P38 "warbling" on G & B strings above the 12 fret
« on: April 07, 2005, 02:38:50 PM »
So I got a Parker P38 a few weeks back. I've noticed that I'm getting some major warbling on the G & B strings when I hold notes from the 12th-21st frets - especially on 15th-18th frets. Argh!

At first I thought it was some digital aliasing problem on my Boss GT8, but the anamoly does NOT occur when I'm playing through my Ibanez AS83 hollowbody. With that guitar, the strings are nice and even across the board. So it appears to be an issue with the Parker guitar and not any of the other gear.

So what could be causing the warbling? It does have a full set of active pickups (HSS & Piezo). I could try dropping the pickup height (they aren't unexpectedly high though) - but what is the ideal height for a Parker P38?

Any thoughts on this problem? What can I do to fix it?

Blessings,

Does the guitar sound OK when it isn't plugged in acoustic sound only? If you can't hear any problem acoustically it shouldn't be physical problem with the guitar and would be confined to the electronics. Are the pickups stock? I have not heard of any active magnetic picks ups in any Parkers.

Yes - acoustically everything sounds fine. No audible warbling. I was guessing from stuff I've read that the magnetics were active. I do not "know"... these are the stock ones - they say "Parker" on them. I can post samples of the sound if needed... :(

Your pickups are not active meaning they don't run a pre-amp of any kind in the guitar. It might have an electonic mixing section with the piezo I don't know on yours I am pretty sure my Fly does. Even if we were to hear it I doubt anybody can diagnose the problem unless they have the guitar in the hands. Keep experimenting let us know what you find something you say might help. Good Luck[:)]

Okay - I lowered the single coil pickup heights to the point that the treble side is almost flush with the body (it was up about 3/16"... I adjusted the bass side so that the angle of the pickup is flush with the neck angle. I set the bridge humbucker up similarly, but not quite as low... about 1/8" on the treble side, bass side set to make pickup angle flush with neck. This was not as easy as it sounds because the body (as you probably know) is arched slightly so that the body angles away from the neck and is farther from the strings/fretboard on the bass side. So the pickups look kinda kaddy-wompus (outta whack)... the bridge looks the same way. Everything looks to be a bit slanted -instead of traditionally flush on a flat top guitar.

If this sounds wrong, by all means tell me! But I can take a pic of what I'm talking about if needed.

The Piezo is active w/preamp and blended with the good old 3-way toggle, etc.

This pickup adjustment eliminated 75-85% of the warble. It is still there slightly on the G string at the 15-18 frets. The other strings seem to have calmed down. Thanks for the suggestion.

I will start a new thread that deals with setting up the Bridge and the individual saddles. There are some clarifications I would like on those areas.
