Prepare for meltdown with the TWA KM-01 Krytical Mass®!

Based on the coveted Maestro Bass Brassmaster, Krytical Mass® was born from exhaustive critical analysis into the inner workings of that Holy Grail device and the few noble attempts that have been made to clone it.

Krytical Mass® spits out fat, formidable fuzz with a pronounced octave up as well as a more subtle octave down and a scorching, filter-like sweep on sustained notes. Muted notes will “kill” the fuzz with almost gate-like precision, yielding a super-tight, synth-like pulse that is simply addictive to play.

Where other replicas tend to be harsh and sterile sounding, Krytical Mass® is able to capture the aggressive yet warm & organic edge of the original Brassmaster using a unique complement of EQ and voltage manipulation controls.

One of the great mysteries of the Brassmaster is its unmarked transformer and how it was wound. Analysis suggests that this component may have actually been wired with negative polarity, so Krytical Mass® includes a switch to toggle between positive & negative phase wirings for additional tonal options.

Another unique feature of Krytical Mass® is the ability to adjust the symmetry of the transformer to taste, accentuating either 2nd order harmonics for more lows or higher-order harmonics for more complex waveform content.

Also on board are selectable HP, LP and BP filters with adjustable midrange to fine-tune Krytical Mass® to your particular tonal tastes.

Fuzz sensitivity of Krytical Mass® can also be controlled via external EXP pedal for dynamic manipulation of the fuzz to create synth-like drive swells and other interesting effects.

Set off your own nuclear chain reaction with Krytical Mass® - only from Totally Wycked Audio®!

*Please note, like all TWA Pedals, the Krytical Mass® will be manufactured in limited batches of 100.  Unfortunately we are unable to predict exactly when the next batch will be manufactured, however if these sell out quickly, we will definitely be making more soon!

Perfect size
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
I like this size. I’ve gotten the larger ones in the past, but my 45 pound dogs can’t get to the center. This size works much better for them. They love them.

my dog says NO
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
My dog sniffs both ends of this bone then walks away. I see in inside of it is very hard so I decided to soak it in some hot water for awhile and see what she does with it. If it works I will update. Update. Soaking didn't help. So that bone went in the trash.

My dogs love them
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
My dogs love these. They don’t last very long but my dogs are big, and they aren’t messy. I also like how they don’t stink like some chews.

Long Lasting Doggie Chew
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
My dogs love these. They provide a tasty hard treat for them to chew on for hours, and even days. Once too small for safe chewing, you soak them in water then microwave it into a "puff."My dogs know when they are getting them as the aroma is ok. I buy these often and keep them on hand.
