I keep hearing how these are the cat's meow. I've been doing some research into building a bigger rig somewhere down the road and need something that is warm, detailed, articulate, and is capable of doing big sustained low notes for ballads, funkier fingered lines (think donna summers' cut of Macarthur Park Suite), slap lines with authority, and (maybe with the aid of a pedal or something), bordering into a semi-distorted sort of tone for rock. The only amps I've tried that can do this so far are the Fafners, and my SWR working man's 1x10 which is just not going to be loud enough for medium gigs where we're not using a real PA that can handle bass guitar. For those real big shows, I'm thinking of getting together a rack of just real good DI stuff and using the working man as a monitor. Anyway, I've heard the WW amps are phenominal, I'm just not sure that they do exactly what I'm looking for, and I can't try one as I don't have a car and I'm stuck in Rochester, NY.
I've owned two WWs (1200 watt mono and 1000 watt stereo) and they are pretty loud and certainly light but switching power supplies do not deliver good lows, they are more heard than felt. These amps are also anything but warm sounding the reasons for buying a Walter is light weight, high power and tiny size. Think sterile overall, sharpe highs, hollow bellowing, fluffy lows and the smallest amp ever. They are very cool but not the best sounding amp, definetly one of the coolest.
I think you are looing for the Eden tone. You can get a 400 watt Traveler+ head that weighs 13lbs? It has tube preamp tone, and SS power with a toroid tranny. These amps sound great, and warm. I totally believe you need some iron in an amp to get the low end punch. I have the 1000 watt one. I use it for pop, and straight rock. If you need an edge, get the Sansamp Bass river DI to go infront of the amp. I was thinking about a WW, but I heard they were sterile too. A lot of upright guys use them.
I own an older Woods, and don't think it sounds one little bit sterile. It's got the best sounding pre-amp I've ever heard. It sounds warmer to me than my tube preamp (Alembic). With the bass boost on, you'd better believe it delivers the low frequencies. But that's just the ear of this behearer.
I've tried out several WW heads but I've never gigged with one, which is the true test. Alone the ones I've tried did sound bright but this could enable it to cut through that much better. You've described the same sound I've always strived for. If you can find an Amplified Music Products BH-420 amp, jump on it. No distortion but a perfect match for everything else you've mentioned. Dead quiet. They're built like tanks, too... and they're still relatively inexpensive. A possibly underrated 400w @4 ohms in a mid-20 lbs package. I love mine. Still one of the best heads at giving me highly articulate sound without harshness and big controllable lows and mids. For something more current, Ashdown fits the bill. Just for grins I picked up a used MAG 400 and it has the same type of sound though I think the BH may have the edge on "balls". Either gives me amazing full lows that can be expansive or punchy... very responsive. I'm using EA VL110 and Eden D210XLT cabs and the sound of each setup is almost unbelievably good.
To be honest, it's been over a year since I played that set up (Lakland -> Fafner -> EA 2x10s), but I remember thinking I was in tone heaven at the time. It was a really musical sounding rig. For now, I really am oddly happy with the SWR combo, but I think the future could hold either a Fafner, Aguilar, or Ashdown instore and either beargentino or wj cabs.
I'm not sure what I'd want as a big rig. So far the thoughts are the following: Fafner head Ashdown head Alguilar Hybrid head cab possibilities: Alguilar 1x12s (2), Wayne Jones 2x10s (2), Beargentino 2x12
If you plan on getting the Fafner, I'd strongly recommend pairing it with a cabinet that's 4 ohms, NOT 8 ohms.
