- Page 3 30 years of research and development in amplifier design. It is by far the finest work I’ve produced in all my years as an amplifier designer/builder. The Sugarland was conceived as a craft made, masterbuilt product in which every aspect of production work is performed either myself or by an assistant under my direct supervision.
- Page 4 While conventional treble/bass controls offer simple variations of a single voice, the Sugarland tone controls vary the voicing, gain, and overdrive characteristics all at once, for much greater tonal variety.
- Page 5 Even the footswitch receives special attention, with a lacquered tweed enclosure and bakelite top plate. Custom made components such as these are another example of impractical techniques that achieve results that go beyond typical “boutique” guitar amplifiers.

2. Top Panel Controls Guitar Input The Sugarland provides a single input jack on the top panel for connecting your guitar or pedalboard. This jack is a standard ¼” mono type which is compatible with any standard guitar or instrument cable. -
Page 9: Master Volume
Master Volume While the Volume control sets the input gain of the preamplifier, the Master Volume control adjusts the output level of the preamplifier. It’s important to understand the different functions of the Volume and Master Volume controls in order to dial in the sound you need. In general, the Volume control determines the amount of overdrive and distortion, and the Master Volume determines the overall volume level. -

3. Back Panel Controls AC Line The AC Line input is an IEC type connection for use with an appropriate IEC-terminated line cord for connection to an AC power source. The line voltage specification printed underneath the connector outlet indicates the required voltage and frequency of the power source. This specification will vary depending on the country to which the amplifier was shipped, so please refer to the voltage specification printed on the back panel of your amplifier, as it may be different from that shown in the illustration above. -
Page 11: Speaker Jack
Extension Speaker The Extension speaker jack is provided for connecting additional speakers to the amplifier. This jack is wired in parallel with the main speaker jack (located on the underside of the chassis). When you attach a speaker using the external speaker jack, it will be connected in parallel with the internal speaker, and the internal speaker will remain operational. -
Page 12: Operation
If you don’t connect the footswitch, reverb and tremolo are still fully functional. Connecting your guitar or pedalboard The Sugarland has a single instrument level input on the top panel of the amplifier. It is intended to be connected directly to your guitar or to your effects chain / pedalboard. -
Page 13: Dialing In Your Sound
5. Dialing in Your Sound Preamp The preamp design was conceived as a purist 1-channel design with a minimal number of controls but capable of an unusually wide range of classic voicings. Voicings span from a sparkling late 60’s clean tone to a thick, to a woody tweed tone, to a crunchy plexi tone. This full range of voicings can be dialed in using only the bass and treble controls. -

Where to Place the Amp The Sugarland was designed to sound best sitting directly on the floor. In general, it will have the best tonal balance when sitting on the floor. However, if you find that the low bass is overly exaggerated in your room, then elevating the amp a few inches off the floor may help. -

7. Tube Installation and Replacement Tube Quality Currently manufactured tubes are built in China, Russia, and the Czech Republic, and are not built to the same quality standards as tubes manufactures by the U.S. manufacturers in the “glory days” of tube manufacturing. We musicians choose to use to vacuum tubes because of their tonal qualities, but we need to accept that the tubes available to us these days can be imperfect devices and are most certainly the least reliable component in the entire amplifier. -
