BBE Sonic Maximizer 441 (Enhancer) ROLAND DEP-3 (Digital Reverb) This is a listing for the main units only. I am selling these to organize my equipment. Sound output and operation have been confirmed. The enhancer is useful when there is a muddy mid-range that cannot be fully adjusted with an EQ. Turning it on makes the sound clearer. The reverb was used indoors for karaoke. It's convenient because you can control the effect amount for low, mid, and high frequency bands separately. I have confirmed the sound output in all modes, and there are no crackling noises or dropouts. However, please understand that this is a layman's inspection and the equipment is old before purchasing. *No separate sales.*
