Sluggish cp-70 action
« on: January 05, 2019, 09:06:17 AM »
Hey guys, my cp-70 has one key that's a little on the sticky side. When I took a peak underneath it seems the hammer doesn't return quickly. Any thoughts?

Without being there it's hard to say. Can you take out the action, inspect visually and operate each part manually: wippen, hammer, etc.? Could be a tight center pin, hammer rubbing on its neighbour...

Yes, it could be many things, but likely easy to repair. First thing to look for is usually key bushings that need to be eased, or maybe something (like a penny or a guitar pick) is stuck between the key and a neighbor...
