power adapter noise

the power adapter for the HP4 makes quite a bit of interference - especially with single coil guitars.
Anyone else experience this ? Other than unplugging it, or moving a good distance- any work arounds?

Yes. Looking for modifications to address this. The ilder HP4 units with DC PSU’s didn’t have this issue.
