Can anyone give me an idea of how loud the Divided by 13 FTR 37 is in half power mode? I have heard many people comment on these being loud amps and some have even gone to the 10/20. For instance, is it really that much louder than say a Deluxe Reverb when in half power mode? I am aware there are many more variables than just the tube compliment in determining an amp's apparent loudness such as speaker efficiency, etc, but I just wanted to see if anyone had any experience in a/b'ing an FTR with more common 2 6v6 amplifiers. This amp just appears to me to be an amp that could do a variety of styles, from country to blues to rock, coupled with the versatility to play different sizes of rooms. therefore, despite the price I feel I could let some other things go; but if the half power mode is more than even a small room could take I would think otherwise. Thanks for any input.
