Is your Express sensitive?

[leadfootdriver]

That is, sensitive to noise from anything and everything related to electricity.

This amp reveals everything, not to mention the true quality state of your preamp tubes. Tubes that I thought were good, turned out to be a humming, giant glass garbage cans full of scrap metal, busted up sounding mess in this amp.

If the fridge turns on, I can hear it in the amp. If I discharge a little bit of static electricity near the amp, I hear it... If I blow a fart, and it refracts 10 year old radio waves on planet Mars, I can hear it.

I wonder if I should drag around a power conditioner if I play it out somewhere.

I always bring an AC line voltage regulator no matter what amp I use. All my equipment is protected, operating at a known voltage, and the sound is very repeatable from venue to venue.

They're expensive ........ and absolutely essential for sanity at gigs where the stage power is on the same circuit as the air-conditioning, elevator motors, commercial freezers, and ham radio tower and transmitter.
