So far so good Nigel. Obviously, I'm not gonna push it volume-wise in rehearsal, and likewise, I'm not putting a whole lot of bottom end stuff through her, but yes it handles both just fine, and as you suspected, I'm using the tape input for the kb, and controlling the level from the kb.
I was really surprised at the output that I could get from this little thing.
Blew my 35 watt Marshall practice amp outta the water.
btw...I've had some necessary work done on 2 of the switches in my Hagstrom II (just some poor soldering) and she's up and running just fine.
I'll try and get some pics of her in use at one of our next gigs, and post them.
