The JamMan drum machine sucks.
In all honesty, the RC20, or RC20XL have better sounding drum tracks, to my ear.
I am curious what the other Jamman owners will say, as maybe they have found something I have missed.
With that said, we are still talking about just a cheese-ee kick/snare thing.
I have an alesis HR-16 that I bought in 1989 that I am still using for a drum machine. I can program it very quickly.
I set the JamMan to the mode where it starts to record as soon as the incoming music starts. so I use my Alesis and guitar.
Again, with that said, I find I also do alot of loop creation from CD's. I like to loop segments of songs, then play along with them.
I have the external foot pedal for the JamMan, and have created 4 loops for Eyes... the Emaj7 intro/outro jam, the Emaj7>Bmin solo, the Emaj7>Bmin>A solo, and the G#m solo.
So using the pedal I can move from segment to segment, and, as it goes with these pedals, solo 'till ya drop.
This method has really solidified my CAGED method of soloing.
I made these loops when I first got the pedal, so they have the cheese-ee drum machine.
I don't think I would ever get into loop-gigging. It's a helluva a practice tool though.
