The Hammond 1590J is a wide, deep enclosure: a bigger face than a 1590BB and half again as much depth. It is a less common choice for pedals than the 1590BB family, but the 45 mm of depth takes hardware the flatter formats cannot, and its corners are noticeably squarer than the rest of the 1590 range. Its corner radius of 2 mm is the tightest in the range, so square-cornered boards waste less of its face than in any other Hammond.

How thick are the walls?

The 1590J's walls are 2.3 mm thick. Like every diecast enclosure it also carries a casting draft: each wall leans out by 0.8 mm from the drilled face to the open rim, so the enclosure measures 145 × 95 mm at the rim and 143.4 × 93.4 mm across the face you drill. Worth knowing when a part seats against the inside of a wall, and why a caliper reading depends on where you take it.

What fits inside?

The internal cavity measures 138.9 × 88.9 mm at the face, and the screw bosses in each corner reduce the usable flat area for a circuit board to about 130.9 × 80.9 mm. To check a specific board, put its dimensions into the enclosure comparison tool's fit checker, or place the whole layout in the editor, which knows each component's real footprint and warns when something clashes with a wall or a boss.

1590J drill template

The Stompbox Layout editor has the 1590J as a built-in preset. Place your holes on it, and it prints a true-size PDF drill template with the enclosure outline, every hole position and a ruler to verify your printer's scale. Free, no download, runs in the browser.

Printed at 100% scale it works as a drilling template: tape it to the enclosure, centre punch each mark, then drill. Our guide to hand drilling a pedal enclosure walks the whole job, bit sizes included.

Nothing to tape down, nothing to slip, and it wraps the sides so the jacks line up. The editor makes one from your own layout, for the exact enclosure you picked, $29.

How the 1590J compares

1590J (Hammond) 145 × 95 mm 143.4 × 93.4 mm 45.1 mm 130.9 × 80.9 mm

1590J vs 1590BB

The 1590BB is 26.5 mm narrower, 2 mm shorter and 15.1 mm shallower than the 1590J. The 1590J is the pick when the build needs serious depth; the 1590BB is the standard wide format and sits much lower.

1590J vs 1590XX

The 1590XX is 26 mm taller and 9.9 mm shallower than the 1590J. The two share their width exactly; the XX spends the extra metal on face height, the J on depth.

1590J FAQ

What are the dimensions of a 1590J enclosure?

A Hammond 1590J measures 145 × 95 mm × 45.1 mm externally at the open rim (5.71 × 3.74 in). The drilled face measures 143.4 × 93.4 mm, and the usable flat area inside the walls and corner screw bosses is about 130.9 × 80.9 mm.

How thick are the walls of a 1590J?

The 1590J's walls are 2.3 mm thick, with a casting draft of 0.8 mm per side from the drilled face to the open rim.

Is there a drill template for the 1590J?

Yes. The free Stompbox Layout editor includes the 1590J as a preset and prints a true-size PDF drill template of your layout, with a ruler to verify print scale.
