Holowon Glow Bar


This super responsive analog envelope filter shines as a funk driven beacon in the darkness!

Wah-like filter sweep dynamically controlled by your picking/input signal intensity.

Tube zipper fizz, Q-Tron like Quacks. This little pedal is packed with versatility for your guitar or bass.

The Holowon Glow Bar - the harder you pick the further it sweeps.
