Dr. Lake BOSS Hyper BD-2 Mod. / Blues Driver Modify Modification of the BOSS BD-2 by Dr. Lake. An additional switch allows you to switch between two modes. ◆Super Crunch Using rare germanium diodes, this sweet crunch mode offers a slightly reduced distortion, something not achievable with the original BD-2. ◆BD-2 Based on the original BD-2, this mode utilizes luxurious components and circuit improvements, allowing for a significantly enhanced expression of picking nuances compared to the original BD-2. It's a fantastic mode. The Hyper BD-2 mod. was developed and researched with the utmost importance placed on sound thickness and quality improvement. Constructed with carefully selected components, the low frequencies are tightened and the high frequencies are improved for a more crisp sound. This further enhances the original BD-2's characteristics, making it easier to apply picking nuances and control with the guitar volume.
