Hartke pre amp tube

[LITTLEWING]

Although I haven’t exactly noticed any degradation in the valve sound on my 3500 head, I’m wondering if it’s time to upgrade the tube as it’s done some hours in it’s ten years of life. I sometimes think it’s a little too middly and the other day possibly farted a little using my p bass with custom shop 62’s.

Any recommendations or just don’t fix it if it ain’t broke?

Well, very interesting. So basically valves do one simple job whichever circuit they live in and all we hear in different tones are each manufacturer’s circuit design. Changing valves from any manufacturer does sh*t all and we hear what we want?

I think basically that is the upshot of it. I can’t imagine it will be that different for bass amps. You should watch his one on tonewood as well.
