The JamStands JS-AS100 Amp Stand (often branded under Ultimate Support / JamStands series) is a tilt-back guitar/bass amp stand designed to raise and angle your combo amp or cabinet for better sound projection and stage/studio monitoring.

Key features

• Load capacity: up to 150 lbs (≈68 kg)
• Height range: about 13.25" – 19.75" (336–502 mm)
• Design: sturdy A-frame with locking cross brace
• Tilt-back angle: lets you aim the speaker toward your ears instead of your knees
• Build: foldable steel construction with rubber contact pads for grip

What it’s used for

• Improves on-stage monitoring (you hear yourself more clearly)
• Reduces floor coupling boominess (tightens bass response in many rooms)
• Helps project sound upward instead of straight at the floor
• Makes controls easier to access during playing

Practical notes

• Very stable for typical 1x12, 2x12, and many small 4x10 combos
• Commonly used in rehearsal rooms and small gigs
• It folds flat, so it’s easy to transport

Quick takeaway

This is a no-frills, heavy-duty tilt stand—not fancy, but very reliable. It’s mainly about better sound direction and stage practicality rather than tone “coloring.”
