Overloading amps input?

I am getting a nasty high end clipping thing going on with my rig. I didn't notice it that much until I had a new pedal arrive yesterday. I thought it was the pedal but then went straight to the amp, and also through a different rig and while not as noticable, it was still there.

Is this because my pickups are too close to the strings? Guitars are LP's with 57's or BB3's. Any other ideas?
 
Input buffer tube may need replacement - it's a preamp tube typically, check it out.

When you say a different rig, is that a different speaker cabinet too?

I tried 3 speaker cabs. So is my thought that my pickups are too close to the strings more than likely not the issue?

I can change that on my tube head but what if one of my other rigs is a SS preamp pedal?
 
I got the same type of noise when I used solid state amps. Nasty buzzy sound right? Like a broken speaker buzz almost? Sometimes I would get a chopping effect if driven even harder past this point and hit with a hard signal. Solid state amps in general must overload easier than tube amps do.
 
Doesn't sound like the pickups to me since neither of those is super high output. A Super Distortion/Invader/X2N/etc would still have far more output than your pups even when they're raised too high. Does it go away if you roll your guitar's volume back a bit?

If I roll the guitar volume back to 7 it goes away.

That doesn't surprise me, if high voltage in a later stage is the problem then less voltage from an earlier stage will ultimately equal less problem. But it doesn't mean there isn't a problem to begin with.

What pedal is the suspected problem?

AMT S1. The thing is, if I go straight into one of my tube amps, I can hear it also. Not nearly as bad and maybe my ears are just listening for it now.
 
So it happens into all rigs with different guitars? Odd. What rig is the SS preamp pedal pushing?

Did you try lowering the pickups a bit to see if that changes anything? Have you tried different cables? Different outlets?

I just spent a few minutes dialing it in at a lower volume again and I was able to get rid of most it. The SS preamp pedal is pushing a Magnum 44 power amp pedal. I tried other cables, not other outlets though. I will get some more volume behind it again tonight and maybe lower the pickups a touch too.

The S1 seems to be rather bright which makes sense I guess. Soldano's can be bright. If I keep the bright switch off on the Magnum and keep the high and mids on the S1 below noon then most of the high harshness goes away. At low volume anyway. I will tweak some more later when I can get some volume going.

I am still open to suggestions.
 
I fooled around with this setup tonight again for a bit and I think I figured it out. I don't know what I did but it is sounding pretty cool now. I am going to make a video review tomorrow night.
