Without knowing your complete setup it is hard to know the source of the problem... HOWEVER... One problem I see is that if you are using certain types of external effects, this device does NOT use balanced lines (TRS cables) and some of the effects units do use balanced. That, depending on your cables can cost 6DB of gain... and MAY be intermitent depending on whether your cables contact the ring of the TRS connector in the effects unit. This is not normally a problem if you are only using pedal type effects units. Most rack mounted effects are another story. If you need to go between balanaced and unbalanced you may need to use DI boxes. Since this device uses relays, if a relay isn't conducting fully it would distort the sound terribly passing mostly high frequencies.
Hi there,I have the same problem with my flexwave 120. I opened the amp to measure several capacitors on the small effect circuit board. If one of this capaciters have internal short circuit, wich will effect the others causing effects to fail. I removed them one by one to find possible short circuit. All capacitors were ok. I think the problem is in the processor wich is to diffucult to replace. I think it's easier to replace the effects circuit board. But where do we find this board??
A lot of the effects chips run off of the +5 volt or +3.3 volt power source while a lot of the audio is off +/-12 or 15 volts. Sometimes loss of the +5 causes loss of the effects. Check that before assuming a chip is gone.
This is a wild guess, but I have had a different model, a 110, that had a bad electrolytic power filter cap on the effects board that while a meter showed 5 volts for the effects, what was happening is there was dips in the unregulated voltage that fell below what the regulator needed and the voltage to the DSP fell to the point that the DSP was resetting at twice line frequency. This was ONLY visible using an oscilloscope. ALWAYS verify your power supplies with an oscilloscope to look for ripple and noise. With the processor continually reset, the unit appeared to be inoperative.
The effect loop is to use exteernal effect module... It is NOT to use guitar pedals !!!! The signals are line levels, NOT guitar type levels. An example of a device might be an Alesis Quadraverb. You take the effect send jack and run it into the inout of the effects module and the output of the effects module into the effects return jack. Many try to use guitar pedals and massive distortion results because levels are too high for the pedals.
Distortion is a very HIGH gain operation and any hum on the input will be amplified many times.
Check your guitar AND input cable for ANY hum at all at high gain settings on the amp WITHOUT the pedal in line to assure that the source is not before the pedal.
ADDITIONAL cause could be a poor power adapter for the pedal or even a bad filter cap in the pedal.
I repaired a Behringer guitar amp that had a DSP effects in it (BX1200 I believe).
The effects were on a seperate board and the board had its own 5 volt power supply. The filter capacitor for the 5 volt power on the board was UNDERSIZED and it had degraded causing the 5 volts to drop out of regulation, dipping to 4 volts. This caused the DSP effects to fail.
YOUR device MAY use the same DSP OR design.
Check the 5 volt power with an OSCILLOSCOPE to look for dips below the 5 volt operating point that occur at 120 HZ.
