I just bought a 1980's Vintage Roland CK100 (silver one) 3 way speaker keyboard amp, 23 years old, $800.00 new back then 15"/Horn/Tweeter....used it on stage last night & I gotta be honest it sounds better then anything I've used in the past for sure.....it has such a warmth, & wonderful, full robust sound for vocals & keyboard that new Amps cannot compare too, Power is terrific with super coverage & a killer Bottom End being they go down to 38khz ....and I have used many TOTL ones including the Bose Pas, Mackie 450's, Barbetta, Ramsa, JBL, etc, etc, ......Fran has 4 of these units & now I know why....
If I could only find another one to make a pair I'd buy it in a minute NUFF SAID! WOW!
