Headfirst v2.1 Zero Loss FX Loops:
Prefer PPFF, but understand if you only want to do G&S.
Long part...
Hey everyone,
Our good friend on here from Hopkins Amplification sent me a ton of PCBs. I was thinking about getting into modding amps for people, but honestly, I just don't have the time. I really just needed this for my 2204, but I decided to grab enough parts to build a handful of these in case others wanted one, too. So up for sale are a handful of these Headfirst FX loops:
https://evolvediy.com/?product=zero-loss-fx-loop-pcb
https://evolvediy.com/?product=zero-loss-fx-loop-populated-and-soldered
These should fit any old school Marshall such as the 1959, 1987, 2203, and 2204. They will also work in any Marshall-style cathode-follower design, but it will be up to you to determine if these will fit your amp or not.
The installation is super easy for a tech and relatively easy if you're new at soldering. Probably the hardest part is drilling the chassis and soldering the input/output to the board. Instructions on installation can be found here:

PCB will include:
BOM and links for where to buy stuff from Mouser
PCB + Parts will include:
Dropping resistors (56k, 47k, 33k, 22k, 10k. NOTE: If your B+ is 280V to 304V, you will need to supply your own 4.7k)
Grounding lug
Fully Assembled kits will include:
Dropping resistors (56k, 47k, 33k, 22k, 10k. NOTE: If your B+ is 280V to 304V, you will need to supply your own 4.7k)
Grounding lug
Wire for B+
Wire for Ground
Shielded Wire for Input/Output (or at least until I run out). Ran out, unfortunately. No more shielded wire left
Overview on installing these in video format:
Overview on installing these on an Origin (PLEASE message me if you want a fully assembled variant for an Origin. It needs to be built with the polarized cap bent and no jacks on the board. It will be up to YOU to figure out how to mount it; I will not drill through the board) :
No warranty on these given the nature of the whole DIY thing. However, if for some reason we determine that the fully assembled ones don't work because of a bad part or bad assembly, I'll refund your money no problem.
Any questions? Ask away! Want to buy more than one? I'll do a discount; just message me.
I promise I'm not really making any money off of these, especially if you factor in shipping and parts. Just trying to pass along a cool deal and help provide cool FX loops to people.
