GK rails in a pedal?

Amazing, thanks for the quick reply, I have found some on Mouser (along with the transformer for the TransBoost) so am good to go!!

Cool! Let us know how your pedal builds go.

I don't have a Rails pedal ( I asked John not to send me one, because I didn't want it to influence a design that I am working on:laugh:). But I just love the Transboost pedal that he made for me.

My Rails pedal has been rock solid since its tune-up. It's now the heart of my pedalboard. I never turn it off, and it just sweetens up any dirt I put before it. Just a reminder to try this last in the chain if you stack dirt. This thing can definitely put some beef back into a bright fuzz that cuts, but loses bass. I'll have my first test in the mix Wednesday, but it looks promising so far.

Thanks for the feedback!

Verdict is in - Rails pedal helped pretty much everything cut the mix better. All would have been perfect, but the guitarists kept creeping up the volume. Oh well, it just speaks to the Rails pedal that even at significantly lower volume than the guitars I could still hear myself fairly well. Good stuff!


I keep trying to take it off my main board, I can't. It doe snot sound like any other dirt pedal. It's just different. Can somebody make a version that fits in a 1590a with SMD and a toggle switch for the boost? :)

I'd just love one with standard pedal orientation, maybe top jacks? I'd take muff-sized enclosure and top jacks, too! Basically, the only drawback for me is how wide the dang thing is. It's never leaving the board, it's now my "clean" sound.

Well, 125B with all top jacks would more than work. With two foot switches at the edges, like the Chase Bliss pedals.
 
If you're like me, and don't think of the obvious stuff until much later than you should, here's something to consider if you're using the Rails pedal last in a stacked chain of dirt. Up the "Boost" to cut. I upped mine recently, and I should be able to cut through with just about any fuzz now. The mix will tell on Wednesday, but it certainly seemed like a big difference in ALL my dirt when I upped the boost. Just FYI. Keep rocking!
 
Guys, I'm having a hard time finding the final v5 schematics. The PDF file isn't on johnk site anymore... :(
Am I too late to this party?

Thx!

is this it?

After weeks of being lost in the mix, I tweaked my Rails Pedal again tonight. Found the tone! Just a tiny bit of dirt, but so much more present in the mix than the other times I've used more dirt. Guess I just need to dial it back. Anyway, here are the settings:

Input - Noon
Output - 2:30
Boost - 7:30
No Hi-Cut
Boost engaged

Sounds great, just a bit of dirt. I ran JohnK's Gamma Bass OD in front for more dirt (still not a whole lot, comparatively), and the combo really killed! Guess that JohnK guy knows his stuff...
 
so i was looking over the schematic and the layouts. i noticed the layout for the boost had an extra cap (1uf) that is not present in the schematic for the boost. i assume this is to take the place of the c3 from the drive circuit, right? so the boost circuit is ran in parallel with the jumper in place of c3.

Look at the boost schematic again. C4 on the boost schematic is 1uF.
