supply, guitar cord, effect pedals, wiring in his house or lighting in his house.

Something could've been knocked loose in shipping. Did you shield the inside of the box? Also if you use shielded wire or wrap the ground wire around the signal wires from pickup/piezo to the switch/pot and to the jack, you'll have a git that is practically hum free.

Some pickup's are so microphonic that putting them in a open box will result in squealing like a banshee. I've had to make a box tight around the pickup on a couple of occasions. On one build, I wrapped the sides and bottom of a pickup with fabric covered foam(shoulder pad from wife's old blouse), worked like a charm.
