This effects pedal features a limiter and EQ, two essential tools for bassists. If you're only going to use one effects pedal for your bass, this type is the one to go for, as it adds both punch and tonal variation. The 5-band equalizer covers bass, low-mid, high-mid, treble, and presence. You might not always need it, but you'll want a limiter for slap bass, and an effective EQ for certain effects. This pedal can fulfill those needs with just one unit. It seems perfect for boosting your sound with a quick stomp during a bass solo, or for highlighting changes in your playing style. I tested it with a 9V battery, and there was no crackling in either the knobs or faders. The warranty from when I bought it used at Ishibashi Music in '97 is still available. I'm also listing other vintage effects pedals and analog synthesizers. Comes with the box and has been lightly cleaned. #effects pedal #equalizer #compressor #bass
