Mullard 12AX7/ECC83, Matched Pair

Massive tonal difference across the spectrum i also added a mullard 12at7 in v1 and it smoothed out the gain and fixed the harsh bright treble problems i was having with this amp. I mean wow its a completely different amp now im loving this combination i also just decided to grab the matching 12au7 to compare to the original stock setup. Money well spent!

Great little tubes. Plays music nice and mellow without compromising the highs.

Mullards are among the best for creating that good vintage sound. Good value and quick service to get them here early!!

I'm not a guy who chases tone through tube swaps. Until now. What a difference. I put these mullards into my Orange Tiny Terror (all 4 tubes were replaced with mullards). The amp woke up and became something very special. The gain section got way creamier, more violin like. Increased sustain. The grind became fuller and more complex. It's a higher gain amp so my expectations of cleans is pretty low, but even the cleans became fuller and more complex. Worth it. Would do it again, in a minute

These are really good tubes for taming a harsh sounding amp. Ive got these in both a Blackstar HT20 and a Bugera infinium 20. Tames down and smoothes out harsh or fizzy sounding preamp overdrive well. Very happy so far with Mullard tubes, going to stick with this brand for future use.

Good tubes. Made my Bugera v22hd come alive. If you're want a sweet tone, also put in a pair of mullard power tubes as well. I did and love the Bugera now.

I used these tubes in my Marshall JMP1 preamp....and boy they sound good! Smooth, buttery punch on the overdrive channels, and clear on the clean channels. They also solved a hum problem.

Love these tubes, they last and sound great overall. Seller shipped them quickly as well!
