Can someone try this and letting me know what they think. Plug cab in, mute amp, turn amp on, no instrument and check the noise floor increases with the input volume. Several of you are saying the sweet spot is with the input volume around 1 oclock, but with that setting and on idle it is pretty loud. Using berg cab with tweeter at 11ish. I am used to high gain amps that are loud at idle like the M6 and GK MB series.
I'm in..

Gorgeous bass. Daphne/white/maple is one of my favorite combinations for sure. I have a 96 Fender J 5er that's almost there, but the board is rosewood.
Per my PM, checked it, no issue (edit: sent you another PM... I see what you are doing to get that noise... easy to fix and a bit of 'user error' in setting the ratio of the gain and volume.... took me a while to get a feel for it also).
And again, the idea that there is a 'sweet spot' on the input gain and volume will send to totally down the wrong path (although I agree I would not see much need to turn the volume up past about 1 o'clock even with a clean tone goal on the gain setting). That is TOTALLY dependent of the strength of your input signal, how aggressive your technique is, and how much overdrive you want (i.e., the ratio of tube gain to volume). The amp will get 'noisier' if you set the gain super low and the volume super high, but that is user error for the most part. That would be similar to turning the volume down a lot on our bass and turning the gain and master up on a typical amp.
The best rule of thumb to get started is to set the gain and volume at noon, and then as you turn the gain up or down, do the opposite to the volume.
The noise level is on the quiest side with this amp... a bit of the typical hiss coming out of the tweeter as you reall crank the amp, but nothing that could be heard either at low volumes with a piano trio, or moderate or high volumes with a band.
