The story
I bought it in 2023. I had seen that there were plenty of fans of it, and I wanted to get a taste of it myself and use it in my mixes.
I got it at a bargain price because it was missing its power supply. The peculiarity of the power supply was that it required 9V AC rather than DC. Also, even though it stated that it required 9V, when I found such a power supply (custom), the following happened: When I turned it on, because it was drawing current, the voltage dropped to about 8.2V, and it couldn’t work. The detail was that it required 9V AC when it was connected and powered up (The power supply was “loaded”). That’s why I ordered one from England on eBay from someone who claimed it was specifically for the Alesis QuadraVerb, and when I received it, I found that when the power supply was not connected and powered up, it outputted 10.5V, but when I turned the QuadraVerb on, it dropped to about 9V, which is why it worked correctly.
One problem still remains. When I press buttons or turn the Preset Encoder, it behaves as if I’ve done it multiple times. Instead of, for example, advancing presets one by one, it advances them randomly by 1 or 2 or 3, etc., each time. It seems like it can’t handle what we call “Switch Bounce” in electronics properly. I’ll have to investigate it because it’s hindering my work.
