reminds me of a cross between the demeter tremulator and the phasey aspects of dead astronauts tremshifter. has also got the percussive bump of the vox repeater.
i think you've pitched it really well. neatly poised between trem and vibe, adding the opening-up and closing-shut dynamic to the on-off dynamic.
not as slushy and seasicky as a hendrix vibe and not as predictable and one-trick as a regular choppy trem.
