This band is a 4pc with gtr, keys, drum & bass, with the main focus on the guitar since Chris Rea was guitarist and front man.
Up to now with this band, (two gigs and a number of rehearsals), i have more or less settled on having both filters at about mid point and no Q, pickup volumes biassed towards the neck, and only changing things for a couple of tracks which have a more bridge pickup bias and a track that sounds like it was recorded on fretless.

I take your point Jimmy and not planning to make bi-amping my norm. I'm just experimenting since i have the opportunity to scratch that itch. 🤣

The sound guy will just have the mono Di feed from my F-1x so the bi amped sound will just be for me to hear. Though i did wonder if this being an outdoor gig will make my hearing of the effect less due to lack of boundry re-inforcement, hence me considering using the 18" speaker cab.

Hey Jazzy, biamping with those cabinets may be a revelation. Letting the 18 handle the bottom octave or so will quite likely be something akin to a religious experience.

The genius of all this was you could just keep cabling, amping and cabbing to wherever you wanted to end up.

F2B, left out to an amp and cabinet, right out to an amp and cabinet.  Not enough?  Just keep jumping amp to amp and add as many cabinets as you need.  Then with a Series 2 bass, set the blend of the two pickups and turn everything up and down via the master volume on the bass.

Or you could repeat the above layout for real bi-amping, not just dual amped as above.  Simply include a crossover'd power amp on each pickup's send (a power amp with a built-in crossover would save time here), and two-way biamp each pickup.  Holy Smoke.

That all this was designed in back in the 70's is amazing.  Today with Class D power, neo-speaker'd cabinets, or IEM's, it may seem like overkill on today's stages, but OMG what this is capable of.

Jazzy the real advantage (if it's worth it) in running each pickup to its own amp/cabinet is that you can tone control each pickup separately.  You'll have to decide if whatever difference you hear vs. summed mono out is worth it to YOU.

Jazzyvee,

I think you can accomplish what you want to do with the crossover in the F-1X.  I have done that before and the results are fantastic!  

i'm quietly confident that bi-amping will not be something i will do as my norm. Most of the gigs i've done with my alembics haven't required much tonal variety so now i'm doing something different musically i just want to take the opportunity this gives me to experiment with my series basses and hear the pros & cons of different ways of achieving tone. This might sound strange but since moving to bass i have not had many gigs where the guitar has been the driver of the sound of the band. As you know most of my gigging has been with reggae bands where chords have tended to be more percussive chops on both guitar and keys ,so now i'm in the thick of sustained chords, alternate tunings, slide guitar, arpeggios and melodies and looking for the best tones to support that. I plan to use my series basses as much as possible with this band. No-one has mentioned anything about what kind of sound they want from me and the only thing mentioned about my basses is the leds. Which i'm taking as a good sign.
Gig is tomorrow. 🥳
