ISP Technologies VECTOR 210 - Manual (Page 2)

Through my years of playing, experimentation and searching for that great
guitar tone, I pioneered the use of the guitar subwoofer. The VECTOR 210
continues that tradition of an active guitar subwoofer designed to enhance
and expand your guitar tone. The VECTOR 210 is designed to be used with
your existing guitar rig with either a line level input or connected to the
speaker output of your guitar amplifier and add that extra impact and huge
bottom end that you can only get by using a subwoofer. Enjoy this new
dimension of your guitar sound.
