Get these tubes!
I have an Egnater Vengeance amp, B52 AT100 amp, and a Peavey JSX. All 3 are really good amps. But I wanted to try and bring out more harmonic content if at all possible. The Eggy and B52 use 6L6 power tubes and the JSX came with EL34's, but it's capable of using 6L6's as well. I did my homework and the SED C sounded like they were very capable of bringing in richer harmonic content. Yes, they are quite pricey for modern tubes, but once I installed them I was pleasantly amazed at how much more tone these tubes can put out. With most modern high gain amps, like the ones I have, most of the tone is generated by the pre tubes as that is how they are designed. Some say that with these modern pre tube tone amps the power tubes don't make much difference. Well, I can easily tell you that that is not true, and I have 3 modern high gain amps to prove it. I've tried the SED tubes in all 3 amps and in each one of them the tone became richer, with greater harmonic content that is very sweet and creamy. I've since sold the B52 amp and just ordered a new Bugera TriRec Infinium. The Infinium circuit is really cool as it will auto bias each tube individually, and that means I can use any tube of different brand and type as long as they fit he 6L6 type socket. The circuit will auto bias each tube! I can run a 6L6, 5881, EL34, or KT88 or any combination of them and the amp will still work. I'll be getting more of these SED C tubes. The bigger cost is worth the money. You'll spend more but you'll also get more. LOVE these tubes!
