Replacement shaft for GSP-500 pedalboard

The Ultimate Support MC-05 is a steel shaft made to fit the GSP-500 pedalboard. It provides a stable mounting point for effects pedals during live shows and studio sessions. The tube measures .875 inches across and weighs 2.2 lb. It is sold new for players who need a direct replacement part.

Upgrades from a bent or missing original shaft

If the factory shaft on a GSP-500 is damaged, lost or no longer locks securely, the MC-05 restores the board to its intended height range. The adjustable span runs from 34 to 61 inches, so the swap is worthwhile when the current shaft cannot hold position or has stripped threads. Players with an intact, working shaft gain no benefit from changing it.

Fits the GSP-500 mounting point directly

The shaft mounts straight up or at a 10-degree angle into the existing pedalboard base, requiring no extra brackets or adapters. Its lightweight steel build adds minimal mass to a gig bag while freeing up floor space by keeping the board elevated. Buyers needing a second shaft for a different board model should verify compatibility first.

Questions about this item

What tube diameter does the MC-05 shaft have so it fits the GSP-500 pedalboard?

The replacement shaft uses a 0.875 in (2.22 cm) steel tube that matches the GSP-500 mounting point.

How do you set the 10-degree mounting angle on the MC-05 shaft?

Loosen the angle collar, rotate the shaft to the 10-degree detent, then retighten the collar before locking the height.

When should the steel shaft be inspected or replaced after regular gigging?

Check for tube dents, corrosion or stripped threads every few months; replace the shaft if the 0.875 in tube shows deformation or the height lock no longer holds.
