JFET alternatives for Boss PH-1 Phaser. Can I use any matched quad?

[neiltheseal]

Hello

As the heading says, I was planning on building a Boss PH-1 and wanted to know if they type of JFET was essential.

Aion FX says to use 2SK30A but note that 2n5457 is the same. So could I simply use matched 2n5457s here or even J201s?

Thanks in advance.

2SK30A-GR Is what I used in SMD.

Thanks. I was going to buy SMD jfets and try my hand at matching them myself. I have a whole lot of J201 and 2n5457s. Ideally I would use these rather than buy a batch of 2SK30A-GR in order to get enough that are matched.
