Hi all
I;m almost new in building pedals for guitar, I've studied electronics almost 30 years ago, so.., I've already built a Rebote 2 but it's not working. I think the problem are the kind of capacitors, I mean after having ordered all the capacitors (I still don't have that nice boxes with all that small drawers filled with caps, res and all the rest, so I need to order them on internet!) I've realized that I've ordered all ceramics capacitors. I've built it anyway but with bad result (read no echo, just clear signal and a lot of noise), so I've changed them with different ones I could take off from old radios, with values as soon as closed to the ones on the schematic, now it works! still not perfectly but I can hear some echo.
So, to make it short, could you suggest which capacitors I have to use and where on the layout, or pls just show me pictures of your own Rebote 2. I've seen some pictures in this forum specially one with some caps in the electrolytic caps' places that look like non-ele caps, so I get almost confused.
I think I did this topic too long, so I thank in advance everybody who can help me.

Ps. Does anybody build a Dyna-Comp from GGG, I've build one but it's not doing what it's supposed to do, may be again caps problem ? do you have pictures also for DynaComp to guide me.

Thanks again,
keep DIYing

i get my caps from www.smallbearelec.com, panasonic film caps or the 'greenie' ones will work for most 1000pF-1uF range.
