DigiTech RP70 Troubleshooting
This page will help you troubleshoot problems dealing with the DigiTech RP70.
Footswitches Do Not Work Properly
The footswitches are not working consistently or are broken and do not work at all.
Footswitches Are Stuck
Dust or debris may be under the footswitches, causing them to stick. Refer to this guide to remove the footswitches. Gently wipe clean or use a can of compressed air to clean the underneath. Reposition the footswitches on the device. Press them several times to test for further sticking.
Footswitches Work Sporadically
When pressed, the footswitches do not work consistently. This most likely indicates a short in the corresponding motherboard component. Remove the motherboard to check for a loose solder joint or damaged component.
Footswitches Are Broken and Not Working at All
As the device is primarily made of plastic, the footswitches will not hold up to heavy stomping or usage. If the footswitches appear to be broken or are not working, refer to this guide to replace them.
Footswitches Are Missing
If your device is missing one or both footswitches, refer to this guide to replace them.
Sound is Distorted
When the device is on and connected to a guitar and/or other devices, an unwanted buzzing, hissing, or humming sound occurs.
Note: First, unplug the device from the wall outlet and disconnect the cables to all other devices to test it by itself for the problem.
Cable is Not Plugged In
Check the back panel of the device to make sure the power supply cable is fully and securely connected into the correct jack. The power adapter cable should be inserted into the last jack on the right or the back panel. Then, plug the adapter fully and securely into a power supply outlet. If the distorted sound continues, replace the power supply cable.
Wrong Selection Chosen Between Amplifier and Mixer
The button on the back panel of the device that is used to switch between the amplifier and mixer is on the incorrect setting, causing the unwanted sound. Change the button setting for intended usage.
Cables of Attached Guitar and/or Other Device
When the device itself is not the source of sound distortion, check the cables of the guitar and any other attached device. Often, a worn cable is the source of the problem. Make sure attached cables of other devices are fully inserted into the correct input or output jack on the back panel of the device. If the sound distortion continues, test the individual cables of the guitar and all other devices. Replace them, if necessary.
Shared Power Output
Unwanted noise or interference occurs as the device is sharing with multiple pedals on a pedal board setup. Or, the device is sharing power with nearby electronics. For less sound distortion, switch the device to an isolated power supply or unplug other electronics located close by.
Input/Output Jacks are Loose or Damaged
The solder joints of the input/output jacks may be causing loose connections, which result in distortions in sound quality. Another cause could be damaged jacks due to cracks or corrosion. Refer to this guide to replace the faulty jacks.
Device Will Not Turn On
When the 9VDC power adapter is connected there is no power going to the device.
Missing Power Supply Adapter
The device is supplied power by an adapter cable. It will not power on unless it is plugged in. If your device did not come with the adapter or it is lost, replace it with a compatible power adapter.
Faulty Power Supply Adapter
The device will not turn on because the power supply adapter is damaged (or worn). Replace it with a compatible power adapter.
Faulty LED Light Indicator
The device is on, but the LED light does not turn on to indicate this. Use this guide to check the LED light for loose soldering or damage. If necessary, replace the LED light.
Power or Sound Randomly Cutting In and Out
The device turns on, but it either randomly turns off or loses sound. This likely indicates a short in the soldered internal components on the motherboard. Use this guide to check for either loose or damaged motherboard connections. Replace the motherboard if necessary.
Although the power is fully inserted into the device and securely plugged into a power outlet, it is unresponsive and not turning on. This likely indicates that multiple components on the motherboard are worn and damaged. Refer to this guide for motherboard replacement.
Device Does Not Work Correctly With Guitar or Other Devices
The device is not working as it should when connected to a guitar, amplifier, and/or mixer.
Volume is Not Turned Up
Check to make sure the volume control on the pedal has been turned up enough. Likewise, check the volume control of the guitar and other connected devices for the same.
Guitar, Amplifier, or Mixer is Not Plugged In
If the guitar cable is not plugged into the input jack of the device, no playback will occur. Likewise, if the amplifier or mixer is not plugged into the output jack, the device will not work. Check the back panel of the device to make sure the cables of the guitar and the amplifier or mixer are fully inserted into the correct jacks.
Device Power Supply Does Not Match Guitar Power Supply
Check the voltage, polarity, and amperage of the pedal and the guitar to make sure they match.
Incorrect Cable Connection
The pedal has a tip-sleeve (TS) unbalanced cable connection. If the guitar cable connector is a tip-ring sleeve (TRS) balanced cable, the pedal will not work with the guitar. Switch the guitar cable to a TS unbalanced cable.
Difficult to Change Default Sound Effects
Navigating through available effects to find, store, and/or change the default effect settings is difficult
Learning to Change Effects is Difficult
Reread the section of the user manual related to changing effects. Due to the variety of effects available, referring to this section of the user manual multiple times while gaining experience with the device's setup may be necessary.
