Parker fly acoustic pickup quit. When the red button is depressed all my gain is gone from the magnetic pickups and from the acoustic pickup.

I am no expert about such things but the electric guitar pickups work with steel strings, wouldn't work if the strings weren't steel - the pickup is a coil of wire and the vibration of the steel string generates an output in the coil the amplifier can work with.

The pickups of the acoustic guitar are presumably glorified microphones that would usually work in a similar fashion to the above, by generating an output but if they are active devices they will need a power supply in order to generate an output, something a standard amplifier input will not provide.

An active device either needs an independent power supply to make the device work like a radio needs a battery or the device will create the output by varying the current flow of the voltage applied across it.

What is the impedance on the devices? It sounds to me like the amp and the pickups are not rated for each other.

Hi,

Apart from the Guitar Brand a common issue with electric guitars is in this switch, 90% of this problem goes away with a good cleaning spray while other 10% is due to a loose wire connection at the switch solder block.

You can try repair it. They are pretty basic. I would look for poor solder connections, and reflowing all solder joints in it would be prudent.

The hum is likely from a gain stage with a bad solder joint on the input isolation capacitor. Also check other wires and check for bad solder connections on the pickup connections as well. It can even pick up hum through a bad shieid/ground connection in the jack on the guitar

The output of this is fairly low. Do make sure you have steel strings rather than bronze for magnetic pickups like this. Make sure this pickup is oriented per the instructions.

The Marshall is a super clean acoustic amp.

The POD is overloading the amp.

Try the electric guitar input and keep the gain on the amp down, keep the EQ level and use the POD and the end volume to adjust the final volume.

The normal inputs is for a low output acoustic pickup - the POD is a high output electronic source.

Start with the Marshall gains low and get the clean sound good, then work on the gritty sound.

The amp is voiced for a sweet clean sound - if you want grit'n'ball change to a 50w Marshall valve head and a 4 X 12 cabinet.

Horses for courses

This may be strictly magnetic pickup from nearby sources of transformers, ballasts or other motors that generate these magnetic fields. Humbucker pickups have hum cancelling windings that PARTIALLY remove the hum. Wires from pickups to other components should be twisted to help cancel the problem.

Pickup height on electric guitars is an oft debated subject. It's more about personal preference, ..BUT there is a bit of science involved , and here is some real simple "String Theory" for electric guitars. Your pickups are magnets essentially, with little winds of copper wire - this is how a transducer (pickup) picks..up (hence PICKUP) the sound of the strings. Strings are steel , most brands have Steel wrap around a Nickle core, ..it is ALL attracted to magnetics. You've played with magnets before , right? What happens when you put a magnet close to metal? It...PULLS it , right? Now , here's the deal about THAT , for guitars. The closer you get a vibrating string to the pickups , the more signal the string will produce , BUT if you get TOO close, the pickup will start pulling on the string too much (remember..magnetics) and that will reduce the amount of sustain on a string(s), and may even hamper actual tuning depending how strong the pickups are. Of course there is the "Duh" factor - having your pickups so high that your strings actually rub them as you play , ...don't do THAT! Best advice: Keep the pickups about mid-way. Not high enough to cause any noticeable problems, but not too low to sink them below the pickup rings (the plastic rectangulars that surround the pickups.
