"Seyffert has played bass and sung background vocals with the Akron duo since 2010 to accentuate the band's expanding sound. Here, Seyffert uses his 1959 Danelectro #3923 Doubleneck 6/4 guitar-bass on ""Run Right Back."" He also uses the instrument on ""Same Old Thing"" and switches back and forth between the bass and guitar necks. рI couldnуt afford to take my whole band so I thought a decent solution would be to find a good-sounding doubleneck to play bass lines while I was singing and switch to guitar for the solos. I kept my eyes open for an old Hofner 6/4 я I wasnуt aware of the 3923 Dano until I saw it at a shop on Denmark Street in London,"" says Seyffert."
