An outboard preamp designed by SOPHIA bassist Yoshio Kuroyanagi! ASPGEAR is an all-handmade effects pedal from Kobe. This is a popular brand that is supported not only by effect pedal enthusiasts but also by professionals. This model features a modern arrangement of the bass sounds commonly heard in the 1980s and 1990s, allowing for more aggressive sound arrangements. Dedicated circuits are used for the LoM (LOW MID) and HiM (HIGH MID) equalization knobs to prevent interference with each other's frequency bands. Adjusting the HIGH and LOW at the final stage allows for cohesive equalization. This is a classic model as a preamp that can easily add body and body to your bass. Additionally, it features mini toggle switches for BITE SWITCH and LOW CUT SWITCH. The BITE SWITCH changes to a preset EQ for a more aggressive sound. It's a switch that increases the presence of the bass with one action. Turn the LOW CUT SWITCH OFF if the lows are too pronounced. Both can be adjusted with the knobs after setting the EQ, so the LOW CUT SWITCH is particularly convenient for adjustments after the settings have been decided. I think it will be a reliable companion for bassists who play hard. ~KUROYANAGI's VOICE~ When I use 3-4 bass guitars at a live show, a preamp is an absolute necessity for me, but it's much harder than I thought to create a sound that suits my taste and the songs I play while taking advantage of the unique characteristics of each. That's why I asked ASPGEAR to create the TRIBAL AMP! While it has a solid and resilient sound as its foundation, the clear control knobs make it easy to set it up to suit your playing style, whether you're playing with a pick, fingers, or slapping, making it a great product! This is a masterpiece that you'll want not just one for every household, but one for every bass!specification LEVEL HIGH HiM (HIGH MID) LoM (LOW MID) LOW B (BITE SWITH) L (LOW CUT SWITH)
