"WOW...."

I have a Carvin x100b tube half stack. I replaced the tubes with these and also 4 same brand EL34. All I can say is wow. My amp is so clear and loud. I mean in the house I can only go up to 2 and it is loud. Treble end is crystal clear and the bass end is nice and crisp and well pronounced.... Mid range is strong and clear as a bell.... I will buy them again when I need tubes again.

Musical Background:

Playing for 40 years

"Poor Packing"

Overall: 1 out of 5 stars

Love these tubes but zZounds did the absolute worst packing job. The box it shipped in was only half full of paper leaving the tube bouncing around during shipping! The tube itself was noisy and couldn't use it for V1 which is what I was looking for. I now have a beat up paper weight.
