The Hammond 1590DD is the widest enclosure in the common pedal range, a long landscape format for builds that spread out: multi-effects, switchers, anything with a row of footswitches. Depth is a moderate 33 mm, in the same class as the 1590BB. Hammond closes it with six lid screws rather than four, so two extra bosses sit midway along the long walls; the what-fits section below covers what that costs.

Drawn from the CAD, so it agrees with the figures below it. Not drawn: the two extra bosses midway along the long walls (this enclosure closes with six screws).

How thick are the walls?

The 1590DD's walls are 2.5 mm thick. Like every diecast enclosure it also carries a casting draft: each wall leans out by 1.2 mm from the drilled face to the open rim, so the enclosure measures 188 × 120 mm at the rim and 185.7 × 117.7 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 180.7 × 112.7 mm at the face, and the screw bosses in each corner reduce the usable flat area for a circuit board to about 171.9 × 103.9 mm. Note that the 1590DD closes with 6 lid screws rather than four, so two more bosses sit midway along the long walls; the usable-area figure counts only the corner bosses. 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.

1590DD drill template

The Stompbox Layout editor has the 1590DD 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.

1590DD vs 1590XX

The 1590XX is 42.3 mm narrower, 1.7 mm taller and 2.2 mm deeper than the 1590DD. Nearly the same face height; the DD adds another 42 mm of width for a longer row of controls.

1590DD vs 1590BB

The 1590BB is 68.8 mm narrower, 26.3 mm shorter and 3 mm shallower than the 1590DD. A 1590DD is roughly a 1590BB and a half in width, in the same class of depth.

Hammond vs the Tayda 1590DD

Tayda's 1590DD-style enclosure is its own casting, not a relabelled Hammond, and we measure both. Across the drilled face it runs +1.6 mm in width and +0.6 mm in height against the Hammond, with 2.2 mm walls (Hammond: 2.5 mm) and 33 mm of depth (Hammond: 33 mm). A drill layout made for one fits the other for ordinary builds; re-check tight clearances near the walls and corners. Both castings are in the comparison tool if you want them drawn to scale.

1590DD FAQ

What are the dimensions of a 1590DD enclosure?

A Hammond 1590DD measures 188 × 120 mm × 33 mm externally at the open rim (7.40 × 4.72 in). The drilled face measures 185.7 × 117.7 mm, and the usable flat area inside the walls and corner screw bosses is about 171.9 × 103.9 mm.

How thick are the walls of a 1590DD?

The 1590DD's walls are 2.5 mm thick, with a casting draft of 1.2 mm per side from the drilled face to the open rim.

Is there a drill template for the 1590DD?

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