** Hi,

if you do guitar amp repairs for any time at all, you will likely come across someone like the guy in this Vid:

His Fender Pro 185 ( 150watt rated with 2 x 12inch speakers ) has a small amount of background hum, plus a slight hum in the reverb. But that is NOT how he sees it.

Repairers can be expected to fix faults that develop, but something that has been that way since manufacture is another story - often being near impossible or uneconomic to fix.

The two repairers mentioned wisely chose not to waste time trying.

Well, at least the youtuber didn't trash the two repairers who looked at it.


** He kinda did really - suggesting they must be deaf not to hear the obvious ( to him) humming.

FYI: The Fender Pro 185 has a FET muting circuit which opens when a jack is plugged into the input - that is why he plugged in a lead, fingering the tip to get some hum.

I also wondered for a minute if the power is that room might be missing its earth link.

Anyhow, I posted the vid so folk could observe the typical whiny attitude of these "never happy" kind of guys.

These are the types of guys that would comment on the sound of their band to me at the board. I would usually direct them to an unused channel to adjust. Each time the "adjustment" would make a difference to the sound of the band. pretty amazing for an unconnected channel...
