Enclosure choices
Most pedals use Hammond 1590 style enclosures. The most common sizes are 1590B and “125B”. This post is mainly just to summarize datasheets.
Hammond
Here are the Hammond sizes with links to the datasheets. All can be gotten in bare or black. The 1590A, G2, B, and BB are in their “stomp” series, so also available in cobalt, green, gray, orange, purple, red and yellow. Hammond doesn't sell direct, you can get these through distributors like Mouser or Digikey. The 1590G2 is not something I've seen elsewhere and is a really useful size, about half way between a 1590a and a 1590b. The 1590G2 is what Kai Tachibana uses for his compact pedals.
[ETA: Dec 16th, and today I learned there are 1550B and 1550D that are about as wide as a 1590N1, but more similar in length to a 1590B. The Wampler Triumph overdrive might be using a 1550D milled down to 37mm height?)]

|---|---|---|---|
| 1590LB | 51 | 51 | 31 |

| 1590BB | 120 | 94 | 34 |
| 1590BX2 | 254 | 70 | 35 |
Love My Switches
Love My Switches has clones of some of the Hammond enclosures. Their “CNC Pro” are bare aluminum with slightly thinner cases. The regular ones are usually available in black, white, red, and blue.
| model | length | width | height |
|---|---|---|---|
| 1590LB | 50.5 | 50.5 | 31 |
| 1590A | 92.5 | 38.5 | 31 |
| 1590A (CNC Pro) | 93.6 | 38.5 | 32 |
| 1590B | 112 | 61 | 31 |
| 1590B (CNC Pro) | 111.9 | 60.9 | 31.6 |
| 125B | 121 | 66 | 39 |
| 125B (CNC Pro) | 122 | 66.98 | 39.64 |
| 1590BB | 119.5 | 94 | 34 |
| 1590BB (CNC Pro) | 119.5 | 94 | 34 |
Stomp Box Parts
Another big manufacturer in the early 2000s was apparently Mammoth electronics. Mammoth went under in 2019 and sold their remaining inventory to StompBoxParts.com. I don't know if these are the same designs as the Mammoth enclosures, but they are a little bit less rounded/sharper edged than the LoveMySwitches enclosures.
| model | length | width | height |
|---|---|---|---|
| 1590LB | 50.5 | 50.5 | 31 |
| 1590A | 93 | 39 | 31.5 |
| 1590B | 112.2 | 60.7 | 31.1 |
| 125B | 121.3 | 66 | 39.2 |
| 1590BB | 119.1 | 93.6 | 34 |
Bud Industries
Bud Industries has a CU-123 that's the size of a 1590A and a CU-124 that's the size of a 1590B. In their nomenclature, black boxes have a “-B” suffix and gray boxes have a “-G” suffix. (bare aluminum has no suffix). They also still have CU-471 that's about the size of a 1590BB and CU-470 that's about the size of a 1590LB. Bud, like Hammond sells through the big electronics distributors like Mouser and Digikey.
Tayda
Tayda has their own line and also do small batch printing and drilling. [TODO: make a table of sizes and pointers to datasheets]
About the “125B” name
There are several threads on the internet that suggest that the name “125B” comes from Bud Industries. Bud sells a CU-123 that's similar to 1590A and CU-124 that's similar to 1590B, so it's reasonable to assume that they might have once had a CU-125 that's similar to 1590N1. (In Bud Industries naming scheme the suffix “-B” or “-G” refers to the color.)
But user jessenator on PedalPCB gives the following history:
Circuit Specialists (under a different name) back in 1997 commissioned a Korean (or was it Taiwanese ?) company to clone it, sans ribs iirc, as the 03-125B. Which later became cloned and more popularly known as 4S125B made by 4site (not sure if they cloned the 03- model or cloned direct from Hammond) and sold at other places including mammoth electronics (who bought 4site it seems). Then it just got cloned again and shortened to 125B over the years, furthering the cloning of a clone, etc.
