Electro-Harmonix STEEL LEATHER Attack Expander for Bass Guitar
requires 9volt adapter
The Steel Leather is an expander that operates over a narrow frequency range. The frequency range was chosen specifically to expand the attack portion of a bass guitar’s notes. An expander is a device that makes loud signals louder and quiet signals quieter. An expander is the opposite of a compressor, making your playing more dynamic. The louder your notes the more the Steel Leather will expand or emphasize your attack. On quiet notes, it may not emphasize the attack at all. What this means is that the musician can use the Steel Leather to sharpen the attack on their notes just by simply playing louder. Of course you can also set up the Steel Leather so that it emphasizes every note you play, no matter how quiet the note.
