Boutique amps and effects pedals can cost an
absolute fortune. However, with our range of effects
pedals the need for those specialist and expensive
units is at an end. Each one has been carefully
designed to give you the best possible range of
performance and maximum amount of control for the
minimum of cost.
Equally important, when you press the ‘off’ button,
your sound will return to being 100% pure and
untouched thanks to their completely passive bypass.
ED-1 Edward the Compressor
Add sustain to solos, even out attack and get rid of unwanted peaks
and troughs. For liquid leads, funky clean chords or choppy yet
consistent chicken pickin’, call on Edward the Compressor.
In addition, target the frequencies you want to compress with the
Emphasis control, which means that you can, for example, tighten up
or compress your bass notes and let your treble notes ring out.
Features: Controls for Emphasis, Volume, Attack and Compression.
Solid metal construction and passive bypass.
JH-1 Jackhammer
This metallic monster boasts two modes (O/D and Dist), each of which
is loaded with ungodly gain plus all the tonal control you need to push your
guitar’s sound straight over the edge. From cranium-crushing crunch and
scooped modern metal mayhem to savage slamming solos, it’s unique
dual-control contour section gives you fearsome flexibility across the
mid-range, allowing you to focus your tone. The JH-1 is the most extreme
distortion pedal on the planet.
Features: Selector switch for O/D and Dist modes, controls for Gain,
Master Volume, Contour, Contour Frequency, Bass and Treble. Solid metal
casing and passive bypass.
GV-2 Guv’nor Plus
Shedloads of gain and loads of level, the GV-2 has all the power and
tone of our original, much-loved Guv’nor pedal – and beyond!
The GV-2’s expanded Gain structure allows you to steer your guitar tone
through many different styles and adding one to your set-up is just like
adding another Marshall amp to your rig.
Features: Controls for Gain, Bass, Middle, Treble, Deep (for a tight and
resonant low-end rumble) and Master Volume. Passive bypass and solid
metal construction.
BB-2 Bluesbreaker II
This bluesy bruiser is effectively two pedals in one – a tonally transparent
booster that gives your solos that extra lift, and a truly valve-like overdrive
that’s so rich in second order harmonics it’ll make your guitar gently weep.
Blues Mode is reminiscent of the tonal and distortion characteristics of our
non-Master Volume amps such as the classic Bluesbreaker combo from the
1960s. If that’s not enough, the BB-2’s completely passive bypass means that
you don’t lose any of your guitar’s pure tone when the pedal’s not in use!
Features: Mode switch to select Blues or Boost. Controls for Drive,
Tone and Volume. Solid metal casing and passive bypass.
VT-1 Vibratrem
Take a step back in time to the British amps of the early sixties with the
Vibratrem’s authentic vintage effects. Its wave-shaping control allows you
to melt between two modulation pattern options, offering you everything
from groovy, trembling tremolos to psychedelic quasi-vibratos. The VT-1 is
as authentically retro as you can get and its passive bypass ensures that
your all-important guitar tone remains unaffected when you’re not taking a
Vibratrem trip. Features: Mode switch to select Vibrato or Tremolo.
Controls for Speed, Depth and Wave Shape. Second output for stereo
spread. Solid metal casing and passive bypass.

“It’s what every woman needs!”

“Kicking in the Bluesbreaker pedal is a bit like
creeping up behind old ladies and popping a
balloon behind their heads to scare them.
Dark, thick and satisfying.”
