Every month, we’ll compile a list of announcements, releases and rumors from amp and speaker makers big and small. Here are our favorites from the past month.

Laney Mini Amps

The three-watt Mini and Mini-ST amps can be powered by six AA batteries, and look like miniature versions of the brand’s popular “Ironheart,” “Lionheart” and “SuperG” models.

Laney Ironheart IRT15H

While the original models of the 15-watt, EL84-powered amp head were housed in a metal chassis, the updated IRT15H has been updated with a hardy Tolex cover, sleeker silhouette and devilish new logo.

Hiwatt DR401

The DR401‘s 400 watts and 12 tubes make this bass amp “the most powerful in the world.”

Line 6 Powercab 112 and 112 Plus

The Powercab 112 and 112 Plus are two 250-watt active guitar speaker systems that are capable of replicating six classic, boutique speaker drivers from brands including Celestion, Jensen and Eminence.

Darkglass Electronics Microtubes 900

This 900-watt bass head now comes with a new limited-edition artwork.
