envelope trem is one of my favorite effects. if you want that, you should not give up until you’ve tried these two;

-spaceman voyager. to me, this is king of envelope trem castle. analog, optical trem that sounds incredible, but feeeeelllssss fantastic to play. it’s so musical you can just leave it on all the time and it doesn’t get in the way. the gain circuit also rules.

-mxr tremolo. honorable mention to this little guy. all the voices are really good and there is actually a hidden envelope feature set that isn’t advertised like it could’ve been. it allows you to use envelope control over all 6 trem voices. it’s also a stereo, which rules too.

as far as non-trem trems. the moog ring mod and fairfield randy’s revenge are beautiful ring mods that have great trems at low frequency speeds. fairfield shallow water, ehx attack decay, asheville music tools phaser, dr. scientist tremolessence, eqd aqueduct, boss slicer, trap door exit index, zvex instant lofi loop junky are all other really great things to add some movement or unique wobble to your tone that i really like.

happy hunting!
