I think this is more appropriate in Technique as that is
really the crux of the question.
While soloing and getting out there is good, your primary
job is to lock up with the drummer and drive the bus.
I am fortunate that I have a great drummer and we lock up
and sync very well. The sign of the really good rhythm
section is when the guitar player has to do little more than
'frost the cake'. He can not play or just play chords and sing
and it all still grooves.
If you don't have that basic building block in place, then
soloing will become erratic and timing will start to come
apart.
The trick I use when soloing is that no matter where I go, I
am back with a strong emphasis on THE ONE. This anchors
both my groove line and my solo line if I want one - I often
do and am asked to. But having an intimate relationship with
the ONE is key and that means attacking the one with the
drummer until it becomes second nature. Then build from
there.
I'll move it right now for ya.
Edit: Rock Laird held a great anchoring bottom for one of the
most eclectic and innovative fusion bands, Mahavishnu Orchestra.
No small feat that. The Inner Mounting Flame and Birds of Prey are
a testament to how to glue together a band that is way out there.
