Critic Reviews

Jam Boomster Mk2 Boost | Delicious Audio

delicious-audio.com

The JAM Pedals Boomster mk.2 Boost is a standout in the boost pedal realm, offering a remarkable fidelity and lush tonal quality thanks to its hi-fi-grade Texas Instruments chips. Musicians will appreciate its three versatile voicing options and up to 16dB of clean boost, making it adaptable for various instruments. However, its internal dip switches for bypass selection may not be user-friendly for everyone, and the need for internal adjustments could frustrate those seeking straightforward operation. Overall, while it excels in sound and functionality, the complexity of its features may deter some users.
