Apparently the low output is “by design” as the Benjolin was originally designed to be standalone, so the final filter outputs were meant to be closer to line level than modular level. I found this out when trying to plug mine into the Twinpeak filter and noticing that output was very low. (Todd Barton shared that little tidbit with me - I bought my Benjolin from him and had mentioned the low output to him.)
I did the mod posted over at MW and it did bring up the output quite a bit. It may have added a touch of distortion, but I haven’t really noticed it. It’s also really easy to undo later if I needed to.
One of the base patches I use for the Benjolin is to have the pulse outoput of Osc 2 pinging the filters on the Twinpeak on Input 1, with the Runger going to V/oct input on the filter. Then the filter output of the Benjolin goes to Input 2 of the Twinpeak. Good times.
