Critic Reviews

Electro-Harmonix LPB 2ube

soundonsound.com

The Electro-Harmonix LPB-2ube offers a compelling vintage tube sound in an affordable package, making it an excellent choice for DI'ing clean guitar or bass. Its high-voltage all-tube signal path ensures warmth and clarity, and it can add weight to mixes when used subtly. However, the lack of balanced I/O and level metering might deter studio purists. Ideal for those who find software emulations unsatisfying, it excels in delivering genuine tube warmth, though care is needed to manage distortion levels to avoid harshness. Overall, a great addition for musicians seeking authentic tube tone.
