ProduktrezensionenElectro-Harmonix 12AX7EH Preamp Vacuum Tube

A good quality 12AX7 tube that is value priced

I was impressed with the performance of these tubes. The 12AX7 has become scarce in the marketplace and when sourced tend to be very expensive. For ordinary audio preamplifiers, these work fine. The brand is not American-made, but seems equal in performance.Vollständige Rezension lesen...

Excellent tube with a slight high end boost !

This is a terrific tube. I have tried many tubes in the past on this guitar pre-amp. This one and others of the same make and specs has a higher power output and more clarity in the highs while keeping a nice but slightly lower mid range. The bass response is just fine though resulting in a nice crisp sound !Vollständige Rezension lesen...

Solid tube

Bought this as a replacement pre-amp tube in my Vox Valvetronix AD100VT-XL amp. Though it's a hybrid amp and not powered by the tube, it plays a big part in the circuitry (namely the gain), tone and overall output. Packs a powerful output while remaining clean and little to no background noise or interference. It is very warm and wide tonally speaking. Before this EH I was using a Mesa Boogie tube and I like this much better. Less bite and gain to the distortion, but you can still crank it and get a wicked good modern rectified sound. Overall very pleased with the performance, sound and quality of this item. Well made. Would buy again.Vollständige Rezension lesen...

Orange micro dark + EH 12ax7= WOW

just installed one as a replacement for a jj tesla.... hfs!!!! it sounds clearer, bell like cleans, louder and thicker when pushed. had to cut my normal gain and volume settings because it was a noticeable difference in volume. if you have a md, install one to receive tonal glory :)Vollständige Rezension lesen...

Super-low noise floor and sounds awesome!

The best tubes for a tube preamp if you want it to have a low noise floor and sound great! I used these in a Bellari RP220 and cannot recommend them highly enough!

Good sounding tubes!

These tubes sound great on my PAS2! Very smooth and no noise whatsoever, and not much more expensive than a random tube buy. Very pleased and would recommend this item.

Great preamp tube

I purchased the E H 12ax7s because they are the least microphonic, an absolute must in a tightly
spaced combo amp. Tone quality is very nice also.

Very nice sounding tube.

I buy this tube for my Hi Fi preamplifier and test them, they sound very good. The sound is open precise and flat but it's not warm like Mullard.
If you like sound less warmer go to Electro Harmonix for warmer sound go to Mullard.Vollständige Rezension lesen...

Tubes I had in my Guitar amplifier no longer worked properly and with new tubes it works great.
