This Yamaha TA20 Wedge Obelisk Amp is a Innovative Guitar Amp built in Japan in the Mid Sixties. The TA20 is rare and cutting edge in its time. The flexitone rectangular speaker was developed to produce a natural sound from an amplified guitar. They were suited for the voicing of jazz guitars, semi acoustics etc The wedge shape never caught on with conventional pickers but when I tried one recently, I was surprised how loud and punchy it was. Collectors item indeed. $450 OBO email@example.com or text only 250-653-4458 Copy paste the link below to 18 min audio video includes various pedals etc. for a complete audio review of this unit.
