i have both the danelectro fab echo & feb chorus pedals
yung fab echo is a very short delay pedal. parang 50 ms max lang (or less). slap back echo ang kayang gawin
very usable tones & quiet in my set up.
3 knobs (mix, speed, at depth) na madaling ayusin to get your desired sound but in a live setting, medyo mahirap magadjust on the fly kasi maliliit ang knobs at opposite ang orientation ng knobs sayo. in short, hindi madaling makita pag nagaadjust
the fab chorus has 2 knobs. you can get also very usable sounds. also quiet in my set up. adjustment on the fly is not so convenient since the orientation of the knobs are the same as in fab echo.
in terms of reliability, gawa sa plastic but if you take care of your gear, they would last.
i would suggest getting a bypass looper para laging naka-on lang yung pedals at yung looper lang ang tatapakan to engage the signal in your chain. at least, hindi kaagad masisira ang pedals
isa pa, this would make your gear in true bypass mode. hindi kasi true bypass ang mga dan electro pedals
fyi
