Copyright © 2007 Revision A THIS PRODUCT CONTAINS INTELLECTUAL PROPERTY OF ATLANTIC QUALITY DESIGN, INC. AND IS NOT TO BE COPIED IN WHOLE OR IN PART, INCLUDING MECHANICAL, ELECTRONIC HARDWARE, COMPUTER SOFTWARE AND/OR INTEGRATED CIRCUIT DESIGNS. NO PATENT LICENSES ARE CONVEYED WITH THE SALE OF THIS PRODUCT. eStrap TM User’s Manual 2 Effects Unit Setup Designed in concert with Ned Steinberger, the eStrap wireless expression system is a revolutionary new effects control tool that is easy to use. • Connect the effects unit as shown in the picture. • The green light will start blinking when power is applied • The EFFECTS cable is an optional connection • Use only the supplied wall power adapter. • The effects unit has no foot switches, so you can set it out of the way, on your amp or pedalboard. Strap Sensor Setup A sensor on the strap detects the tension in the strap and sends it to the effects unit wirelessly. • Insert the two supplied AAA batteries into the strap sensor’s battery clip, observing polarity. • Strap on your guitar. • Push the button to turn the eStrap sensor on. The effects unit light will light solidly. • A light glows within the button when the sensor is on, and the light on the effects unit also comes on solid. Calibrate To calibrate the strap sensor to your playing style: • Press and hold the button on the strap sensor about a second until the light comes on steadily. • Release the button (the light blinks) and move the instrument neck through the desired range of motion. • Once the light stops blinking, the calibration is complete. You are ready to play. Calibrate with different ranges of motion to get different feelings and effects: Up Only Up and Down Down Only eStrap TM User’s Manual 3 Bypass To bypass the effects unit, just turn off the strap sensor by pressing the button. The light on the effects unit will blink while bypassed. The button is designed to toggle bypass with a quick tap. A high quality electronic bypass is used that introduces no distortion or tone change when bypassed, as long as the eStrap effects unit is powered. Using external effects control, when bypassed the eStrap effects unit maintains its last setting. Settings Guitarists love to tweak pedals to get new sounds. With the eStrap, you won’t even have to remove the cover to do this because tone tweaks are accessible from the outside of the box. Eight switches are available and have the following functions: Switch 1. Controls direction of wah vs. direction of motion Switch 2. Controls smoothing of strap action, for fast or slow response Switches 3-7. Controls wah tone, from gutsy growl to coyote screech (see Wah Tone below) Switch 8. Pedal wiring switch selects between two common wiring systems for expression pedals Use a small implement to push the seven switches on (right) / off (left). The pedal wiring switch slides from left to right. Experiment with the controls to get the response you like! Wah Tone The classic wah setting is had with switches 5 and 2 on (right), and switches 1, 3, and 4 off (left). Switches 3, 4 and 5 control the frequency response, and switches 1 and 2 control the shape of the response, Q, range and such. The wah circuit in the eStrap uses a vintage inductor like the original wahs of yesteryear. Wireless Considerations The eStrap is a wireless device that operates within frequency bands designated by the government for unlicensed devices. This means that other devices may interfere with the eStrap. If you experience interference, reorient the eStrap effects unit as that may reduce the interference. The eStrap operates on different frequencies than wireless guitar transmitters. Also please note that the two small black items on top of the effects unit are not switches! Do not step on them! They are radio antennas. When stowing the eStrap, be sure the antennas will not be damaged in a gig bag. The antenna on the strap sensor is a short wire. Leave it coming straight out from the sensor; don’t coil it up as that reduces the wireless range. eStrap TM User’s Manual 4 Also note that you do not have to be controlling your own sound with the eStrap. It’s possible for one guitarist to be wearing the strap and another instrumentalist to be connected to the effects unit! Isn’t that wild? Expression Pedal Use The eStrap can substitute for an expression pedal. This is very useful with capable effects units that can …

The eStrap™ system is called the “Strap-Controlled Expression System with Classic Wah.” It consists of a transmitter and a receiver. The transmitter is a battery-powered device that mounts on the shoulder strap of an electric guitar. Inside the transmitter is a strain gauge. It measures the varying amount of tension that the musician puts on the shoulder strap as he plays. The transmitter converts the strain gauge reading to a digital signal, operating in bursts at approximately 60 times per second. The digital signal is then used to modulate the frequency of a 916 MHz carrier. This FM signal is radiated by a short flexible wire that forms a 1/4 wave rod antenna. Normally placed approximately ten feet from the transmitter, the receiver is powered by an a.c. adapter. The receiver detects the digital FM signal produced by the transmitter and uses it digitally to create special effects on the guitar’s music, all under the control of the musician This report only presents the results of testing performed on the Model ESRX receiver. Transmitter testing is described in a separate report. The receiver’s radiated and power line conducted emissions were measured, as required for class B digital devices by Title 47 of the United States Code of Federal Regulations, Part 2, section 2.906, and Part 15, sections 15.33(b)(3), 15.101, 15.107 (b) and 15.109(a). The testing was performed in accordance with ANSI C63.4-2003.
