- Woody was a respected bass guitarist - he had a large collection of bass guitars (around 450), featured in his own bass instruction video and was held in high esteem for his playing. The Epiphone Rumble Kat signature bass was similar to two specially built double-neck instruments that Gibson made him: a bass/guitar and a bass/mandolin. With the Allman Brothers, although Woody used many different basses, Gibson Thunderbirds were his preferred instruments, along with Alembic Inc basses. With Gov't Mule, Allen usually played the Gibson EB series, particularly the hollow-bodied EB-2 and the solid-bodied EB-3. At times he played a Rickenbacker or Gibson Thunderbird. Ampeg SVT was his amp of choice most of the time. The movie Rising Low, directed by fellow bass player Mike Gordon, is a documentary about bass players dedicated to the memory of Allen Woody and features bass players that he respected and knew in his lifetime.
- Woody was also proficient on acoustic and electric guitar, as well as mandolin, pedal steel guitar, drums, hand drums, & various percussion instruments. Besides his extensive collection of guitars, he collected a vast array of percussion instruments.
