Some systems run from solar power driven by the store's lighting. The updates are delivered by RF. The display method is incidental, but you're right in saying that obviating any kind of printing yields improvements in accuracy, material and labour costs.
Probably mentioned already, but the lack of a 3.5mm stereo audio in or Bluetooth connectivity for audio is a bit of an omission as far as I'm concerned. Never understood why manufacturers add a headphone jack, but not the means to mix in external sources.
If I can try a bass prior to purchase, I will.
That said, I've bought without trying twice before, once used on here, and once from Bass Direct.
Both instruments are excellent (one Ibanez, one MusicMan)
I'm sure there are companies (or maybe even luthiers) that could fabricate a one-off, bolt-on Bongo neck. Whether or not they've the expertise to lay it up to allow sufficient flexion in the right place/s for the truss rod (if there even is one!) to do it's job is another matter.
Cost? Likely horrific.
Result? Likely rather good. I've a Bongo, and it's quite something already!
I would tend to use HPFs and amp eqs to protect drivers/amps and clean up the on stage/ rehearsal sound.
If I have to use the onboard DI, it'll be pre-EQ if possible.
I favour outboard preamps for instrument tone manipulation, and it's their DI I'd rather send to the desk.
I favour 45-100 anyway, but was pleased when my Bongo turned up wearing 32-45-65-80-100-130.
Perfect.
As you can tell, it's generally my gauge of choice, but fewer manufacturers do the "jybrid" gauge. Most have moved to 45-65-85-105.
