Thank you for viewing. The following is quoted from the Amazon product page. -------------------- The theme of the BOMBS series is natural sound. It's fully equipped with simple controls that prioritize operability and high-quality parts carefully selected by the manufacturer from audio-grade components. The combination with the highest-grade domestic lead-free silver solder results in a sound reminiscent of a stack amp, with low noise, excellent high-frequency response, and a rich, core sound without sound degradation. Furthermore, the true bypass structure using a 3PDT footswitch minimizes the sound quality degradation, the biggest enemy of compact effectors. Also, the use of a highly visible, ultra-bright LED for the indicator satisfies the player's demands in both sound creation and ease of use. The BOMBS series is a completely point-to-point wired, all-hand-made effector that rivals the price range of two levels above. -------------------- Operation has been confirmed.
