Fulltone FPS-1 Adaptor
The problem with 99.9% of
all wall-wart adapters is that they are NOT regulated, some straying up
to 13 volts or so, causing Hum and horrible tone. Enter the Fulltone FPS-1
(200 ma.) Regulated adapter....dead quiet, and exactly 9 volts no
matter what your wall AC is putting out. This has the standard 2.1mm x
5.5mm end with a Negative Center Pin and will work with most Boss,
Ibanez, and most other pedals.
FPS-1 (negative
center pin) for use with most pedals including FD2,
OCD, Bassdrive, UltOct, 70pedal, ChoralFlange, etc
