GAIN: Controls the input sensitivity of the BassKick preamp. Adjust to match your instrument’s output level. Higher gain settings produce punchy rock sounds. MID: Determines to what extent the midrange is boosted or cut. TREBLE: Controls the upper frequencies and subsequently the crispness and overtone content in your bass sound. For a warmer sound, this control is situated right after the input stage in the signal chain. In other words, it also influences preamp saturation. MAINS: AC power swit

-Avoid mechanical shocks and exposure to extreme heat, dust and especially moisture. -When connecting peripheral devices, always heed the proper safety precautions. Never connect speakers with inadequate impedances (ohms), and never connect devices with high output signal levels (e.g. power amps) to your amp’s input. -Ensure you have the correct AC power rating available before you plug in the amp. If in doubt, ask the venue’s sound technician or stage hand. -Refrain from DIY repairs! You should
