I am hoping that my neighbor can find a use for some of the old classic gear I gave him.
... a stereo compressor (for finish mastering of recorded conglomerate tracks or output to a large "house" system - which means a stadium sized sound re-enforcement system if need be or just your own recordings), a single channel a digital delay with stereo outputs (capable of one one hundredth of a second delay all the way the a full second of delay, rollback, soundover and flanging effects, reverb, slapback, panning and chorus effects from even one note to a stereo output), a pair or single channel notch filters (tunable from fifteen hertz to fifteen kilohertz - one sixth of an octave bandwidth at up to twenty four dB down at the tuning frequency) and an old stereo or three-way crossover (settings from ten Hertz to ten thousand hertz) that will help him get a better sound out of his monitor's sub-woofer system ...
Honestly, I have not used this gear in almost twenty years, but he has a fairly cool little MIDI recording studio set up in his basement. He can get way more use from this gear than I ever will again.
