So I'll be jamming these in the mail tomorrow (still hoping practice happens tonight, as it fell through last week), but I have had some time with these in the shop with the Quad Reverb which gives me a decent impression at volume.
I'd like to shout a round of thanks to IdiotBox, to Chankgeez for doing excellent logistics work on this, and ILF in general - the community that can pull something like this off is magnificent and I'm happy to be a part.
This experience has really put into sharp relief the concept of builder's ear for me. To put forth an analogy - (and forgive the comparison to my own builds, but it was bound to happen and I'll get it out of the way as fast as possible and remain as unbiased as I can) let's say guitar tone is a medieval battle: there's going to be punishing levels of blood and guts everywhere, things are grisly in both the moment, and the long run; and finally, stamina is really going to be a deciding factor here.
My immediate take away from spending (an admittedly short) time with the tourbox, IdiotBox has a firm clarity angle, cutting, in a sense. With the IdiotBox stuff I hear swords clanging together, the impacts and subsequent removal of small bits of leather armour (some still containing bone), chain mail, and ultimately flesh. It's a very high contrast environment for me and to be honest, not entirely my comfort zone. With RMA, I seek the rush of blood to the ears, and your war scream, letting the external action take a lower tier. The clarity and edge these works imbue on my playing are therefore outside my personal reference, so it's somewhat difficult for me to unabashedly gush - but I want to be clear that I do indeed dig the lot.
It seems like a clumsy analogy to me (not enough beer at the time of writing) but it's the closest definition of my impression I can muster.
Here's an explanation of what is going on in the following pictures: process involves a sine wave signal source to create a signal, an HP330D distortion analyzer, and an oscilloscope set to XY (this is where one channel drives horizontal deflection and the other drives the vertical). The distortion analyzer is essentially a notch filter feeding a voltmeter, and setting it up involves aligning the notch filter to the exact frequency of the sine generator (so it eliminates it completely) and then all the off band distortion artefacts are fed into the voltmeter which is pushing the left-most VU meter around (the meter was fixed at the 10% distortion scale with all these pictures). I fed sine signal to the horizontal, and the filtered output of the 330D to the vertical of the scope.
On to my rudimentary and probably unscientific analysis based on a 100 Hz signal: (NSFW tag due to heavy image content & loading love)
This pic is provided as a base line of what bypass LOOKS like on the scope. It should theoretically be a flat horizontal line, but some of the test equipment is over 50 years old, so we're living with a little ripple.
For a noise source the intuition wants to see jagged hell lines, but I believe this is normal. We have a more or less constant magnitude of noise floor injected over the signal, which results in nice smooth regions that are only interrupted by a crossover line. I did not compare the Static Fuzz to a Crustacean, as I have no built Crustaceans on hand - but my guess is that they would behave in a similar manner (when outputting white noise injected over signal). Nice, smooth, almost calming lines.
I'm guessing the trace crossover has to do with phase anomalies between the filter and tuned oscillator. Again, I'm just getting the hang of this test rig, so this is by NO MEANS DEFINITIVE. It's just eye candy, dig?
Here we see some actual distortion deflection atop the "meat" of the floor noise. Ultimately, this was the lowest output device in the batch, (as will be seen in the vertical deflections forthcoming) which is not a critique, but an observation. All units were above unity capable, as I recall, no complaints.
The Whores in only filter mode provided an interesting thought experiment. As stated, I'm just feeding these things a 100 Hz sine wave for the duration of this picture set. The filter only mode provide solid response in the low end, only to drop off in the higher range of the effect.
My conclusion was that the filter on the Whores, when pushed into the higher ranges did itself null the 100 Hz signal...
...resulting in all readings falling flat.
Whores fuzz has a healthy dose of distortion, showing over 3% on the meter (still sorting out the accuracy on this).
Filtered distortion, switch mode 1.
Filtered distortion, switch mode 2.
