Dr Z AMA: 12ax7s vs EF86

In this week’s Ask Me Anything, Dr Z from Dr Z Amps looks at the difference between the popular 12ax7 preamp tube and the lesser-known EF86 preamp tube.

I’d never heard of the EF86 tube before. They were originally used in microphone preamps, because of their ability to take a large input signal without clipping. Sounds great for pedal players like me.

I’m going to be visiting a few new places over the coming weeks. I’ll keep an eye out for any amps with EF86 preamps, and report back if I find any!
