Great condition! Made in Japan, and recently imported from Japan! Incredibly rare hall reverb and exciter unit! Phase reverse, mono and stereo inputs, 2 exciter modes, 4 reverb lengths, input and output controls, exciter drive and output control, and reverb and exciter on/off. Runs on normal 9V power. I use on of these with my guitar rig and its a special piece of gear that I'll never sell!!
