Handbuilt in the Guptech shop and designed for sonic adventurers, this W.K.B. multi‑effects pedal is a powerhouse modulation suite built into a single box. You get three fully independent effects — each handwired, carefully voiced, and laid out for intuitive stacking.
-
On the right, Widow delivers 8 distinct modulation modes ranging from lush chorusing to warbly tremolo and vibey motion.
-
In the center, KSTR gives you a rock‑solid digital delay, perfect for slapback, ambient layering, or lead repeats.
-
On the left, Berry-Verb serves up 8 reverb modes, from classic spring tanks to massive, haunting ambient spaces.
With its compact footprint and smart internal routing, this pedal makes a full board of time/mod effects possible in one box — perfect for players who want pro‑level tones with boutique sensibility. Built to last, loaded with personality.
