I have a WD800 and like it quite a bit. Would a Walkabout head give me much different? How would it compare to a D800 or D800+?
If it matters, I use a barefaced Three10T, Audiokinesis Hathor, and Berg HDN212.
I have both and played both extensively both in practices and live.
When the R&D for the WD800 began on TB I was so excited to see what a modern take on my favorite amp would turn out to be. I bought one of the first ones released, I think ser#00053. Naturally upon receipt of the WD800 the direct comparison using the same cabs began...
It's been a while but if my memory serves me, one of the biggest differences I noticed right off the hop was how much more low end was present in the Walkbout at a medium volume. This is at what I would consider reasonably loud controlled drummer jam room type volumes. I mention the volume because one of the characteristics of the Walkabout like it or not is it's tone changes a bit depending on how hard it's driven. To match the sonic signature between the two I was boosting a lot of BASS and setting the parametric to 80 hz and adding a few db on the WD800. I have an some old Mullard tubes in my Walkabout which I believe had an noticeable effect on tone of the amp so YMMV. The harmonics and richness of the Walkabout are unique to it and I can't say the WD800 really nailed that part of the sound.
In all the years I used the Walkabout I always used an Fdeck HPF to control the deep lows. This was one of the asks to agedhorse here on TB when they were researching what players liked and wanted from the new Walkabout. The WD800's damping control is a decent facsimile of what the Walkabout
feels like. It's not the exact same but I appreciate the WD800's option to use it or not. If you like your WD800 always set to "HIGH" damping you may not appreciate the feel of the walkabout. To my ears / fingers, at the volumes I use the Walkabout at, the WD800's damping set to "MED" is closest. With the damping set to "LOW" it's closer to the feel of the Walkabout being pushed hard at less than 4 ohms. My Walkabout was often ran at 2 ohms and it survived although it's not recommended to do so. There's been many threads on operating the WA at 2 ohms and the dangers of doing so here on TB.
The Walkabout is a unique amp and it's faults are part of it's charm. The power curve vs tone response. The HPF is almost non existent meaning there can be a lot of rumble on stages and in the subs off the main pa. The DI sounds really great but it's tied to the master volume so if you need to adjust your stage volume, the DI out knob will need a corresponding blind adjustment or the sound guy will need to do it at the board. There is no pre/post selection on the DI. So depending on the EQing you need for your cabs, the DI signal may be difficult for the sound guy to adapt to correct in his PA system. So if you're planning on using PA support, as many of us need when playing louder gigs with the Walkabout, you may encounter some minor challenges. There is only 1/4" amp outs to the cabs so no Neutrik option. This is where the WD800's design and implementation excel and make it one of the best bass heads available today IMO. My WA has been relegated to my band practice / studio room ever since I got the WD800.
With all its quirks, I still love using the Walkabout every time I plug into it. I've used the walkabout with a lot of different cabs. 410's (MB, Traynor, SWR, Eden, Ampeg, Berg, Epifani) , 212's (Berg, Mesa), 112's (Mesa, Aguilar), 810 (Ampeg, Epifani), 115 (Traynor) and SWR big ben 18. At typical drum levels I've always found a great sound with it. It's a killer amp for recording as well if you can get the fan noise sorted out. There's a bunch of threads on TB about replacing the fan.
I never really got the WD800 to sound quite like my beloved Walkabout so I would say if top volume isn't a need for you, the Walkabout would most certainly provide a different user experience. Weather you like that experience or not is up to you.
