Maxon FP-777 Flying Pan Phaser/Tremolo Vintage - With Special Made Power Adapter

Description

Up for sale is a vintage Maxon FP-777
Unlike the reissue, which is FET based and sounds nothing like the original, this phaser has optical circuitry and sounds lush and deep, especially when connected in stereo, like it supposed to.
It also has a tremolo section that can be switched separately or together with the phaser.
I also requested from a friend to create a special power adapter which connects to the DIN input (back then, Ibanez had a unique power supply which had a DIN connector) and thus enables you to simply use a regular DC 9V power supply (Negative Polarity) instead of batteries.
Overall the pedal is in very good shape, one thing I need to mention is that the foot switch for the tremolo feels a bit sensitive and might require in the near future some TLC, but that might be expected for a 45 year old pedal.
Will be shipped well packed and with tracking and insurance.
