Electro-Harmonix gives distortion junkies all the gain they can handle without unwanted noise, thanks to a unique spiral filament in the 12AX7ED preamp tube.
This tube from Tung-Sol is a perfect replacement for any 12AU7 or ECC82 circuit. Built to original 6189 specs, it can be useful as a driver or preamp tube.
Don't just replace your tubes. Add a little extra tone and character to your amp with these Mullard Tubes.
