Elmwood is a Swedish builder of hand-wired tube guitar amplifiers founded in 1998 by Jan Alm in Tannum, Sweden. The company set out to refine classic tube amplifier design with an emphasis on touch sensitivity, channel switching flexibility, and tonal range suited to live performance.

The lineup centers on point-to-point tube heads and combos paired with matching speaker cabinets. Notable models include the two-channel Modena M60 and Modena M90 (the M90 running KT88 power tubes for 90 watts), the lower-wattage Stinger 30, the Bonneville 50, and the 3100, which served as the company's flagship head. Elmwood has also produced effects pedals such as the Woodpecker overdrive/distortion.

Elmwood operates as a small boutique outfit, with each amp built and tested individually. The brand has a following among players seeking a high-end European alternative to traditional British and American tube amp designs, and units regularly appear on the boutique secondary market.

Elmwood has 2 products cataloged on Equipboard, including Guitar Amplifier Heads.
