After thinking about it for a long time, I have decided on an amp for which I'll start saving money. The only problem I have is that there are two versions of the amp, the 205C and the 215C. Basically, the 215C has 1 speaker and the 205C has 2 speakers. The 215C features a Celestion G12B speaker and the 205C features a Vintage and a Heritage speaker.

Can anyone tell me what the sonic differences are between the two? The local guitar shops here don't have both in stock, so comparing sound that way isn't an option.
