When i'm on clean sound the machine sounds ok, but when i switch to other effects on factory setting the effects sound level cut down tremandously. it just sound like being muted or being **** in. any solutions? many thanks

check out your input grounds on your amp

That unit has a digital reverb and tremolo that can not be turned OFF with your foot control, meaning this small sound card is always on. Even though that level is on "0", it is still always on. If it has a problem within it, it will put noises into your sound. I would recommend opening the amp, look for the power to the effects card and unplug it to see if it goes away. It should be a small card resembling a sound card from a computer mounted off to the side. It should have a red and a black wire plugged into it. Wiggle it and listen for a change, dirty connections on that plug could do that. Unplug it completely and listen. This would only remove the possible interference of the card, you would still have sound without effects. Regardless of the brand, those cheap effects cards are usually more trouble than they are worth. They only have a few samples of effects, not the actual effect. I hope this helps, I know it is a great sounding amp but, those effects cards are the weakness of amps today.

Line 6 connected to AC power and LED showing power to unit. Guitar into effect input, effect output to guitar amp. Does guitar make sound through amp in bypass mode? No then check cables...yes then use foot switch to turn Line 6 effects unit on. Adjust control knobs for desired effect levels/settings.

If pedal provides no effects...off/on switch defective or internal electronics in need of repair.

Hi J Wade. I'm Dave P. I'm not a guitar amp expert or technician but I've been using amps and effects for 35 years and there are a couple things I can suggest.

That kind of periodic noise/switch noise can be a symptom of having the polarity of the amp reversed. If your amp has a 3-position OFF/ground switch, try reversing the ground. If it doesn't, take the plug and turn it around. Just don't get near a microphone unless you're sure your amp is grounded the same as the P.A. It could fry your lips off.

Dirty switches to that too. You said the noise is in time with the delay's tap time which is set by a foot switch. If tapping that switch the first time generates a pop, the delay may have catch it and is repeating it. Turn off the amp, remove the delay foot switch and turn it back on. Still noisy? If not, give the foot switch a good cleaning.

When you turn the EFFECTS knob up, is it scratchy? Might need the potentiometer cleaned. What happens when you specifically turn the DELAY level down all the way while using the other effects? Noise still there?

That's all I've got. Hopefully, it was helpful. Don't wrack your brain over this too much. There could very well be an internal problem with your amp that will require a trip to the shop. You don't want to open it up yourself. Rock on but be safe.

If the sound you when plugging in the headphones is coming from the main speaker, it is just the interupt contacts on the headphones are making or breaking contacts. This can be a good sign if there is volume to it.

Make sure the plugs you are using are the right length for jacks in the Ibanez as there are 5 lengths in use.. If this just developed, the length issue is not a concern. If the jacks are loose, snug them down, it may be a faulty ground relying on the chassis contact with the jack.. It may be a broken wire. It can also be a dirty switch contact or dirty level control, especially the standby switch. make sure they are clean with some contact cleaner. Make sure your level is turned up too,

If you have effects, or a preamp on the guitar, make sure they have fresh batteries or good power connections and are not on mute.

Internal failure... take in for repair. It is NOT DIY unless you are electronically adept and have necessary equipment to repair it.

That is the way it is supposed to work... It is a level control to control the level sent to an EXTERNAL effects unit. What external effects unit are you using? Brand and model please. If you proportion more to the effects loop, you want to make sure the EXTERNAL effects unit is on and its gain controls are up. The foot switch input should control the EXTERNAL effects unit when you plug the footswitch into the EXTERNAL unit. The footswitch input on the amp itself has NOTHING to do with the external effect loop, it only affects the amp's own DFX unit.

I have the Boss ME 50. Here's things to try. Use wall outlet to power the 25 instead of batteries. Have volume on amp up, volume on pedal all the way up, volume pedal all the way up(depressed), no gain on amp(use clean channel or clean setting if only 1 channel)effects on amp off(reverb, chorus, delay, boost, etc.) mid range knob below 5. only 1 pickup on, guitar tone knob all the way towards treble. If this puts you in the ballpark you can then make slight tweaks to any of these settings. What we're trying to do is not run a dirty sound from the pedal board into an amp with dirty settings. That double dirt often causes a muddy sound. Aside from that you can back off on various effects in the patches. My 50 has a list of the patches and factory settings, so if the drive, for example is set on 8, I might back it off to 4, or the compressor, or the delay, etc. If you like the sound save it. If not continue on. Start with the amp 1st. Higher output tubes(such as JJ's produce a cleaner sound. Also the demo you heard was not coming from your guitar speaker which may not be on the clean side.

You MAY be overdriving the sound card. Near flat should work for vocal, but setting the levels throughout the mixer is important as well as the sound card. You can use the LOW CUT to reduce hum if you have noisy system. Describing balancing the levels is more than I can do here. There are many good videos about mixer setup on YouTube.com. You cannot "fix" problems created by improper levels and noise injected into the system using the EQ.
What is important is to see that all gain controls and faders are around mid range to 70% when operating normally. You should be using BALANCED lines everywhere possible either XLR or TRS cables. ALL interconnected equipment should be powered from the same receptacle or power source INCLUDING all amps and powered speakers. Often users use unbalanced lines from mixers to sound boards and pick up noise or they have the levels set wrong between the mixer and sound board resulting in clipping and distortion or poor signal-to-noise ratio.

If you are using the factory settings, and you have accidently changed the settings. Look at your manual and it tells you how to get it back to factory settings. If you tweaked the clean channel when you got it, you will have to play around with the settings to get what you want. Hope this is helpful.
