The new WMD TRSHMSTR is a collaborative effort between WMD and
MSTRKRFT. TRSHMSTR features an aggressive combination of band-pass
filtering (FLTR) and distortion ( ). The DRV FLTR and DRV sections can be used
independently or together to produce a wide variety of tone shaping, from
subtle distress to full-on acid destruction. The s and s of the IN OUT FLTR and DRV
sections are cross-normalled, so you can run your signal through FLTR and into DRV
or vice-versa with no extra patching.
FLTR is a band-pass filter with self-oscillating resonance and three selectable feedback
types. It is calibrated to have a tonal range evocative of vintage wah voicings. The FLAVOR
switch controls the type and amount of FLTR’s resonance clipping. Our circuit is based DRV
loosely on Tube Screamer designs of old, but it has been painstakingly re-voiced to compliment
a wider frequency range and greater amounts of gain. We have replaced the original TS input
filter with a tri-mode high-pass filter ( ) that allows you to get everything from nasally HPF
grime to ripping bass fuzz. In addition to the three modes, the HPF DRV section features three
• FLTR is a nasty and versatile band-pass filter
• Three resonance FLAVORs change the
character of FLTR’s feedback saturation
• DRV section provides a wide range of overdrive tones
• The HPF switch gives you control over the amount of lows
allowed to enter the overdrive circuit
• The DRV section also has three unique FLAVOR settings
• CV control over FREQ, RES, GAIN, and TONE
• CV attenuverters for both FREQ and GAIN control
• LED indicators for FREQ, RES, GAIN, and TONE
• KEY IN for filter tracking.
UP: Lets the bass through,
flooding the gain stage with
more than the stock setting,
accentuating the zipper-like
overtones of the incoming
some low frequencies, but
UP: Medium resonance and grit
using Zener diode clipping.
MIDDLE: pulls out all the
stops (and clipping diodes) and
overtakes the incoming signal
DOWN: Heavily asymmetrical
silicon diode and LED clipping.
diodes create more odd order
MIDDLE: A less compressed and
more crunchy tone using LEDs as
DOWN: Symmetrical silicon
diodes create a compressed and
scooped tone with fuzzy gain.
POWER: +12: 56mA, -12: 53mA,
w/ reverse polarity protection
DEPTH: 25mm w/ power connected
