All:

Just got a new SuperSonic 22. Sounds great; no reverb feedback. (If you saw my earlier post, I solved the effects loop problem by just swapping that amp for another one.)

It is a little hissy, though, particularly when you turn on the reverb.

I'm not looking to do major modifications right now, or to bias new power tubes right now.

So, any recommendations for preamp tubes to quiet the hiss down, and maybe lessen the volume on the vintage channel?

Thanks!

If hiss is not coming from your amp's wiring or from electronic accessories from your room like cell phone , computer , halogen lamp .....try some new tubes.

I just bough some Electro Harmonix Gold , 12AU7 and 12AX7 for an Ampeg SVT , They are very quiet .

Some noise ( hiss ? ) may come from unmatched Power Tube too . Close to 8 ma , is a good matched

These amps are known to be a little hissy- I knew when I got it. The hiss increases when I turn the reverb on, so I probably need a new tube there. I don't think it is the wiring, but it might be some of the other things you suggest. Thanks!

Wiring ; it must be a printed circuit , I never work on these amp but some (? ) Fender amps like Hot Rod Deluxe wich printed circuit too , need their few wire to be in the "right " place , if not , you'll ear some noise .

If the amp had never be opened before , wire may be fine , but who know ?
Any mod or repair on amp ?
You write "new amp" ??? New for you or new from the Fender dealer ?

Ok , If you think noise is too loud for a brand new amp , return on waranty . Today's tube are not reliable , maybe some new/ other one could be hisslless ?

There are so many quiet amps why bought a noisy amp ?

Big mistake IMO is never try the amp in the store before bought it .

I like the sound of the amp and the feature set. The noise isn't that bad and I was aware of this going into it. But I know different tubes and maybe a few other things can lessen it, that's all.

If you write a post about hiss , noise may be bad enough to see what you can do when in waranty
