I ran into an odd problem. After great experiences with the Walrus Audio Ages, Eras, and Eons, I purchased an Iron Horse V3. After plugging it in, I observed a gated effect due to my guitars’ EMG pickups overloading it. This would happen when pedal gain was at 60% or higher. When I turned guitar volume down about 50%, the issue went away.
I sent the pedal to Walrus, who tested it, heard the same thing with an active-loaded guitar, said it was functioning as designed, and the overloading is normal for active pickups.
So…now I’m wondering if having a buffer between the guitar(s) and Iron Horse will reduce the EMG voltage and help with giving the pedal enough headroom to use more of its gain range.
Passive pickups have a typical voltage peak of 0.5V. EMGs peak at about 1.75V. Anyone know what typical peak voltage is for a buffer?
All I’m able to find online is output impedance for buffers, and no info on their output voltage. Thanks!
