Super-clean example of the classic 18" Portaflex, tons of mojo. Works perfectly. A real low-end champ, well suited for funk, motown, jazz, big band, or any time you need a clean "thump". Great amp for an upright!

Recently serviced, re-capped and re-tubed. Power cord updated to 3-prong, worn speaker cable replaced (still uses a pin connector to connect to original jack in cab). Lucite badge plate customized with the name "George". This vintage thumper is ready to rock, swing, or whatever you're into!
