Failing Preamp Tube(s) and Noisy Crackle on Mesa Express 5:25

oh finally a mesa that sound like a distorted fender lol

@scarsonmybed Yo dude LOL!!! That's hilarious for real, oh boy! (No sarcasm!)

In the end, I sold this Mesa Express and did not look back. The gain just sounded too fizzy/farty. Just bought a Mesa Mini Rectifier head, not a bad sounding rectifier midget.

@bjornkom My Mesa it's 12" speaker, never had any trouble, if it's not the footswitch that i just can't use because it breaks the sound all the time. Stay Mesa! We are the next midget generation!

yep, just like my fender twin. The crackle isn't as smooth as yours. Mine sounds like someone is frying an egg.

Saw that Mesa video, now replacing the original 12Ax7's with some Russian preamp tubes I have for back-up, thanks!

[bjornkom]

Thanks man, but wouldn't that affect both channels equally?

Could be a bad preamp tube. Start the troubleshooting process.

Search "Mesa Boogie Troubleshooting" on youtube. They have a video up that shows you how to do this.
