The high-quality bass compressor SUMO COMP has been renewed to Ver.2!

Inner Bamboo Bass Instruments is a domestic all-handmade effects brand popular for its high-quality sound. SUMO STOMP is a brand that achieves sound quality and features comparable to high-priced effectors, while also offering compact size, convenience, a luxurious finish compared to its price range, and an affordable price.

This unit inherits the sound of the popular Bass Instruments Ultimate Comp II (U-II) and achieves a more compact size, making it the SUMO COMP.

Controls include Threshold, Ratio, Level, Attack, and Release. It also features a 4/5 sidechain EQ to switch the compression amount for low strings. This is a 4-string/5-string toggle switch that prevents excessive squashing of the low B string and is compatible with high-power active basses. The high frequencies are pleasantly enhanced, the low end remains solid and extends, and while there is a slight fullness, it provides high resolution without compromising the nuances of the original sound. You can enjoy a straight and natural compression.


The previous power specification was 5V with polarity for both positive and negative, but this version uses a 9V specification with a center negative. In addition, the power filter circuit has been strengthened, and the sound has been tuned while reviewing the type of wiring, resulting in a Ver.2 with a rich mid-range and excellent density.

This highly popular model is sure to sell out quickly!
