The Jamman Stereo is a robust piece of kit, with space for upto 99 loops, of upto around 10 minutes duration, with the onboard memory, expandable with COTS memory cards.
It's easy to use and get looping. Overdubbing is simple, and the auto quantise is a useful function.
2 minor gripes - I can't dial in the tempo, I have to punch it in. It would've been nice to be able to dial in 120 bpm at the flick of a dial
There's no midi.
Again, it's not as if these features were hidden, more expensive kit may feature these as standard so well worth factoring in, if these are essential to your requirements.
The Andertons service was excellent. It was reportedly the last item in stock. I phoned in to make sure they had it, and when informed it was the demonstration model, they phoned my back later to confirm that I still wanted it, as they said there was some small cosmetic damage.
I've yet to find the damage, and they rather obligingly sent me a spare guitar cable gratis. The goods arrived promptly within the agreed timeframe (next day).
Well done guys :)
