So, being a Greenboy cab guy thus far, I'm curious about your opinion on Greenboy vs. the Barefaced cabs you now have...
I'll chip in on this one. I have about six or more years of experience gigging nEarful 15/6 and 12/6 cabs (built to Greenboy specs by LDS except for the ports, which I asked for round tubes instead of the standard shelf ports), and Fearless 110 and 210 cabs built by Jhawk about 3 or 4 years ago. Last fall I bought a pair of Big Baby 2 cabs, which are closer to the Fearless "tone," which is flat and uncolored.
Bottom line: if you are happy with your Fearless cabs, don't bother buying the BB2 cab because you will not experience a dramatic difference in tone. (Sorry Alex!). I cannot comment on other Barefaced cabs because I haven't played them.
On the other hand, there are significant differences in BB2 specifications that could motivate a switch depending on your requirements.
First up is weight: a BB2 weighs 29 pounds. I've owned many cabs and believe me, 29 pounds is a featherweight for the performance of the BB2! A comparable Fearless 115 (in terms of volume potential) weighs about 43-52 pounds depending on wood type and options. That's a huge difference and is very important to me.
Another reason for the weight difference is construction. The BB2 has a sophisticated internal bracing system that I suppose allows for using less wood. It also dispenses with requiring a mid-range driver, so that saves more weight including a reduced size for the crossover assembly.
Cab design is another factor. I needed to find a different option from Fearless because I adopted a new #1 amp, the Reiner Studio 1200, which is about 12" x 12" and cannot fit safely atop a F110 or F210. Keep in mind, the Fearless wedge design is handy, but in my case it was a detriment. I did not want to move around more weight just for the extra space atop the cab.
The other key difference is the rear panel dial that adjusts output of the BB2's horn. The F110 and F210 also had this dial, but to my ear, there was never a dramatic difference irrespective of where the dial was turned. With the BB2, however, there is a dramatic difference in tone. With the horn on full, the BB2 produces a pristine, PA-type clear tone. Dialed off, the BB2 sounds more vintage in tone. In between is a range of useful, musical options -- especially if you're gigging different kinds of basses such as a Jazz vs. P-bass vs. acoustic bass. The BB2's dial also brings out dramatic differences in strings, such as round wounds vs. flat wounds vs. ground wounds vs. black nylon tapewounds. I've played all of the above through the BB2 and it provides much more granular control over tonal variations using the horn volume dial.
Dave Green's cabs are superb. So are Barefaced cabs. You can't go wrong with either brand. Your selection will be more practical if you focus on specific requirements and match those to the respective cabs' specifications.
