hi 62jaguar,
we are the dealer for BYOC, hope the below information help u
1) The kit comes with all the necessary stuff to build the pedal including
- enclosure
- jacks
- electronics components (resistors, transistors etc)
- pcb board
- wires for connection
- switch
2) U need quite some tools if u want to assemble them yourself, such as soldering tool, soldering iron, wire cutter, plier, de-soldering pump, wire stripper etc etc.
These can add up to some cost, so if u are only intending to do it once, u may as well let us assemble for u. If it's a hobby, then it's worth investing in the tools
3) The level of difficulty varies among individuals. Both myself and augus from TYMC are from engineering previously so it was quite ok for us.
The other part besides building the pedal, is painting the pedal. U will need painting or spraying tools to accomplish this.
We provide BYOC kits both unassembled and assembled with paint. We also do mods on BYOC pedals. Hope this will help u, thanks
