What is causing odd breakup on a setting that should be clean?

I could use some help, I am running a 2005 American Standard Strat with the lace value pack pickups and a 7 way switch and no-load tone pots, through a Deluxe Reverb RI. About a month ago I decided to switch back to hot rails, and I decided I liked the lace's better. But between then and now, when I strum hard on the lower strings, it starts to break up at really low volumes. The settings are Amp(vol:5 Treb:8 Bass:7-8) Guitar(Vol:3-4 N,M Tone:7 B Tone:7-8) I have a hunch that I overheated the volume pot and messed up some plastic bits, but I don't know if that would cause ugly low volume break up. I have tried 2 other guitars through the amp, a LTD Kh-202 with EMG 81/85, and a RI Coronado with Fender's version of T.V. Jones pups. Both run clean at any volume level with any picking strength.
P.S. I'm using daddario jazz med half-rounds and no pedals
P.P.S To the best of my ears there was no break up before the pickup change and re-change.
P.P.P.S If there is something i'm missing about this, maybe its still the amp. I simply don't know.

Did you change between the pickup types on one control harness or swap complete pickguard and electronics assemblies?

In the case of the former, you may have a soldering error. Equally, you might not have adjusted the Lace pickups to exactly the same distances from the strings as before.

The obvious test for a damaged pot is to temporarily bypass it. Connect one pickup directly to a jack socket. Test this through your amplifier.

I get that sound when the battery dies on an active guitar. Are the Lace's powered? Either that, or as Funk says, a wiring oversight.

Lace's are passive, and I did use the same harness, I adjusted the Lace the the manufacture recommended height before playing, so it must be a soldering error
