    Sounds great in my Hughes & Kettner Tubemeister deluxe 40.

    Really nice and "shine" tone. Just take care of the glass size, it may not fit your amp!

    reviewed by: Great tone!

    I had purchased some SovTek milspec tubes for my Manley Stingray HiFi amp and they sounded too bottom-heavy with a roll-off on the highs. I bought these Mullards and they sounded great after just a few hours of burn-in. Much more balanced sound.

    Smooth, well rounded tone. Seems to have less harshness in the highs compared to JJs. Breaks up with pleasing harmonics.

    High end is lush and 3D with great chime, but low end is a bit muddy and undefined when overdriven.

    Didn't like them at first, too smooth, didn't have the clean snap that JJs have in my AC30. Put an EQ pedal in the effects loop as a boost and was surprised at the real nice break up when pushed. Very little of the gak-ak-ak mid range distortion I got with JJ tubes in this amp.

    I bought these to replace some Electro Harmonix tubes in my Peavey Classic 30. Many say to use JJ's and I was considering them. I have them in my Classic 50 head. I'm glad I went with the Mullards.

    Clean, and softer in the tone than the JJ's. At a low volume, the overdrive is not as buzzy/fuzz like.

    I suggest those with the same amp, try these in it.

    I replaced the original chinese tubes with the mullard EL84's and some tungsol 12ax7's that I had and wow! This cheap amp now sounds as good as my Mesa!

    Didn't white enjoou these Valves. My amp did not work really well with them. Had bought 4 matched units and after 4 months a pair Ended up as 2 snow globes. Guess i had bad luck.

    I purchased this tube to replace JJ valves for my Hi-Fi tube amplifier. The sound seems complete - soft, smooth like female voice, and well-balanced.
    It gives better mid/bass volume than the JJ. I think it also produces more vintage like sound than other modern EL84s.
    One of must-have tubes.

    I make and sell valve amps, mostly based around EL84 designs. I have shipped with JJ branded valves since I first began production but I was curious about the new Mullards, so I thought I should check them out. In my single-ended amps the Mullards have a thick mid-heavy tone and a soft early power breakup that is a welcome change from the very up-front JJ EL84 - well worth a try, especially for the blues players. The tradeoff for the added smoothness is a lower perceived volume.
