When I still built pedals I LOVED Tayda. It allowed me to build between 4 to 6 pedals a month. AND build up stock as well. There's no way I could have done so with using parts from Musikding or Smallbear, let alone that as a European shipping from the US is prohibitively expensive. Really expensive because of the double whammy of both shipping costs and customs duties. Whereas Tayda would 19 times out of 20 sneak under the customs radar if you only ordered enough so they would use the padded envelope. A box, that would get hit, but usually never the envelopes. And I could still built 2 pedals on average on parts with the envelope.
Tayda was an enabler. Allowed me to feed my pedal addiction at a reasonable cost. Wouldn't use them for professional builds for others, but then again I only built for myself. If I still did I would get my pots, switches, resistors, caps, most diodes and the common IC's from them still. And let's not forget their enclosures. Cheapest 125B's I could find at the time, my box of choice. Only the really rare IC's and transistors I would source elsewhere.
