Product ReviewsElectro-Harmonix 12au7 EH Vacuum Tube

Used in Behringer MIC200

I have owned a few tube amps over the years, Fenders and a 5150 but never moved past 12AX7 tubes because all my stuff sounded great and I didn't put any thought into it.

I bought a Behringer MIC200 pre-amp that I use as a guitar, bass or vocal preamp through an Electro Harmonix 44 Magnum power amp when I need a very small setup. I was always surprised at the good quality of the Behringer, how much use I got out of it, and how huge that tiny setup sounded out of a 4x12. But still I wished the sound was slightly less harsh.

I read a post somewhere in my research that suggested a 12AU7 so I gave it a go. I'll be damned it did exactly what I hoped: soften the attack and brightness a touch without changing what I liked about the preamp. I'm curious what these would do to the sound of my 5150.Read full review...

Good dependable tube.

This ElectroHarmonix tube is an average tube. Not as good as a Tung-Sol or Mullard but much better than Chinese. For the price a good dependable tube.
