The kit arrived in good time and was huge fun to build, with an excellent quality PCB. 

I made one mistake with the placing of the D8 cathode, which stopped the tremolo from functioning; but everything worked perfectly once I'd spotted the error.  All in all, it took about ten hours to build and debug, including a few breaks for tea.

I'm delighted with my Drone Lab V2 and amazed by the range of textures it can produce.  Be warned that playing it can be a hypnotic experience, where hours pass like minutes.
