Just to confuse the issue (only a little):
I have played my WW both as a standalone and as a dedicated bass power amp for 15 years. But mostly the latter.
I use the Alembic F-1X preamp, running its full-range output into a single channel of the WW. Haven't needed to bridge to the 700 watt/8 ohm configuration.
With the WW as a standalone, modern speakers like Edens, Bag Ends and Epifanis seem to work better. But IME and IMO, with this preamp rig you can play many types of music, with a greater choice of speakers.
I play primarily blues, mixing in some funk, swing, jazz, plus Govt Mule-ish heavy rock.
Currently, depending on the gig, I use:
1. one Ampeg Classic SVT-12E; or
2. Mesa-Boogie Powerhouse 2x10 or PH 1x15 (haven't needed 'em together yet!); or
3. Matamp 4x10 [big puppy for outdoor shows].
All cabinets 8 ohms.
Yes, Walter Woods takes great care to design his preamps for tone, flexibility, headroom and low noise, but my "personal hybrid" rig offers greater versatility.
And of course, sometimes the rig sounds better when I bypass the preamp altogether -- it's always an option.
YMMV, etc. Anybody else do this?
