So there are differences between the two.

The 1988 has Mid boost instead of Deep, has Skyline tone stack, etc.

This layout here is supposedly the 1984 layout.
I know this is an older thread, but I'm curious if anyone who has built #124 with the original 1984 Classic tone stack configuration shown here could chime in with what they thought about it. Especially if they have built the later Skyliner version and can compare the two.
I ask because I'm working on a #102 high plate Skyliner right now and am considering building #124 alongside it in the low plate Classic configuration to have more variety.
Thanks!

This should provide a solid base. There are also versions on the Ampgarage I did with the parts for a built-in Dumbleator, but to keep things clean, this version is just for the 124 build. BTW, it calls for a 12V transformer for the relays, but in the original 124 HAD used a 6.3V, hence the voltage doubler in the schematic
Small note for anyone using this BOM. The Mid Boost switch (line 134) should actually be an on-on type so it will not be the same switch as the Rock-Jazz.
