I just purchased this amp yesterday from my local mom and pop guitar shop. I bought it at a closeout sale 40% off the street price. Needless to say I couldn't pass it up. I had originally just wanted the 20 watt version but apparently Roland is in the process of updating this line of amps so the shop was unable to order anymore hence the closeout price on the 60 watt model. I haven't really had time to try all the features out but so far I'm very happy with this amp. This has got to be the coolest practice amp I have ever owned. Roland should consider offering this in a head only version say 200-300 watts. That would make a great working bass player live amp. I checked the Roland site and didn't see any indication of just such an amp. Has anyone on the forum heard anything to this effect?
