get some right angled plugs & solder the cable.
You can easily turn any standard stereo/TRS cable into a humbuster cable by shorting the ring and sleeve together inside one of the plugs with a small jumper wire. That effectively turns that plug into the TS side of the humbuster cable. Mark it accordingly with tape or paint and use that end on the non-Fractal gear side. The jumper can also be removed to revert the cable back to standard TRS wiring if needed as well.
