The Electro-Harmonix Slammi gives you foot-controlled, smooth pitch shifting up or down by any of the following intervals: half step, Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th & one, two or three octaves!
The MAX BEND thumbwheel control on the side of the pedal lets you select the interval. The BEND push button beside it sets the direction of your pitch shift up or down; if the button is in, the pitch shifts down; if the button is out, the pitch shift up.
The DRY VOL (dry volume) thumbwheel next to the input jack lets you mix the volume of your dry, original pitch signal with the effect signal. If set to zero you will hear only the shifted pitch. If set above zero you will hear the harmonization of your dry signal and shifted signal.
The Slammi operates on a 9 volt battery (included). Plugging into the 1/4 inch input jack activates power from the battery, so you should unplug all cables when the device is not in use to conserve battery. The optional 9V power supply from Electro-Harmonix is 9.6DC-200BI (same as used by Boss® & Ibanez®) 9.6 Volts DC/200mA.
