Road King loop problem.

[Mesaiolo]

Hello guys,

hope all is well!
I have a question for you, it's all about black magic! :evil:
I just tried to read as many topic as possible, but not found them helpful, so...here is a new one!

I have a Road King, an Eventide Modfactor and a Timefactor.
I have the MF in the series loop and the TF in the parallel.
Everything's ok with the MF in the series loop but not with
TF in the parallel loop.

The problem is this: When the parallel loop mix is between 20% and 80%, and
I switch the loop on, the volume considerable drop and loose punch.
I'll try to be more accurate:

The timefactor is setting with killdry on, and mix is 100% wet.

If I turn the mix knob in the parallel loop to 10% mix I hear the dry
signal and just a little bit of effected signal (and this is ok).

If I turn mix to 90%, I can barely hear the dry signal of the guitar, but
the delay repeats are strong (and this is ok too).

If I turn to 50% mix, I can hear both the dry signal and delay repeats with
equal volume (and this is ok) but the overall volume is dropped!!

Is there something I've missed?? I'm not a beginner, (already had a
triaxis-vht- lone star) but I don't know how to set the mix knob in order
to have a dry and wet signal with equal volume, without volume drops when
switching the loop on!!
The loop itself I think it work nice, cause I tried to put just a cable between the send and the return, and there were no volume issues!

Hope you'll understand and help me out.

Kind regards.

Sounds like the signal coming from the delay is out-of-phase with the dry signal, causing some frequencies (usually in the lows) to cancel out. There are a couple of ways around this...

You could turn the FX Mix on the amp all the way up, disable the killdry on the delay, and use it's mix control to set your delay mix. This should help, although there may still be some phase issues, it wont be as bad.

You could also make a cable to go from the delay's output to the amp's fx return with the polarity on one of the plugs reversed. This will definately work, although reversing the signal wire with the shield might allow the cable to pick up noise and/or hum. If it does, you could try reversing the polarity of the return jack on the amp.

Thanks for the reply!
I don't remember if I've already tried to do as you said in your first hint.

About the second one...if I'll use a stereo cable with two mono plugs maybe I'll avoid the cable to pick up noise/hum.
I mean...using the two signal wire, one as a signal and one as a ground, and reversing them on the plug to put in the loop return. Is that right?

Thank you again for the support.

That should work perfectly. You may need to connect the outer braided shield to ground also, to reject noise...but only on the end that plugs into the amp. At the pedal end, pull the shielding back a little bit and cover it with tape or heat-shrink so it cannot come in contact with the signal wires or the plug body.

Of course! When I'll try it out, I'll let you to know if it works. Thank you so much for being the only one who replied to me.
Thank you again.

Wish you the best.
