Vox StompLab IIB multi-effects processor designed for bass guitar

Vox StompLab IIB is a compact, budget-friendly multi-effects processor designed specifically for bass guitar.
Part of Vox's popular StompLab series, it packs a robust digital sound engine into a rugged, stage-ready metal chassis. The defining feature of the "IIB" version over the standard "IB" model is its integrated expression pedal, which gives you real-time control over volume and effect parameters like wah.

Simultaneous Use: You can chain and stack up to 8 effects simultaneously (including noise reduction).
Memory: Includes 100 style-based preset programs and 20 blank user slots to save your custom creations.

Features

Genre-Categorized Interface: Rather than forcing you to scroll through confusing technical menus, presets are intuitively organized into ten musical style categories (such as Rock, Funk, Pop, Jazz, and Dance) via a rotatable control knob.
Built-in Utility Tools: It features an onboard automatic chromatic tuner with visual LED indicators. Pressing both foot-switches together mutes or bypasses the signal, allowing you to tune silently on stage.
Portability: Weighing only 780g (1.72 lbs) and measuring roughly 20.7 cm wide, it easily fits into a gig bag or onto a crowded pedalboard alongside existing gear.
