Alesis dominated the mid-price reverb market in the 1990s with a series of well-designed, low-cost units aimed at musicians and project studios. The Quadraverb is one of their more powerful reverb / effects processors with realtime Midi control of up to six parameters

The Quadraverb has four building blocks that can be used simultaneously: EQ, Pitch Change, Reverb & Delay. These can be used in parallel or serial fashion to create effect chains which can be stored as presets

“So picked up a cheap Quadraverb today locally, because why not? I’m pretty impressed so far. It was made in ’89 and still works perfectly, and the reverb algos are something special, lush in a plastic lofi kind of way. It really does sound like ’90s warp. Extensive midi control as well. Think this thing is going to find a permanent spot behind my MS20”

“Love me some Quadraverb. Playing the resonators is a lot of fun”

“So now the secret is out. Just beware, it’s very much a dated, lofi piece of technology. Don’t expect super lush, analog sounding effects that can compete with plugins. But if you love the reverb, chorus, and flanger type sounds of early Warp records stuff, this is the box”
