I'm gonna build the delay project from tonepad and i want to know what kind of resistors and capacitors to get. I know to get the right values but i mean stuff like

-highest quality
- all the 1% metal film stuff etc confuses me right now

so help me out?
For capacitors, go metal film/MKT for small values to 1uf. Anything larger than 1uf, use electrolytics. For really small values, ceramic caps will be fine but you can use silvered mica if you wish.
For resistors, 1/4w 1% tolerance metal film resistors are perfect. Failing that, you can use 1/2w carbon film resistors but they will be inherently a little bit noisier, but unless you're using values above 1M you will barely notice it.
