I picked up a used Roadster head. However, I noticed some strange problems with it.
1) When switching from Channel 2's Brit mode to Channel 1, there is a brief yet noticeable popping/humming noise. This does not occur when switching to other channels or when Brit mode is not selected.
2) Turning up the reverb causes a noticeable hum in Channel 1. This does not occur in any other channel.
The amp still has a few months of warranty left. Should I take it to a tech?
