I am an electric guitar player who plays solo blues and jazz. I only use the "Clean" setting on the COSM Amplifier section. I can run any kind of stomp box into this amp with excellent results. The revebr and chorus are very very good. The chorus is so good it has inspired me to write several songs just because the chours sounds so good... but thus, it's a Roland chorus. The delay isn't very useful, but I have a TC Electronic Flashback delay I love, so I don't need the delay. This 50 watt amp is as loud as I need for practicing and for small gigs. It is nice that is has a speaker stand mounting hole on one end. When I bought mine, I bought all the accessories that were out at the time. I got two of the BOSS FS-7 footswitches, and the Roland CB-CS2 carry bag. The amp fits really nice in the carry bag. I already had a speaker stand, but even a very inexpensive speaker stand will work with this amp as it is very light (only 16lbs... its a feather compared to other amps I've had to lug around...). WELL WORTH the price... and... when I got mine the price was higher, so I plan to buy another soon. Kudos to Roland for this particular model. Its been one of my all-time favorite amps. No matter what electric guitar I plug into it, ti sounds great, be it a Les Paul Traditional Pro mII, and Eric Johnson Stratocaster, or even my National Resolectric. The clean channel is to kill for but all the other amp settings on the COSM knob are pretty useless to me. Like I said, I play clean solo blues and jazz, and this works great. It also sounds great with backing tracks. All I need is this one amp and I'm done. Thanks Roland !!!!!
