Why was my package refused?
There are a number of reasons your package could be refused by us, including:
I have been playing 35+ yrs, but only relatively recently got heavily into effects. I have tried many, many . . . MANY . . . overdrives, distortions and fuzzes in the past 3-4 years. In general I come to the same conclusion every time. OD and fuzz really aren’t for me. I’m more of a distortion guy. Just a little creamy distortion blended into the top of a clean signal. Just enough to add some grind so you know it’s there. I don’t doom, I don’t stoner, I don’t sludge rock. I mostly worship, country, and blues. So I don’t need anything extreme. Anything more than some subtle grind is just for fun and headphone jamming.
Well, most all of the dirt pedals I’ve tried have left me wanting or just haven’t been for me. I recently totally impulse bought a fuzz just because I could, and though it was fantastic, it also left me wanting for any sort of tone I might actually use in my real world experiences. But it was enough to get me interested in fuzzes again, and I did some research.
20 YouTube videos later, enter the DBMM. I had written off EHX after a few negative experiences with their pedals. I have tried so many "higher end" (ie more expensive) distortions, OD's and fuzzes, that I thought this couldn't possibly compare, given the relatively low price, and it was bound to leave me wanting like the rest of them. But I figured cheap as it was, it was worth a shot.
I gotta say, this is pretty darn good. It’s exactly what I’m looking for. It can do extreme wall of fuzz if I ever want or need that, but the crossover makes it highly versatile. I can dial the sustain back to about 2:30 and add just a bit of grind to the top of my signal. Roll the blend back up and the HPF down just a bit, and it’s a bit more fuzzy. The LPF on the clean blend side helps the two sides to blend together really, really well, as opposed to a full clean blend, which can leave the two signals sounding disjointed (though a full clean blend is still available with this pedal, even if you still use the HPF on the distortion side). And it definitely grinds. With the HPF on the distortion rolled up to about 2:00, it reminds me of that screaming, singing, ringing midrange distortion I got out of the EBS Billy Sheehan Signature. The gate of the DBMM also works swimmingly for killing any noise that might come from the distortion itself, or from my single-coil jazz bass hum. And unlike most other distortion/drive pedals I’ve tried, I don’t feel the need to run this one through an external blend pedal to make it sound good. With the LPF on the clean blend, it sounds fantastic all by itself.
Only two cons so far:
1) It’s a little large for what it does. I suppose that’s justified for the amount of controls you get, but it’s way bigger than I expected it to be.
2) I have zero need for the DI out. That makes no sense to me on this pedal. I cannot see any circumstance under which I would show up at a gig with just this pedal and run a DI out of it to the board. Ever. But maybe somebody would.
