good demonstration.So I just did a tube saturation experiment to hear the effect of this chain:
I played the same two-octave scale slow and fast four times while varying the Headway preamp boost level. The available range of boost is from 0 at the lowest setting (7:00) to +32dB at the highest setting (5:00). According to the manual, "Each dot marker equals 2.5dB (approx.) or +/- 40%." The four tests were at:
- Fender American Jazz V, onboard Sadowsky preamp off, no EQ, volume on full -->
- Headway EDB-2 H.E preamp (the dependent variable) with no EQ and with master out @ 3:00 -->
- Noble with no EQ and HPF off --> DI out -->
- Zoom F8 field recorder, normalizing the tracking level in.
Bottom line: I definitely heard a gradual increase of tube saturation at levels 5, 7 and 10. At the highest setting, there was audible hair on the note envelopes. Based on this simple test, if you need audible tube saturation, putting a signal boost in front of the Noble definitely works!
- Dot marker 3 @ 10:00
- Dot marker 5 @ 12:00
- Dot marker 7 @ 2:00
- Dot marker 10 @ 5:00 (max level @ +32dB)
Here's an old shot of my pedal board with the gear described above:

to be clear, I did not mean to suggest that the Noble would not saturate with a hot signal hitting it, but that when I have tried it, I did not care for the results very much. I'm fairly sure that Jacks design goals for the Noble were/are for a pretty clean machine and I have not been able to get mine to saturate in any meaningful/useful way by itself.
I don't want dirt very often, but when I do, I usually get it by pushing a preamp stage AFTER the Noble, like with the Mesa WD800 or Walkabout ... both of which will get pleasantly dirty. For tracking with dirt, I usually use a VST in the box.
Of course, everyone's tone goals are different so it may work out fine for others.
enjoy!
