Cajita Stompboxes is an Argentine effects pedal builder specializing in guitar and bass stompboxes, preamps, DI boxes, and small audio utilities. The shop builds a mix of original designs and recreations of classic circuits, with a catalog that spans bass preamps (BDI.c, BDI.ts, BDI.mini, BD7, 200T), guitar preamps voiced after well-known amplifiers (GT2, FXLR, MESA 59, BRIT30), and a range of dirt and modulation pedals including the Dr Boogie high-gain, Preamp 5150, RAT 6, TS09/TS08, RBmuff/TBmuff fuzzes, Sea Chorus, and Sky.Rev reverb.

The operation is small-batch and hand-built, and is known in the South American gear community for taking custom requests and modifications — switchable controls, alternate voicings, and one-off builds are part of the offering alongside the standard catalog. Cajita also makes utility pieces such as active and passive DI boxes (CA.DI, CP.DI), headphone amps (BDI.hp, PM5, HP6), a piezo preamp, a 3-band EQ, and a compact Class D power amp.

The brand has a DIY-leaning aesthetic — decal-printed enclosures rather than commercial silkscreens — and is generally discussed in Spanish-language forums and Latin American bass and guitar communities, where its preamps and clones are noted for build quality and tonal accuracy at a price point below imported equivalents.

Cajita Stompboxes has 2 products cataloged on Equipboard, including Fuzz Effects Pedals and Delay Effects Pedals.
