As fetish objects go, guitar pedals are relatively inexpensive. I tend to buy used gear. I thought that making my own pedals would lower costs even further but not really. Unless buying in bulk, high quality capacitors and resistors really add up, no to mention the labor to design the enclosure and assemble. Still, it’s great fun and not bank-breaking, which are reasonable measures of any hobby. And you can save a lot of money over buying rare effect units or those with a long waiting list, like the King of Tone from Analogman.
