Unfortunately, there’s no easy way to make the 60’s Tremolo Single work with the Dual Combo Creator as it’s currently designed. I can’t think of any adaptation that would make it compatible either.
To make it work, I’d need to design a separate Dual Combo Creator with a specific 8-pin side or redesign the Tremolo circuit, which would mean losing the pulsing rate LED.
That said, it performs exceptionally well in both the Triple Combo and Singles format.
