Product Reviews
The JJ ECC803S (long plate.
The JJ ECC803S (long plate. this is the wrong picture) is THE best new manufactured preamp tube available. They perform every bit as well as my late production Sylvania and GE tubes, and who could really ask for more than that. The attack, the detail and resolution which are so obviously absent from most mushy sounding new preamps are all here in the JJ. Overall tone and gain are better than with the more common ECC83 short plate tube and the overall soundstage genuinely compares very well to the old American tubes. This is the the standard that other manufacturers should be following.
I had a regular JJ ECC83 in
I had a regular JJ ECC83 in my bass head that I replaced with the long plate version. There was a noticeable difference in my tone - it was less compressed and there was more headroom. I did not expect to hear such a difference. This is a great tube!
