AC15/AC30 trem equivalent?

[vizcities]

Can my one suggest a trem circuit that's similar to the smooth, harmonically rich one in Vox's AC15 & AC30? I've missed that loping, tubey sound ever since I sold my AC15.

You probably want to look into building the Colorsound Tremolo to get a Vox type tone. If you really want a harmonically rich tremolo, you should also look at the Cardinal Tremolo.
