The cycfi pickups I’m using have nice headers on them, but the power hookups are weirdly at a 2mm spacing. I’m trying to avoid soldering directly to them (though I’ve already done so with one of them) so it’ll be easier to reuse them in different projects, but I don’t have any 2mm female headers and they’re a few weeks away via mail order.

Happily this morning revealed that JST connectors fit snugly on both sides of the pickup and I’ve got the right sizes for both ends! The JST PH connectors fit those 2mm headers perfectly, and the JST XH connectors fit pretty nicely with standard 2.54mm breadboard-sized spacings.

Crimping the connectors isn’t as much of a pain in the butt as I remembered. For sure easier than soldering to headers 2mm spaced apart! This guide helped me remember how – though not before destroying a couple connectors trying to do it from memory.

Two stereo outs, one mixed mono out, and one barrel input for power on the main resonator connecting to two stereo ins and one barrel output for power on the amplifier sidecar routes the channels to the passive attenuators before being mixed into the amplifier… which is stereo. It could be quad with a second board stacked on top, there’s room for the tab breakouts… or it could take a sum from channels 1 and 2 for the left input and a sum from channels 3 and 4 for the right input… or I could treat it like a mono amp, because that’s all it’s driving now…
