Hey, Voodoo Labs!

My inquiry today is regarding the ISO 5, and I currently run 2 on my pedalboard. This is my first step in figuring out a problem that arose this weekend. Here's the issue:

After powering up and playing for a while, I noticed my sound cutting in and out. I wasn't the typical sound I would hear when a cable or jack is at fault. This was more of a "pumping" sound. I hit a chord, the volume gradually goes down and then slowly returns to where it started. I did a quick check of connections and even tried a different cable between my guitar and board, but to no avail.

I will be breaking down everything and checking all connections, but wanted to throw out this question:

Could this be power-related?

The reason I suspect power goes back to the unusual way my sound was acting; not crackling or popping, just the strange linear rise and fall of volume.

Any thoughts folks??

Carl

You must have been ripping some mean power chords!! ;)

OK, in all seriousness I'd be very surprised if it was from a power dropout caused by your playing. There is almost no difference in current draw of a pedal when playing vs not playing.
Most likely is that you have a failing cable somewhere or perhaps a failing pedal bypass switch. If it is a repeatable problem, I'd start moving the guitar down the signal chain until the problem stopped. This should give you a clue on where to start looking at least.

Let us know how it goes!

Thanks, John,

A follow up:

-If indeed it's a pedal switch issue, could the signal fluctuate with the pedal disengaged?

Suffice it to say there was not much face melting going on. If anything, I may have shamed my gear into taking a break without me from playing "clams"...

A true bypass switch is always handling some part of the signal path... so yes, a failing one can wreak its havoc in active or bypass.

Were you able to test this setup by moving your guitar down into the next pedal until you either ran out of pedals or found where the problem stops?

Hey, John,

Not yet... unfortunately, I needed to temporarily shift my focus from my pedalboard to my yard. The Pacific WET Northwest is actually getting some sunshine and my lawn is taller than my granddaughter!

I'll keep you posted!!

Thanks for you support.

Oh yea I've been in the same mode... deforesting my yards so I don't lose a toddler in the weeds!
