Danelectro D-5 FAB Chorus Danelectro D-3 FAB Metal Distortion These two items are available at a bargain price. Both have been tested and confirmed to work when connected to an electric guitar and amplifier. They operate with either an AC adapter or a 9V battery. 【FAB Series】 These compact effectors have gained high praise from various sources, despite their unique appearance and affordable price. The form, reminiscent of a vintage supercar, features knobs on the front to prevent changes when the effect is turned ON/OFF. 【D-5 FAB Chorus】 The D-5 [CHORUS] controls the mix with the original sound using the "MIX" knob, the depth and range of the modulation with the "DEPTH" knob, and the speed of the chorus modulation with the "SPEED" knob, allowing for a wide range of effects with their respective balances. At the maximum "DEPTH" and "SPEED" settings, it produces a unique sound, and in normal use, it is a versatile chorus with a vintage feel. 【D-3 FAB Metal Distortion】 The D-3 [METAL DISTORTION] controls the amount of distortion with the "GAIN" knob, the sound quality with the "TONE" knob, and the volume with the "LEVEL" knob. It's a high-gain metal distortion that distorts with a punch. I didn't notice any problems during use, but please understand that these are used items before purchasing.
