That 230 is one of my all time favorite analog delays. I had one for a while and regretfully sold it because I never thought I would have a studio to use it in. Silly silly me. I wish I could find one again, but they seem to be very overpriced for what I want as an analog delay. I seem to remember as far as sound goes, one of the thickest HEAVIEST delays I have heard. Really nice modulation on it. A little noisy, but they all seem to be to some extent. I thought one of the coolest things about it was the LED input and output meters. Big blinking lights are yummy.
