I’m new here and am loving the info and recordings that are being posted.
I have decided recently to step up my guitar and start learning properly, but have been enjoying playing different songs that like for a while now on an acoustic.
Even more recently I have bought an electric guitar (that I am really enjoying) and now a loop pedal and a Boss Katana 50w amp both of which have been great to explore and the Katana has transformed my sound
However, my question is that I seem to have a background hum or hiss when the amp is on any setting other 5an acoustic or clean. The hiss/hum goes away when I touch the strings or jack plug:flushed:. I was wondering if this is normal or if I need to adjust my settings to stop this?
This is common with single coil guitars and it’s the guitar picking up the hum, not the amp. The amp is just amplifying the signal from the guitar. Higher-gain settings will amplify the hum more so the hum is still there on the clean channel, it’s just a lot quieter.
The hum comes from the pickups picking up electrical noise from your environment. This is 50 or 60 Hz (depending on where you live) mains hum and some devices, like fluorescent lights, make this worse.
This phenomenon is the whole reason that “humbucker” pickups exist.
When you touch the strings, your body is grounding the strings which drastically reduces the hum.
Just a quick F.Y.I.
Dowbload Boss Tone Studio from the Boss website.
It’s free and is for the Katana range of amp’s. Just follow install and there are masses of settings to explore if you wish or preset amp tones to download and use through you amp at the click of the mouse.
I have the same amp.
