Remixing a mixer

Is there a recording musician who hasn't owned a Behringer mixer? They're cheap as chips and do what they say on the tin.

I'm surprised my current model is only the second I've owned in 15 years of mucking about with music gear. It's a tiny thing, but just about perfect for the space I have and inputs I need. That said, it didn't come with an aux send. Those are super-useful, especially with my new spring reverb, so I decided to add one.

A bit of parts diving, soldering, and gluing later and I've got a mono out, stereo return aux bus. Had to scrap the tape I/O but don't think I'll be missing it. Here's a pic of this truly classic Junkbox Raider mod:

I could have made it uglier, but I ran out of time.
