Be careful with the rollers, they have a bit of a tendency to stop rotating and you get drag marks instead of stippling. You get the hang of it after a bit and it's not a disaster when it happens. TBH I was quite surprised, given what a clumsy git I am, that it was so easy to get a great finish.
Alto TS308s for monitors and TS408s for FOH. Vocals only, except when one guitarist CBA to bring his cab and I run his pedalboard amp through the PA. Good sound and plenty loud enough, and less than 10kg apiece.
I forgot to mention the rest of the band - as soon as their gear is loaded, they come back to help me (as I'm derigging the PA as well as my own gear, I'm generally ready to load up after they're loaded).
Headpieces don't always reflect neck profile but in this case it very much does. It's not excessively deep but rather full round the sides (Warwick did similar necks after their baseball bat period).
That (as others have said) is the problem. The audio interface side of it will be latency free but anything using MIDI will have a slight delay, which changing ASIO parameters won't alter.
Bass -> multi-FX (or first effect chain) input
multi-FX external loop send (or out of last pedal in first effect chain) to amp input
amp effects loop send to multi-FX loop return (or second effects chain)
multi-FX (or second effects chain) output to the amp return
The first part of the chain precedes the amp tone shaping and anything else in the amp, the second part follows it.
It looks to me like there are two candidates for the black wire (the two that @sandy_r has highlighted) and two candidates for the white wire (the two a couple of cm to the right of the first two). That's going by the relative length and positions of the black and white wires.
