Sales has sent a K30 jfet my way, which I am waiting to arrive. In the meantime, I have managed to desolder and remove the 2N5457. I then put a 4x1 sip socket in its place and tried out a J113 jfet, which I had as a spare. The pedal worked immediately, albeit with a rather limited range. I hope that with the K30, this range increases. In any case, I'm glad to have found that the issue was indeed with the 2N5457.
As an aside: getting the 2N5457 out was extremely finicky and frustrating, and I found the risk of damaging the board is very high. It may be advisable for anyone building this pedal to use a socket, just in case!
I find it easier to just clip the unwanted transistor, heat up the solder joints, and then just pull the left over transistor legs out one at a time. It's a lot easier to desolder when the eyelets are empty.
