is using a tube amp every day bad?

Tubes will degrade over time but can take a beating. Dont worry about using them every day. Most likely it will take several years before you hear when a tube replacement is needed.

@gnaudio just looking for an opportunity for a juvenile egoistical rant.

Use it once a week then you will have longer tube life.

I use a Twin Reverb daily. Answer to your question: No


In fact, asking this question on a jazz guitar forum would be laughable. 

@pesky_wabbit

well, if it is that nonsensical, why are you here on this forum? why did you even post a response?

I’m guessing you have nothing better to do, and like to cut down on other people that you think are dumb.

If you are going to be a donkey on my threads, stay off of them.
