It's been eight months or so since I purchased a WD–800 amp head, along with a subway 112 cab for my studio, and a 212 for playing gigs.
I'm going to share some of my reactions and experience here in case it's useful to anyone interested in these instruments. I’m referring to them as instruments because they impart a great deal of color and personality to the sound of my basses.
The roots of my electric bass playing extend back to the early 70s, when I was using Acoustic and Kustom solid-state amps. The 80s I had a Yamaha. I considered the default eq of these heads to be pretty flat, with a quick response. I didn't consider these amplifiers to have much character, though, I'm sure that in tandem with their respective speaker cabinets, they likely did.
As someone that has spent a great deal of time doing commercial recording , I've been called on navigate a wide variety of styles. Pop, R&B, Funk, Soul, Fusion, and Jazz are probably my strengths, though, and my default tone would fall somewhere ain there. I'm playing a passive Fender, jazz bass with maple neck, and a fender ultra precision rosewood board.
I'm using a wireless unit from bass to amplifier. These units don't seem to get along with floor pedals. Therefore, I have put my Cali76 Compressor pedal in the effects loop, powered by a Birdsong converter cable in the USB outlet. This compressor handles this well with the input threshold set at approximately 9 o'clock. I'm using it for a mild bit of parallel compression. This is a handy feature to have on an amp head. I've been told that many pedals aren't well-suited to be in effects loops, but fortunately this one appears to be an exception. However, if I was a player that like to do a lot of amplifier EQ changes on the fly, it would upset the gain structure to the pedal.
There is a considerable difference to my ears going from low to high on the damping control. The low setting is much too flabby for my purposes, but I did enjoy spending some time with the middle setting. It creates a rounder sound that I enjoyed when soloed, but for my purposes the high setting was the clear winner. These ported cabinets sound faster and more articulate to me with this setting.
I don't like a boomy sound, and to that end, the high pass filter is a critical feature of this amp. Even in my home studio playing through the 112, I keep this set somewhere between noon and 3 o'clock. Anything less introduces flabby sounds that I'd be unlikely to dial in unless I was playing reggae or something like that. This feature is very useful in live performance as well, with the ability to tame a booming room with a single turn of the knob.
The passive midrange control is unlike anything I've experienced on an amplifier. Apparently, there is some make up volume built into this control, which almost gives the feeling that more than one parameter is being changed as it is adjusted. Having it set at noon seems just about perfect for my jazz bass, leaving in the punch, but stopping short of a cloudiness (to my ears) that happens from 1 o'clock and beyond.
As a matter of fact, noon is where I've landed on most of the settings on this amplifier. A very slight low mid boost and another at 1.3K are all I'm using as my default settings.
Cranking up with a medium loud band in a bar, the amp takes on an additional character. When pumping up the Master volume, there seems to be a built-in compression, so much so that I don't see the need to bring my compressor to the gig (although if I was required to do much slapping I would). I've heard it described as spongy or pillowy, and I'd have to agree. It sort of feels like the notes are bouncing off of a trampoline, if that makes any sense. With the 212, it's plenty loud for any situation, other than a huge club or arena. On an outdoor gig, I found myself backing off of the high pass filter and boosting the bass a bit.
Anyway, those are my impressions of the amp today. I'm well aware that everyone hears things differently, and that my opinions could well change as I spend more time with the amp..
That's it
