have to agree with all daves comments there, and in particular to the expensive electronic ones, i had trouble with my hilton, ie cheapo sourced power adaptors, why oh why do these electronic companies produce very expensive pieces of equipment, then supply a really naff power adaptor, also i found the hilton, although cleaning up the sound, to my mind, made it too clinical sounding, i sold mine, and went back to my more organic sounding Ernie Ball pot pedal, with input/output jacks on the side, also Goodrich make an excellent pot pedal, i dont know about the telonics, never tried one, but they are mega expensive, these are just my views of course, im sure others will disagree,
ps. why would anyone need a tone control on the volume pedal anyway??? just adjust the amp
