Question about Audio Players & Recorders

Open Question

My guitar processor (digitech RP70) is softly buzzing but no audio or lights come on, hopefully not the transformer (only part i know.) Also, when I felt around, this one small circutboard part (having 2 black rectangular parts [clamped top to bottom] in front of the power supply plugin [circ board space labeled "D3"]) get's really hot. I've just had it sitting a few weeks and now it doesn't work. It that just somthing like a small part replacement,maybe the part that's hot?....... oh and also my alarm was fried during a lighting surge or something........Is that a simple fix? (maybe like ordering a trnsformer and soldering it?) thanks jim :)

I have a Digitech RP70 guitar processor. Both of the foot switches are garbage! Can they be replaced?

I also have an RP70 with the same problem. You can fix it, but know what you are dealing with. I love the sounds I can achieve with the unit (hard to replicate). Open the unit up by removing 4 phillips head screws on bottom and remove plate/cover. The poor design is the rubber snubbers on the inside of each plastic foot switch. The rubber snubbers press against switches that are part of the circuit board. You have a few ways of adjusting the foot switch tension: 1. Tighten or loosen the 2 screws of the circuit board closest to the foot switches and check the response; 2. If that doesn't work, insert tiny washer (s) under the rubber snubber(s); 3. I did all of the above and continued to have inconsistent responses until I just left off the bottom cover which effects stress on the unit's frame. I keep it on a very level location and have had no more problems.....except, it is exposed to the dirt etc.

The foot pedal (not the switches) on my "DigiTech RP90 Modeling Guitar Processor does not will move but it changes nothing.

All DigiTech expression pedals use an optical system instead of potentiometers.

Either the light is broke, or the filter.

The filter protrudes from the bottom of the pedal, and is darker at the top and gradually fades to clear at the bottom. If this breaks off, then there's nothing to limit the amount of light to the optical system.

If it is the light, then you'll have to have it serviced by someone qualified to work on it. Your local music shop should be able to help you out.

Hope that helps!

Vocalist live 2 problem. power to unit OK , lights up. Guitar output OK. No tuner, no vocal output.

NO power light or audio from Digitech Vocalist 2 live. Check that your power adapter is for 9 Volts AC (not DC like most pedals) and is rated at 1300ma or more. A DC adapter MAY light up the unit but not make it pass audio. Lights can be lit but that is NOT an indication thaat correct power is applied. They likely use the AC input to generate both positive and negative voltage within the unit. The use of a DC adapter will prevent generating one of these required voltages and prevent audio from passing.

Hi having trouble when i plug guitar or mic into the neo. when i raise the trim to hear the input, the re is a big buzzing sound that just wont go away... any ideas?

Do you have any light dimmer in the house?
Are you using humbucking guitar pickup?
Do the the buzz change when the move the guitar around, it may be picking up radiate magnetic field from the transformers of the equipment.
The preamp is very sensitive with very high gain circuits that amplify signals in the millivolt range, so godd shielding and grounding is needed.

Hiwhat is the best way to connect my DigiTech RP10 to my Marshall MA100H Guitar Amplifier

Read your manuals for both pieces of gear carefully first. You only have one amp so you won't be able to take advantage of all the FX on the Digitech as a lot of them are designed for stereo. The Digitech manual shows guitar into the Digitech and output from the Digitech into input of any guitar amp. Since you have a Marshall and can already get some great sounds by running your guitar straight into the Marshalls input, you would probably be better off using your Digitech in the FX loop. Run a guitar cord out of the send on the loop into the input of the Digitech and a guitar cord out of the left / mono output jack on the Digitech into the effects return jack on the Marshall. Start out with the effects level on the Marshall all the way down. Do the same with the Digitech with both the input and output levels. (Read the manual carefully) I think the choice of the Digitech isn't that great because it is already trying to reproduce a lot of what you can already get with just your Marshall but with a little experimentation and some careful adjustments you should be able to add to the sound of the Marshall. Hope this helps.

No vocal sound

It sounds like the guitar level input to the unit is too low.

NOTE: With this product you MUST use an amplified or electric guitar that has a preamp within it.

If you have a straight guitar that does not have an amp in it, buy a preamp to first run the guitar through.

Digitech RP3 Guitar signal processor only lights up.

Check that connectors are seated AND the input and output are correct.

Sometimes1/4 inch plugs are not seated correctely. The power adapter plugs are notorious for not making contact.
