I currently play a Dr. Z Z-28 2X10 combo, which pretty much covers all of my gigging needs. I'm looking to replace this amp and pull the trigger on a Divided by 13 JRT/915 and was wondering if this amp will have as much clean headroom and/or will get as loud as the Z-28. Not looking for TONS of headroom, but enough for small to medium-sized clubs. After playing several amps, I've learned that more wattage does not necessarily equal more volume. Even if you haven't played the DR. Z Z-28, any comparisons between the Divided by 13 JRT 9/15 and other tube amps in the 22-30 watt range would be greatly appreciated.
