Info:
“Inspired by the Trainwreck Express amplifier (built by the late Ken
Fischer), the TWE-1 is solid-state pedal designed to emulate the
touch-responsiveness and clean-to-overdriven range you get from a
high-grade tube amp. Along with Volume, Hi Cut, and Gain controls, the
pedal has 3-position Cab switch (4×12, 2×12, off), a Presence switch
that provides three levels of high-frequency boost (post OD), a Voice
switch (Traditional and Modern British), and a bypassable Brite switch
that provides two levels of high-frequency boost (pre OD).
The TWE-1 with its Gain at noon or higher responded in an amp-like way to
changes in guitar volume and picking strength, delivering everything
from gritty cleans to richly saturated distortion textures. Thanks to
its strong output, the TWE-1 is suitable for clean boosting too. All
good stuff, but the standout feature of the TWE-1 is its powerful
tone-shaping ability. The Hi-Cut knob attenuates treble when turned
clockwise, and the Brite switch makes it easy to get the appropriate
sparkle with humbuckers or single-coils. The Cab switch beefs up the
low-end significantly in the 4×12 position (I felt the 2×12 setting
sounded best with my Deluxe), and the Voice switch lets you choose
between a thicker tone in the “M” position or one with more
upper-midrange emphasis in the “T” setting. The Presence switch set to
Hi restores shimmer when the Hi Cut control is turned up (a cool sound
in itself), and between all of these functions, the TWE-1 certainly
answers the needs of players who want a compact OD pedal with
exceptional sound and flexibility.“
The layout should fit in a 125B size box.

This is a buffered effect. Follow the layout to connect the footswitch.
