A reliable and well-designed amp is essential to optimize the music for recording and jamming sessions. Positive Grid has designed Spark, which is a 40W combo amp that allows the users to control the music with onboard bass. In addition, there are treble and mid-tone controls.
Since it’s a multifunctional amp that allows musicians to improve and refine the music on bass guitar, electric guitar, and acoustic guitar, it has become a popular choice among musicians. However, Spark has a few common problems that you need to be aware of!
Most Common Positive Grid Spark Problems
- No Sounds
If no sound is coming from the Spark, a reset is the most convenient solution. However, reset will delete all the customized settings, which is why you can try a reboot. For rebooting the amp, unplug it from the power outlet and connect it again after five to seven minutes. When the amp turns on, the sound will be normalized.
On the other hand, if the Spark still doesn’t have a sound, you can reset your amp with these steps;
- Switch off the amp and press the “tap” button as you turn on your amp simultaneously
- When the lights start blinking, release this button
- Again, long-press the tap button until four LED indicators blink once and leave the button
- It will complete the reset process on the amp
Keep in mind that resetting the amp will delete the Bluetooth pairing data. So, before connecting it with other devices, remove Spark from the recognized devices list and pair it again.
- Buzzing Sound
Buzzing sounds is the second common problem associated with Spark amp. In most cases, the buzzing sounds are a result of faulty cables and connectors as they adversely impact the amp connections. You must inspect the connectors and make sure they are tightly connected. It’s better that you take off the connections and connect them.
Also, if the connectors are damaged, replacement is necessary. Secondly, you need to inspect the cables. With regular use, the cables wear and tear internally, which is why a replacement can help fix the buzzing sound. Make sure that the replacement cables are top-notch and are designed particularly for amps.
In case you don’t know if the cable is the real issue, connect the guitar cable and move it when the volume is on, if the buzzing increases or decreases when you move or bend the cable, you need to replace the cable. The third thing you’ve to check is the shielding.
It doesn’t matter which pickups you use for the guitar, if the buzzing becomes frequent when you touch the guitar strings or other metal parts of the guitar, the shielding has been compromised. To fix the poor shielding, it’s better that you take your guitar to the guitar repair shop.
Once the shielding is repaired, the amp won’t make any buzzing sounds. Poor grounding is another reason behind the buzzing sound, which is why you have to inspect the grounding wires in the guitar and solder them.
- Won’t Turn On
If the Spark fails to switch on, it is caused by a blown fuse or a damaged power unit. The fuses are important to protect the electrical circuit from voltage or current fluctuations. If you’ve been experiencing electricity issues at home or wherever you connect the amp, it’s likely that the fuse is blown.
The solution is pretty simple because you only need to replace the fuses (the fuses are affordable). It is better to hire an electrician for installing a replacement fuse as he can check the other electrical components and fix them, if necessary.
- Playback Not Coming Through Spark
If you have connected your Spark smartphone app to the amp and the playback music is still coming through the smartphone rather than the amp, you need to check the Bluetooth, AUX, and USB audio connections.
This is because if there is more than one connection on the amp, the amp will first prefer AUX, and then USB and Bluetooth will be the last preference. So, check the connections and delete the extra connections. Secondly, in case you are using Bluetooth for playback, you need to ensure a proper connection with the app.
Make sure that Spark’s blue light is flashing before you connect the smartphone app to the amp. Then, open the Bluetooth settings and pair it with the Spark 40 device. Once the Bluetooth is connected, the playback music will be optimized. Last but not least, you should close the background apps before you connect the amp to the app.
- Zero Output From Amp
If the Spark amp isn’t giving any output on the Bluetooth-connected device, you need to check the USB cable. This is because when the USB cable is connected and the Bluetooth is enabled as well, the amp will prefer AUX, USB, and then Bluetooth.
The amp will play audio from the high-priority connection, and since USB is the second priority, it’s better that you disconnect the cable. In addition, make sure that the volume is enabled on the top panel of the amp.
- Unexpected Error During Playlist Importing
It’s common for musicians to import their playlists after they are done producing the music. However, if you see unexpected errors while importing the playlists, it’s usually caused by errors in the app where you are trying to import the music.
For instance, if you are using Spotify, it is recommended that you delete the Spotify app and reinstall it after some time – you need to reboot the smartphone before reinstalling the Spotify app. In addition to this, you could try rebuilding the playlist.
- Unable To Recognize The Device
If you are using the Spark smartphone app and see a “cannot recognize the device” error, the only solution is to call customer support.
However, before you contact customer support, you can try turning off Bluetooth on your smartphone and turning it on after a few minutes. Once the Bluetooth connection is rebuilt, try to connect the app to the amp.
- Computer Is Unable To Recognize The Spark Amp
The Spark amp can be connected to the computer for direct file export and import. However, for this data transfer to work, the computer must recognize the amp. In case the computer is unable to identify the Spark amp, you should try a different USB port (you must not use a USB hub).
In addition to this, you should disconnect the USB cable and re-plug it after some time. If you are using Windows on the computer, you must have the updated ASIO driver for it to recognize the amp.
- Firmware Update Is Failing
The Spark firmware is important to improve the functionality of the amp and enhance the features. In addition, the firmware updates provide the service fixes, which is why installing the firmware updates is necessary.
On the contrary, if you are unable to download and install the firmware upgrade on the Spark amp, it’s better that you reinstall the firmware. For reinstalling the firmware, tap on the “eject” option at the end of the firmware upgrade process and disconnect the USB cable.
Then, connect the USB cable to another port and try installing the firmware update again. Keep in mind that you should run the firmware updater as a system administrator. Last but not least, if the firmware update is still not successful, you can call customer support.
They are likely to ask for the Spark serial number, operating system version, and the website you got the update from. Once you provide this information, they will send a new link that you can use for downloading the firmware.
- Bluetooth Connection Dropping
If you have connected the Spark amp to the Bluetooth already but the connection is dropping, you need to factory reset your amp.
The reset instructions are mentioned above, and in addition to the reset, make sure that you install the latest firmware version to prevent connectivity errors. Lastly, you should try turning off the Bluetooth feature on other devices.
