We’d need more specifics about your rig to try to diagnose a problem like that.
I’d make sure your guitar is set up properly prior to going into the preset:
- A poorly cut nut or saddle slot could cause “sitar” kind of ringing from the string resonating on an uneven surface, or
- The nut is cut too low and causing the strings to vibrate against the first fret,
- The truss rod doesn’t have enough relief and the strings are too close to the frets
- The bridge is too low and strings are too close to the frets
- The pickups are too close to the strings and causing the strings vibration to be influenced too strongly by the magnetic field
Possible other factors:
- Your guitar has string length past the scale length break points at the nut and bridge I.e. TOM, Bigsby, Offset vibratos, etc. (Offsets especially are notorious for this but part of their sound imo)
- Springs on a trem vibrating
- High output pickups, high gain, or other sources of high levels of compression could be more likely to pick up small nuances you might not notice in a clean setting
- Harshly put, if your technique sucks this could also cause a similar issue with one of your hands causing some artificial harmonic due to placement.
I’m sure I didn’t hit everything but it’s also a slew of issues that need be to identified as non-problematic before saying it’s the preset, especially without an audio sample or more information on how the overtones occur on the guitar and where it does or does not occur on the guitar.
I had an experience with a Vintera Modified Jag HH where the sound had this odd clicking/clank sound on high gain and I believe it ended up being just the general sound of the guitar with the bridge, humbuckers, and 1 meg pots causing something in the high end to be more pronounced than I was normally used to.
