After reading all the replies in this thread to my inquiry about the 25 vs the 40, I decided to go with the 25, and I'm happy with my decision. It sounds great, and honestly it is still vastly overpowered for what I'm going to be using it for. I have a full sized rig for any other situation, but for home practice, I'll be keeping the volume at 25% max. Also, the tone when set flat is great and the lack of a high mid control is not a problem at all, as I worried it might be. All in all a great practice amp. I heard some bad things about the 15 but for my needs I'm kind of regretting not trying it, because a slightly smaller size would have been nice, and as I said before, loudness is not a concern for me at all.
