Congratulations on your purchase of the Mudhoney distortion!
It’s sound is meant for slight grit, plain old distortion or almost
fuzz-like tones, so make sure to sweep through the gain range to
get a feel for how the pedal reacts.
We recommend tweaking the gain knob and the mode switch to
find the right gain setting, because both will affect the gain, but
not in the exact same way - a high gain setting on the cleaner
mode may sound better to you than a low gain setting on the
high gain mode setting.
The tone control may seem subtle in the way it adds/detracts
high frequencies, but in use, this makes it easier to dial in the
desired response.
The output level can be boosted when turning the level knob
up, so it works just as good as a “push the front end of the amp”pedal. With a lower gain setting, the EQ curve in combination
with the level boost takes an already dirty amp sound to higher
levels of push, gain and raw-someness, without muddying up
the sound.
CONTROLSMUDHONEY - THE YELLOW ONE
Gain: Adjusts the level of distortion in conjunction with the
mode switch
Tone: Adjusts the high/treble frequencies
Level: Controls the output level. Settings above 12 o´clock
will boost the level relative to the bypassed signal. At maximum, the output level is boosted appr. 15dB
Mode switch: Controls the overall distortion level from
moderate to high-gain

SUBJECT TO CHANGE WITHOUT NOTICE

ORIGINAL CLASSICS
This pedal is a reissue of one of the very first stompbox series
made by T-Rex.
They were handmade in Vejle, Denmark using local suppliers
and “local” employees such as family members and friends of TRex founders Lars and Sebastian. Yes, the old, sought-after Mudhoneys, Albertas and Tremsters were made in a smokey, low-key
environment filled with passion and late-night soldering. We´re
talking small scale, big expectations, here.
The reissue pedals use the same leaded components and parts
as the old ones, but are wave soldered for higher precision and
quality. The bypass circuit has been changed to a true bypass
design, but other than that, it´s just like the old days. We even
stuck in some resistor values that were “slightly off the mark” but
contributed to the sound in a very positive way.
We are very proud to give re-birth to these three classics. We
hope they will keep the legacy of our red, blue and yellow “babies” alive while giving players a second chance for owning one
of them.
Please welcome back the Mudhoney, Alberta and Tremster!
