I currently have a Boomerang Plus, a Boss DD-6 and a Gigadelay, a Hardwire DL-8, etc. I also have a modded (R3FX) Line6 DL4. I sometimes work in very quiet, intimate performance situations in which the mechanical click/clunk of a metal foot-switch is noticeable. Is there a digital delay that has quiet/silent foot switches THAT ALSO allows for the use of an expression pedal that can be assigned to control wet/dry mix? The Boss RC-30 has the sort of quiet switches I like, but I do not think it has expression pedal input (as opposed to a tap tempo switch input) (I'm not looking for anything esoteric; the above delays work fine in terms of audio quality for my needs.) In the past I've done things such as using a Boss LS-2 line selector and a volume pedal after it to control, the "return" of my (100 % wet) looped signal, etc. I'm trying to consolidate. Also: Does anyone know if the Digitech Jamman pedals have "loud" foot switches? Thanks.
