Amp/Speaker Cases - Tour 4 Series

Grundorf Tour 4™ Series Amp/Speaker cases are all custom built to fit YOUR amp! No more lugging around a manufacturer's "stock" sized case that dwarf's your amp and takes up way too much room in your vehicle!

With a Grundorf case - you don't have to go home and "re-design" the interior of your case. Each case is fully lined with 1" high-density foam to provide a "glove" fit and fully protect your valuable gear. And the best news is, with a Grundorf case, you save money! We don't charge extra for the custom fit!

The Grundorf Tour 4™ Series Amp/Speaker cases are built tough! Each case is constructed with .25" multi layer plywood with a durable ABS laminate finish. The edges are finished with double edged aluminum extrusion. The lid-to-body seal is made with an interlocking aluminum tongue and groove valance system to provide a tight seal. We use 12 rivet point recessed handles to provide the strength needed for years of wear-and-tear. The handles and catches all use a steel washer backed rivet system for greater durability.

You can leave your amp in the bottom tray during use, or set your amp on top of the closed case to get your amp at a height closer to ear level to help control the sound level on stage (and make your sound engineer very happy).

Grundorf Tour 4 Series Amp/Speaker Style Cases feature a lift-off lid design. Each case is custom built to fit each product! Each case comes standard with 1" high-density foam interior, heavy-duty ball corners, four recessed catches (two front and two back), and one recessed handle on each end. Sturdy aluminum extrusion and .25" plywood with ABS laminate are standard on all Tour 4 Series cases.

You may add an optional 3" or 4" caster dolly plate (with or without brakes) to make transporting your gear even easier. Check out all the available options below! You also get to choose a finish color: black, gray, blue, or red.
