Does the mythic quest for Dumble-style tones culminate in this boutique box?

The mythology that surrounds Alexander Dumble’s creations has led to an entire cottage industry of builders trying to replicate that sound, but without the five-figure price tag. Vertex Effects’ take on a Dumble Steel String Singer is billed as a “clean drive,” but I found the latter descriptor to be more apt. In addition to the volume and gain controls, there’s a filter knob that helps to focus the midrange.

I was quite surprised with how much gain the SS could churn out. In front of a clean amp, the pedal got very growly and, at times, heavy on the low end. Even with rather bright T-style pickups, I found myself fiddling with the filter control to help clear up some muddiness. The volume knob tended to really bring the best out when pushed past noon. The thick D-style feel and warm, smooth compression was there, but I think it really shined in rougher, grittier tones—with the gain knob at least at 2 o'clock. If your tastes are more Texas Flood than In Step, then the SS might be the best way to save $90,000 on your rig for the next blues jam.

Pros:
More versatile than I expected. Nice amount of gain.
