You are now the proud owner of the Crate GTD65 three-channel guitar amplifier with advanced digital signal processing (DSP) and Channel Tracking. This rugged amplifier combines outstanding features with serious clean and distorted sounds. Digital Reverb, Chorus, and Delay provide you with a wide variety of sounds. Crate’s unique Channel Tracking feature automatically stores your DSP settings for each channel to memory. As you switch from one channel to another, the DSP settings for the selected channel are instantly recalled. The supplied three-button footswitch allows you to select channels and change the DSP bank (Bank A/Bank B) by “remote control.” A front panel 1/8" stereo CD input jack allows you to play along with your CD player, MP3 player, or iPod. A rear panel insert jack allows you to add even more effects by connecting an external effect processor. Like all Crate products, your GTD amplifier is designed by musicians and built using only the best components. Extensive testing confirms that this amplifier is the absolute best it can be. In order to get the most out of your new amplifier, we strongly urge you to read this manual before you begin playing. And thank you for choosing Crate. Here are some of the features packed into your new GTD65 Combo Amplifier: • 65 watts rms power output • 1 x 12" speaker • Three-Channel Operation —High Gain Channel —Overdrive Channel —Clean Channel • 3-band EQ on the Overdrive and Clean Channels • Proprietary “Shape” EQ control on the High Gain Channel • DSP Effects including Delay, Chorus, and Reverb sections • CD Input • Effects Loop • 3-Function Footswitch included • External Speaker jack • Built-in Chromatic Tuner 3 GTD65 Guitar Amplifier w/DSP and Channel Tracking Channel Tracking Your Crate GTD65 gives you the power of Channel Tracking. Once you select a DSP setting for each channel, Channel Tracking stores the settings to memory whenever you change channels. When you go back to that channel, Channel Tracking recalls those DSP settings automatically, without changing the DSP controls! For example: • Select the Clean channel. Set the Chorus control to “Flanger,” the Delay control to “Echo,” and adjust the Reverb control to your preference. • Select the Overdrive channel. Set the Chorus control to “Chorus,” the Delay control to “Slap,” and readjust the Reverb control to a different setting. (The DSP settings for the Clean channel are now saved to memory.) • Select the High Gain channel. Set the Chorus control to “Phaser,” the Delay control to “Echo/Eff,” and readjust the Reverb control once again. (The DSP settings for the Overdrive channel are now saved to memory.) • Reselect the Clean channel. (The DSP settings for the High Gain channel are now saved to memory.) When you reselected the Clean channel, the DSP settings previously stored in memory were automatically recalled. Switch to the Overload channel and the DSP settings you just stored are still there. You can change the DSP settings at any time. Once you set the DSP and select another channel, Channel Tracking stores the settings for you. Even when the amplifier is turned off, the DSP settings are stored and recalled the next time you turn it on. That’s the power of Channel Tracking! In addition, each channel has two DSP banks, Bank A and Bank B, when you use the supplied three-button footswitch (see page 8 for more information on using the footswitch). Channel Tracking also remembers which DSP bank was selected for each channel. 4 GTD65 Guitar Amplifier w/DSP and Channel Tracking The Front Panel 1 2 3 4 5 6 7 8 9 10 11 1.

Use this control to get the best projection and midrange tones for your instrument when using the Clean channel. 18. HIGH: This adjusts the treble frequencies. Use this control to attain a bright and lively sound for your instrument when using the Clean channel. 19-21. EFFECTS: Use these controls to apply and adjust the DSP effects. Complete information on these effects is provided on page 7. 22. CD INPUT: Use this 1/8" stereo mini jack to connect the output from a CD player, MP3 player, laptop, etc., to the amplifier. The signal at this jack is summed into a mono signal, which is sent to the internal power amp circuit. Use the output level control for the signal source to adjust the signal for the proper mix with your guitar. 23. POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed). The switch illuminates when the amplifier is turned on. 5 GTD65 Guitar Amplifier w/DSP and Channel Tracking The Rear Panel TIP RING 24 25 26 27 28 30 24. FUSE: The fuse protects the amplifier 28.

When the footswitch is connected to the amplifier as shown below, the “original” DSP presets are active for each channel when the #3 footswitch LED is illuminated. These are referred to as “DSP Bank A.” When the #3 button is switched and the LED is off, a second DSP preset may be stored and recalled for each channel — “DSP Bank B.” Note: DSP Bank B presets are only accessible when the footswich is connected to the amplifier. When the footswitch is not connected, only DSP Bank A is accessible. “LEFT” jack “RIGHT” jack Switch #3: LED ON = DSP BANK A LED OFF = DSP BANK B Switch #2: LED ON = HIGH GAIN CH/OVERDRIVE CH Switch #1: LED OFF = CLEAN CH LED ON = HIGH GAIN CH LED OFF = OVERDRIVE CH [only when Switch #2 is activated (LED ON)] 8 GTD65 Guitar Amplifier w/DSP and Channel Tracking Suggested Settings Sweet ‘n Clean: OUT AS DESIRED Just a ‘Lil Nasty: OUT IN AS DESIRED Politely Gritty: OUT IN AS DESIRED Down ‘n Dirty: OUT IN AS DESIRED Mean & Obscene: IN IN AS DESIRED 9 GTD65 Guitar Amplifier w/DSP and Channel Tracking System Block Diagram TUNER BUFFER INPUT CLEAN VOLUME LOW MID HIGH OVERDRIVE LEVEL OVERDRIVE GAIN CLEAN/ OVERDRIVE LOW MID HIGH OVERDRIVE/ HIGH GAIN HIGH GAIN LEVEL HIGH GAIN GAIN SHAPE MIX AMP DSP FLANGER PHASER ECHO INSERT ECHO/EFF POWER AMP CHORUS SLAP CHORUS SPEAKER DELAY REVERB EXT.
