Got a 4500 like this in Louisville today, $25 + gas money $20 otherwise free delivery. Had to go today, carpet installers come tomorrow. Nice people to haul it 15 miles for me. Came from a neighborhood about 6 blocks from the house of the Steinway. Rode the city bus over with a 4 wheeler on my shoulder and straps and water and a phonebook in my backpack. 4 hours phone call to sitting on my sidewalk. Same music rack as this one. Just read the manual. All that about couplers and pistons and spectrasonic makes me very confused. No volume on pedals except maybe a rumble, low volume on U.M. Didn't try it much at that price. Looks pretty good. Thought I would save the weight, but it has a rotary speaker in it! 390 lb with bench. I think I could get used to having variable length and duration "percussion" on both manuals, but again I thought "multimatic percussion" meant some kind of drum machine until I got it home. Sshhh-Boom sounds as silly as Hammonds H100 brush & cymbal.
