Hey, I recently was given an old ARTVERB effects rack. WhenI use it, the low notes get muddied up. I was wondering if there is an inexpensive way to filter the effects so the lows are clean and the highs are wet. I have a G-K 800rb head that has a crossover (I don't know if that would work or not). I was thinking that perhaps an EQ on the rack in the effects loop might work. Any advice or experiences that you could offer me would be appreciated! Thanks.
