Brett uses ErgoPlay's Tröster guitar support 

I have been using an ErgoPlay support exclusively since 2005.  These supports enable me to play with both feet on the floor while back and shoulders are relaxed.  The guitar is always secure and the support has never failed during any performance.  All of my students use ErgoPlay.

The "Tröster" rest has two adjustable arms.

• Thigh rest 125mm (self-adhesive hard rubber). Individually adjustable in height and inclination.
• 4 adaptable suction cups for easy rib attachment.
• Suction cups can be changed and removed easily.

• Suitable for tall and very tall guitar players. 

• For playing your guitar in a classic but alternative way.

• For the use of lute, mandolin, bousuki, and similar instruments
