How to build an effects pedal for reverb.
This pedal produces sweet warm reverb using the Belton Digi-Log module. It operates on a 9V battery or
AC adapter (center negative), which are not included. When completed this pedal draws considerable
current and battery life will be short. The use of an AC adapter is highly recommended. This effect works
best when placed at the end of your effects chain.
THE VERB DELUXE (K-915)
Warning: This circuit was designed for use with a 9 VDC power supply only.

FINAL ASSEMBLY REFERENCE DRAWING
This is a large version of the final assembly drawing. Refer to this drawing as you make your way through each step of the instructions. Before you make a new
connection at a particular terminal or solder lug, notice how many other connections will be made at that terminal. That way you can decide whether it’s best for
you to solder the connection and leave space open for future connections or hold off on soldering until after every connection at that location has been made.

SOLDERING TIPS
1. Bend the component lead
and wrap it around the
connection point.
2. Wrap the component lead
so that it can hold itself to the
connection point.
3. Heat up both component
lead and connection point with
the soldering iron.
4. Apply solder to both
component lead and
connection point.
2. Apply fresh solder to mix in
with old solder joint
1. Heat up old solder joint
with the soldering iron.
3. Use a de-soldering tool to
remove the old solder joint
while it is heated.
De-Soldering Tip
6
It is important to make a good solder joint at each connection point. A cold solder joint is a connection that
may look connected but is actually disconnected or intermittently connected. (A cold solder joint can keep
your project from working.)
Follow these tips to make a good solder joint. Take your time with each connection and make sure that all
components are connected and will remain connected if your project is bumped or shaken.
Bend the component lead or wire ending and wrap it around the connection point.
Make sure it is not too close to a neighboring component which could cause an
unintended connection.
2. Wrap the component lead so that it can hold itself to the connection point.
Touch the soldering iron to both the component lead and the connection point allowing both to
warm up just before applying the solder to them.
Be sure to adequately cover both component lead and connection point with melted solder.
Remove the soldering iron from your work and allow the solder joint to cool. (The
solder joint should be shiny and smooth after solidifying.)
Cut off any excess wire or component leads with cutting pliers.
Clean the soldering iron's tip by wiping it across the wet sponge again after making the
solder joint.

SECTION 1 – Mount Large Components
7
Stripping and tinning wire and soldering. Throughout these instructions you will be told to strip
and tin a length of wire numerous times. Unless noted otherwise, cut the wire to the length stated in
the instructions. Then strip ¼” of insulation off each end. Twist each end of the stranded wire, and
apply a small amount of solder to each end (tin the wire ends). This will prevent the stranded wire
from fraying and will make the final soldering much easier.
Please refer to DRAWING 1 and DRAWING 2.
Orient box with two 3/8" holes and one 1/4" hole on top.
Mount the LED using the hardware provided. The Anode (+)
terminal should be oriented towards the top side of the enclosure.
The Verb Deluxe enclosure has a high gloss finish. To avoid scratching the surface while assembling this kit, you may
want to place a soft cloth, towel or similar item over your work surface.
The Anode (+) side of the LED is
indicated by a slightly longer lead
and/or a positive sign.

Using the four screws, nuts and lock washers provided, fasten the six
terminal strips to match DRAWING 2. You might find it easier to mount
the long (8 lug) terminal strips by fastening the first screw and nut loosely
at first, then tighten them once the second screw and nut are in place.
It may be necessary to angle the terminal strips forward with your fingers so that the terminals are
not pressing against the sides of the enclosure making it difficult to mount the components.
Mount the input jack in 3/8" hole on the left side of the enclosure with the hardware provided. The
washer goes under the nut on the outside of the enclosure. Make sure the center solder lug of the
input jack is facing up. Correct positioning of the jack will make soldering connections much easier.
Mount the output jack in the 3/8" hole on right side of the enclosure with the hardware provided.
The washer goes under the nut on the outside of the enclosure. Make sure the two solder lugs are
in their most upright position before tightening the nut.
Mount the 100K pot in the 3/8" hole on the top right and the 500K
pot in the 3/8" hole on the top left. Their solder lugs should be
directed toward the bottom side of the enclosure. (You can bend
their thin guide tabs with pliers so that the pots mount flush
against the enclosure surface).
Mount the DC power jack in the 15/32” hole on bottom left side of box. Orient the solder lugs on the
power jack so that the center-pin lug is facing the bottom side of the enclosure.

Mount the footswitch in 15/32” hole in center of box. The nylon washer
goes under the mounting nut on the outside of the enclosure. The lock
washer mounts on inside between the enclosure surface and the other
nut. Make sure that the footswitch is oriented to match DRAWING 2.

SECTION 2 – Prepare BTDR Reverb Module
Pin 4 will not be used. Strip a 3/8" piece of insulation from the wire provided
to use as an insulating sleeve for pin 4. Gently press this piece of insulation
over pin 4 of the reverb module.
SECTION 3 – Wire Large Components
Please refer to DRAWING 3.
Please note that each terminal has been numbered as
illustrated here and will be referred to as a “terminal #_”
when connecting different components and wires
throughout the assembly instructions.
Strip and tin a 6" piece of wire and connect to terminal #19 and the anode (+) terminal on the LED.
Solder the connection on the LED and trim the excess lead.

Now cut:
One 5" piece of wire for pin 1
Three 3" pieces of wire for pins 2, 5 and 6
One 2" piece of wire for pin 3
Strip and tin ¼” on each end of these pieces of wire. Bend one end of each
wire to form a small hook that can be slid around each pin. You can bend
the pins out slightly to allow more room if needed. Gently crimp the hook
ends of the wires to their respective pin numbers and solder.
