I built an Aquapuss clone awhile back using the Sabrotone layout and haven't used it much. I plugged it into the loop of my OR15 and it's very weak sounding, the repeats are very quiet. Sounds great up front but it should go in the loop. I also had the same issue with a Reverberation Machine. Any reason why this would be?
Here is the layout:
