Roland AP-7 Jet Phaser - SN 1680 drum but what really floored us

but what really floored us is the sound and how playable the Elka Drummer One is

and Youtube demo below (with thanks to the uploader)

Input is via a single quarter inch input socket on the rear and output is via dual-mono phono sockets

Distortion pedal with a blendable analogue octave up and a booster - for instant earth-shaking Sunn O))) signature tones

however it's in good working order and sounding good following the service: there's not quite as much top end as on a perfect Binson

Roland AP-7 Jet Phaser - SN 1680 drum but what really floored usRoland AP7 Jet Phaser (SN 1680) for sale freshly serviced and ready for studio or stage action. Great sounding pedal. Delivers thick fuzz and swirling phase tones, with ramping speed control between fast and slow (controlled via the right hand footswitch); just like a Leslie speaker. Classic vintage sound used by many legends including Larry Graham. Bold, characterful, and great in the studio or live.
