I posted this in an obscure thread on the double bass side, but it may be interesting to the EB side on using Noble for more than an EB.
The pedalboard idea originally was for blending a double bass mic'd and pickup signals and routing that through Noble. So I tried the EDB-2 H.E and decided to take a simpler route and avoid the challenges of blending pickup and mic. My Ehrlund EAP pickup provides excellent "my bass only louder" (MBOL) amplified sound -- especially when routed through a Noble tube preamp/DI. I've played the Noble almost every day for five years and can't imagine not using it for EB and DB. The Noble adds just 6dB of gain without EQ applied, so another preamp is mandatory for the pickup. I got the Ehrlund preamp from Gollihur Music a few days ago.
I've potentially got a project getting back together that would call for doubling but for now, almost 100% of my playing is creating EB tracks for an independent producer and I can't stand two preamps in the EB chain. So here's what I came up with for a simple, effective solution for optimal sound. A bit bizarre, but it's working out the gate with zero issues.
There are 3 potential chains for this board. Each entails plugging or unplugging a connector or two. The pedal board also lets me avoid hanging anything unnecessary on the double bass. (a quarter inch female jack does hang on the afterlengths to receive a standard mic cable jack)
Double Bass - EAP plus Tube (similar to a mic'd signal)
DB --> Ehrlund EAP --> Ehrlund Preamp --> Radial SB-48UB (48v phantom for the Ehrlund pre; converts signal to balanced AND unbalanced; balanced is available for a clean signal but I don't need it) --> unbalanced signal to Turbo Tuner SB-300 (also a mute switch) --> Noble preamp --> XLR out to Focusrite interface/Zoom F8 recorder/FOH and/or unbalanced out to powered cab/FOH
Electric Bass plus Tube (for practice or gigs)
EB --> Turbo Tuner SB-300 (also a mute switch) --> Noble preamp --> XLR out to Focusrite interface/Zoom F8 recorder/FOH and/or unbalanced out to powered cab/FOH
Electric Bass plus Tube for Tracking (hence the open space in the middle)
EB --> Noble preamp --> XLR out to Focusrite interface/Zoom F8 recorder
