Yes AudioDwebe, I have a GWB35 (one of the recent issues with ebony fingerboard, a replacement for an earlier ebonol one) and the SRF705.
The GWB is easier to play if you want to look at the fingerboard a lot, with the fret lines at the low or high ends of the fingerboard making it more straightforward to see the correct intonation point without allowing for the parallax difficulties of just having the side markers on the SRF. I'm using D'Addario chromes on both basses, and find the basic sound of the GWB more lower-middly than the SRF, although I think part of that is PUP/PUP position. The SRF is more nasal, with a higher middle that's particularly noticeable on the piezo. There's obviously a lot more tonal variation available with the 3 PUPs, I haven't had enough free time with the bass to explore these completely, and have just settled on a few "stock" sounds that suit the kind of work I do (mostly big band with some smaller band and trio/quartet stuff). The people I work with tend to prefer the SRF for most applications, but I find the GWB more punchy, and use that as required.
The SRF is the lighter bass, but both are nicely balanced, although they hang differently. The GWB took some time to play in, but it's singing nicely now. The SRF played brilliantly from day one, and I think still sings better than the GWB.
They work better with different right hand positions, and I love the versatility of the SRF with the possibility of using the high end of the fingerboard as a ramp, then sliding more toward the bridge and playing without a ramp. Lots to explore on this bass, and I'm still scratching the surface after 5 months.
Battery life is much better on the GWB, as you'd expect.
