I found this Realistic Reverb in quite a bad state without a case at a car boot sale, I was intrigued, this is one of those effects that are notorious for all the wrong reasons! Noisy and not really a reverb more of a short delay or flanger (with no modulation.) Once I fixed it up I proceeded to modify a few parts to make it more experimental and push it to its extremes. The slide pots were completely busted so I had to replace them. I adjusted the controls so that at moderate levels it will operate like normal but also can be pushed to the extreme. In this post I will describe how they work and how you can implement these mods yourself.
The face was made by laser printing on Lazertran then wetting , applying then baking in the oven, it creates a very durable graphic. THe DC jack was left in place and is stuck through the enclosure through a square hole.
It is quite simple, locate R21 (on the board it is simply labeled ‘21’) and replace. then replace VR2 the slider with a IMLog one, you can also use 1m linear if you cannot get a Log one. The switches are optional, they are only really necessary if you need to re-house it or if you want to get rid of the phono input on ‘Line.’
It really come alive with no input and just feedback as demonstrated below
