I'm thinking of selling my Modulus Q5 and acquiring an ABZ 5. For you Dingwall owners, how do you think these 2 basses stack up against eachother? How is the string tension different between the two? How are the passive pickups on the ABZ 5?
Please tell me all you love and don't love about the ABZ 5! Need help making a big decision.
Funny thing: I lusted after a Q5 for many years, but that need for clarity and snap has been answered, and more, by my ABZ.
Keep in mind that my experience with the Q5 has been limited to playing them at get-togethers, and noodling on used ones a number of times:
Assuming that your Q5 has a clear-coated CF neck and a fancy quilt top like the ones that I've tried, the ABZ will seem less ornate. However, as you get to know it better, there are a wealth of interesting design touches and ergonomic innovations. Depending on your tastes, the ABZ is either a bit plain, or a study in understated elegance. As mentioned elsewhere in these threads, Sheldon's colour choices are stellar.
The ABZ will also feel noticeably lighter and sleeker. This has as much to do with exceptional balance, as it does with light weight. The thin oil/poly finish is surprisingly protective, yet it feels very organic. You can actually feel the pores in the Ash body, which I really enjoy, but YMMV.
Tension-wise, the ABZ ships with fairly light-gauge stainless strings. I generally used D'Addario EXL170-5SL nickel rounds on my 35" parallel-fret basses, and the first thing that I noticed about the ABZ, was that it didn't have quite the sense of heft under my fingers, that I was used to with conventional 45-130's. I found this quite confusing at first, because the feel under my hands contrasted so strongly with the strong, rich fundamentals when the bass is amplified.
The second thing I noticed, was that the string-to-string tension AND the gauges felt much more even. I never noticed the disproportionate jump to the B string on my parallel-fret basses, until it was gone.
Last and definitely best from my POV, was the articulation on the bottom three strings. If your litmus test for a 5-string is a big, plummy low B, the Dingwall might not satisfy. In my case, my problem was always the opposite- I disliked having to adjust my attack on the B string, and wished for more clarity and pitch definition.
Even when the ABZ is EQ'd for a darker tone, the notes still speak unusually clearly, everywhere from the first fret to the 14th. Especially on the bottom three strings.
The ABZ pickups are definitely one place where you're going to notice a considerable difference. Output level is pretty strong for a passive bass, particularly in the number 3 position (both pickups in series). The natural voicing of the standard ABZ pickups is on the modern side, with a very clear, open top end, and there's something of a growly Jazz/MM thing going on with the tone control wide open.
However, if your Q5 has EMG's, you're going to notice quite a difference in how those highs are delivered. In comparison to the Q5's I've sampled, the ABZ is woodier-sounding and more mid-forward. Also, while there's a lot of treble on tap, there's a definite passive warmth to it. It may have more to do with the attack envelope than the amount of bite, but whatever it is, I used to fight the treble EQ on all my amps when I used EMG's (DC's, CS's or P5's). With the Dingwall, my amps suddenly sound quite sweet up there.
As a life-long P-bass fan, I thought I would probably be pining for Sheldon's extra-cost P-tone pickup, but I've found that the surprisingly effective passive tone control has kept that impulse at bay.
I'll add that a major difference between Dingwall and Modulus, is the level of commitment and interest shown by the manufacturer.
Sheldon is articulate, and always willing to share his thoughts and suggestions regarding setup questions, modifications and future features requests. He is also very quick to volunteer assistance, should there be any perceived problems with his products.
