Caline CP71 Graphic EQ

You can really fine tune your tone with the CP24 due to the massive range of channels - 31.25Hz, 62.5Hz, 125Hz, 250Hz, 500Hz, 1k Hz, 2k Hz, 4k Hz, 8k Hz and 16k Hz. There's also a gain channel on the left hand side. The CP-24 is silent durable and easy to use. Like all Caline pedals it's True Bypass design, so won't impact your tone when off (although it should be on most of the time). Also works with other instruments.
