JHS All-American Distortion Pedal Kit

About This Item

    Build your own high quality pedal
  • Genuine JHS circuits and components
  • Easy StewMac instructions and support

All-American: Explosively versatile pedal!
Based on the sought-after ProCo Rat distortion pedal from the 1970s, and favored by greats like Joe Perry, Nels Cline, and David Gilmour.

An unbelievable range of tones, from clean/grit all the way to compressed sustaining fuzz. Makes a 1x12 combo sound like you have a stack of cabs backstage.

    JHS Pedals improved on the original by adding a sweep knob to control the feel of the gain, and a 3-way toggle switch for extra options:
  • LED crunch
  • More subtle silicon grit
  • Raw open clipping
    This is the genuine JHS All-American in kit form
  • Original quality components used by JHS
  • Genuine JHS circuit board
  • Sturdy cast metal case, predrilled
  • Step-by-step picture instructions from StewMac

If you can't buy it, build it!
JHS retired their hand-built All-American, and the only way to buy one has been to talk somebody into selling theirs (not likely). These great pedals need to be back in the hands of players, so StewMac partnered with JHS to create this classic reissue kit.

True bypass: when the All-American is switched off, it does not affect your signal chain.

This DIY pedal kit includes:
Metal pedal enclosure (4-13/16" x 2-5/8" x 1-3/8")
Circuit board
Control knobs
Potentiometers
Toggle switch
Stomp switch
Output jacks
Capacitors
Resistors
Diodes
Transistors
Rectifiers
Op-amp and socket
LED + LED mounting bezel
DC power connector
Ribbon cable and wire

This pedal requires a standard 9V DC center-negative power supply (not included) and consumes less than 100mA. There's no battery option.

Not so easy to assemble

By

Verified Buyer


When I received the kit in France a pot was missing but StewMac was reactive and sent me one immediately. During the assembly I found the pedal not so easy to build. Firstly I had an oscillation issue with the NE5534 when the 100K log drive button was after 12. I made various tests and I found that the capacitor of 100pF was defective. After that when I mounted the kit in the case the 3 position switch broke right away because its lock nut was not high enough. After its replacement, I was able to finish this kit and it works well now. I guess it is better to have solid experience in pedal to build this kit.

Bought on a whim with an order. I also built the bomb boost which i liked. Easy to put together and all, but to my ears this is a fuzzy mess.

Had a few issues.
-The aforementioned error in the instructions, It didn't affect me personally, but they should fix that.
- Poorly marked components. The 100pf cap has no markings. Yes if you view the instrucrions in colour, it matches the instructions, but in black and white? meh. ALSO the LEDs. You are to use 3 red ones in the clipping circuit, but they send modern LEDs that are all clear and unmarked. IF the 3 red ones had been on a strip together I might have been able to tell the difference... so now my clipping circuit is 2 red and one that i think is white.
-MISSING components. I was missing the 2 4001 diodes. I swapped in a set of 4007's from my amp building gear, which I researched should sound similar.


Overall operation. It seems to operate different that the version in the video, the tone control cutting treble as it turns up, THe sweep control doing very little, the 3 way clip selector not having much difference between LED and DIODE clipping Once the tone control is turned anywhere past the first 1/3 it gets muddy sounding, and kind of fuzzy, even with the sweep adjusted and the gain down.

One little Caveat, I have found I was not a fan of the Proco Rat pedals I have tried, but I was hoping the tone control would help, this actually sounded far worse that the proco.

It IS a distortion pedal, and it does work well, with no cut outs or issues, which is why i don't give it "no stars" The tone and the component issues don't make it usable. It will have to sit in the drawer until I get a chance to build something else in the chassis.

Great kit to put together. Yes you have to follow the written directions for the input/output jacks as the pictures are wrong. The board was labeled so you can follow the Tip/Ring to get the jacks installed correctly. Great sound from the pedal as well.

Great pedal kit

The pedal kit was fairly easy to assemble. A vise with non-marring jaws was a big help in holding the board in position during soldering. Make sure to sort all of the components before you begin construction so you know exactly resistors and capacitors values. A magnifier and good light are essential in identifying resistor values. The most critical construction involves the small 3 position switch - it must be square and level or the final assembly cannot be done. I used spray enamel to paint the case. Once dry, I used clear labels for marking the controls and then sprayed clear enamel over everything to seal the labels. The pedal works well and has three distinct distortion settings using the 3 way switch. All in all a very satisfying and useful project.

In my previous review I gave this product 1 star as there was no way i could figure out where i went wrong assembling this device, but the pedal didn't work. Then i read the first review about the directions for the input/output wiring pictures being wrong. Well guess what? I went down, switched the wiring on the jacks, and everything works as advertised. So, I would give the pedal itself 5 stars, and the directions, 1 star. A big thanks to the first reviewer who spotted this issue.

I followed all of the directions, checked my solder joints with a magnifying glass to make sure they were good, fired it up and all I get is a ton of 60 cycle hum and screaming feedback. Re-checked everything again, still no luck. I now own a $115 block of useless junk. Kit is not for the faint of heart. Had previously done projects far more complicated than this without issue.

Response from StewMac


We are sorry to hear you were not satified with this kit. I have sent you an email regarding getting a replacement sent out. Our Tech Department is also available for any troubleshooting you would like to do via the "Contact Us" link on our website. - Spencer, Customer Support

Easy to build and great sound

By

The pedal went together easy with two small snags.

1: when adding the power leads to the main board, do it before you mount the pots, there is very little room afterwards.

2: the text describing how to solder the signal leads to input and output jacks is correct, but the picture is backwards. Follow the text and skip the picture.

This pedal sounds great and was fun to assemble.
