JJ 12AX7 / ECC803S

JJ ECC803S

A premium quality tube that replaces any 12AX7 / ECC83 type. A great choice for combo amps and amp heads!

JJ ELECTRONIC ECC803S: The ECC803S's are great sounding tubes and have a very thick and fat tone with a little more high end than the ECC83S's. The ECC803's are lower in gain by about 10% than the ECC83S's and because of the extremely long plate in the 803S they are more susceptible to mechanical noise and feeding back at high volumes. This is why we do not recommend them or warranty them in small combo amps but they make a great V1 in most all heads where they provide a very thick and rich tone. The ECC803S's also work well in all positions for Fender Heads such as Bandmaster's and Bassman's providing a very vintage type tone
