Another Helix family +1.
my most used board is
Wireless -> HX stomp xl-> line isolator/DI
I also sometimes use the send to my own IEM, and sometimes use the return to receive a monitor mix mixed with my signal
the whole thing is battery powered, which is surprisingly useful.
I also own an HX stomp for an even smaller board, and a helix rack + footboard in my home studio.
I also own 25+ one-off analog and digital pedals I’ve accumulated over the years because I like them, and they certainly have helped me finding sounds that I like, but I hardly ever use them in production contexts at all anymore.
Whether a digital multi can replace a pedalboard for you as a bass player, and which one, depends on your goals/applications.
for me:
-the specific sound I want to hear in my monitors is there, the same, every night
-the specific sound I want to send to the FoH gets sent, the same, every night
-those two sounds can be (and are usually) (very) different
-I never need “that XYZ” - I just need “an XYZ”. I both have the flexibility to design the sounds upfront with that freedom, and the humility to acknowledge the audience will never know or care that the bass player used this particular flanger or chorus or fuzz.
-I never need to design a sound at sound check or mid-show (ie tweak knobs). But I do need two different pre-selected similar sounds in the same family. That’s impractical and flow killing to get from a single pedal with knobs, but trivial with the helix family.
-recording (myself at) practice, rehearsal, and shows is trivially easy
-playing along to stems (and recording it for review, see above) is trivially easy
-MIDI control in/out is trivially easy, especially with the addition of the command center to the stomp line
i have no personal experience with the other big name all-in-one-modelers (kemper, fractal, quad cortex, etc) and have always (perhaps un-informedly) considered the line6 gear more “consumer” than “professional” but honestly it works great and sounds great for me, and the breadth of options for form factor is a real plus.
