The affordable expression pedal for your Spark Control X
Sonicake
The Sonicake Vexpress is a passive expression pedal that integrates with the Spark Control X through a 10kΩ TRS connection. It requires no power or batteries, which keeps the signal chain clean and reduces setup complexity for mobile rigs. Its compact chassis mirrors the portability of the Spark ecosystem while providing the linear taper necessary for precise parameter control. This combination offers a reliable, budget-friendly way to manage wah and volume without the mechanical dead zones found in competing entry-level gear.
