Radio interference When recording an acoustic guitar, radio interference is getting on to the recording. The setup is an acoustic guitar with a piezo pickup then plugged in to an interface and from there in to the computer. The interference is so great you can clearly hear the radio station. This does not happen with microphones. Clearly, the guitar and/or instrument cable is acting like an antenna. I use a power strip that is supposed to have EMI, RFI and Surge protection, but that doesn't help. What to do?

    The cable is a Quantum Audio Designs Q-2100 instrument cable. I know it's not an expensive cable. I've also just noticed that by simply touching the connection right where it plugs in to the guitar, that it decreases the volume of interference. So I'm guessing there is some shielding that needs to be done, and perhaps a high quality cable?

    What brand and model cable are you using? Is there a lot of equipment running in the room at one time?

That sounds like its the cable. I make my own cables so let me know if you'd be interested. They have a copper shield with a polymer that blocks out noise.

My Ibanez acoustic electric has very weak volume and makes a constant white noise hiss when plugged into an amp or sound system. Batteries are new as is the pre-amp and under saddle piezo. Ideas?


It will be either the saddle pickup or the guitar pre amp. If you unplug the pickup and the hiss is gone, there was your fault. Otherwise fit a known good pre amp.

I pressume that martin thinline preamp pick up has two pick ups ?


your pressumption would be correct. The Thinline 332 runs under the bridge saddle, and the Piezo is attached ti the inside of the guitar body, tilt your guitar and have a look inside, you may be able to see it.

Epiphone EJ 200 CE/AN Electro Acoustic Guitar Wiring Diagram


Does this guitar have a esonic 2 system, if so the other pickup is piezo pickup located under the saddle, there should be two wires coming from the pre-amp just remove the pre-amp from the body and make sure that the two wires are still plugged in and attached to the pickups, these are plugs like a small headphone style plug, just check these and the wires are held in by small wire clips,one of the wires may have came out of the clips...hope this helps I will look for a schematic for you and post it if I find one...Good Luck!!!

Heavy radio interference when the amp is in use. It's worse at night. I'm using a Taylor 816 acoustic electric guitar with Taylor's balanced quarter inch to XLR cable into my Loud box Performer. Nothing...


Well, the first thing is to find if it is the amp or the guitar. Plug in a guitar cable WITHOUT being in the guitar... is the interference there? If not, the pickup of the interference is in the guitar electronics. In either case, bypass caps need to be instaalled in the offending unit near the input to bypass the interference to ground. You will need to seek someone familiar with electronics to fix this. There is a chance that the only cure will be to distance yourself from the radio transmitter. The transmitter has to be an AM radio type as FM would not generate audio in your system.

I've got Takamine JJ 325 My problem is backround noise - What can i do ?


Acoustic guitars pickup noise almost like a microphone. You have to prevent the sound from reaching the guitar or get a solid body guitar.

Sometimes pickup doesn't work depends on what amp I use. Thanks, Ed


These pickups have a very high impedance so you must run into a high impedance input. Many amps expect low impedance guitar outputs and these piezo pickups just can't drive them.
We currently use an X2 wireless system which has over a 1.5 megohm input impedance which works well with these piezo pickups. Long guitar cables degrade the signal as well and running into a DI just won't work.

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.


If you are using a mono (2 contact) guitar cable then the output from magnetic & piezo pick-ups should be mixed together. If you are using a stereo cable (3 contacts - tip, ring sleeve) then it will be stereo with one signal sent down each core of the cable with common/ground on the sleeve.
If you are using a stereo cable into a mono amp socket it is possible that a short is occurring, which would cut the signal. I would also check your cable for poor/ shorting connections. The signal level could also drop if the pick-ups were out of phase with each other.
For more information on balancing the levels between the pick-ups see the user's manual here

I just bought a Fender VF3 electric violin. It


The piezo pickups for violins REQUIRE a high impedance input preamp.

The measured impedance of My wife's violin is on the order of 2 megohms.

It sounds like you are having cable connection problems. If you don't have a preamp right at the vilin, then use a VERY short high impedance instrument cable.

Most of the Focusrite mic preamps I looked at had input impedance around 5K ohms which is unsuitable for the piezo pickups.

Here we use an Autolycus pickup on an acoustical vilin and an X2 wireless system. The transmiter has a very high input impedance and the resulting system sounds like a violin.

Some amps themselves DO have a high input impedance, but many designed for guitars do not. Long cables, especially low impedance ones, load the piezo pickup with capacitance which clobbers the high frequency response.
