I love sports. SPORTS.
Question, how often do you need to change the preamp tubes in a hybrid amp like my Terror Bass? How do you know when they're going "bad"? Will they go microphonic and make that same high frequency noise like in a full tube amp? Is it good practice to change them once in awhile?
I'm not having any issues and think mine sounds great, but this crossed my mind the other day. I know there are JJs in there right now, which is probably what I'd buy if I needed new tubes anyways, so I'll probably leave it as is for now. Just curious if I should be keeping an eye on them. I've had the amp for probably over a year now, but who knows how long the tubes were in there before as I bought it used via GC.
