LEGACY 3: MIDI FEATURES MIDI PRESET MEMORY: The Legacy 3 will save the CHANNEL selection (1, 2, or 3), BOOST(on/off), REVERB(on/off) and LED backlight color in a MIDI program location (1 thru 100). The settings will be recalled when the same MIDI program number is received. Volume, Drive and Tone level settings will not be saved. To SAVE a MIDI program setting: First, set the amp features for saving. 1. Hold down the channel (1,2,or 3) button for the channel setting you wish to save. 2. Now press the other two channel buttons, and release all three at the same time. The REVERB LED will be flashing. 3. From your MIDI controller, select (send) the MIDI program number you wish to save. The REVERB LED will stop flashing, and normal operation is resumed. To change the LED backlighting color: 1. Hold down the channel (1,2,or 3) button to change the LED color for that channel. 2. Now press the other two channel buttons, and release all three at the same time. The REVERB LED will be flashing. 3. On the back panel, press and release the "SET LED" button to set the lighting color to GREEN, RED, AMBER or OFF. The REVERB LED will stop flashing. 4. Press and release any channel (1,2, or 3) button to save and exit. Normal operation is resumed. To change the MIDI receive channel: 1. Press and release all 3 channel SELECT buttons on the front panel. The REVERB LED will be flashing. 2. Choose MIDI channel 1, 2, or 3 by pressing the 1, 2, or 3 button. The REVERB LED will stop flashing, and normal operation is resumed. CC (CONTINUOUS CONTROLLER) COMMANDS: The Legacy 3 will respond to MIDI Continuous Controller ("CC") commands. This allows you to recall a MIDI preset, then switch ON/OFF different amp features on demand through your MIDI controller. CC parameters: #81: Amp channel 1 (any change on CC#81) #82: Amp channel 2 (any change on CC#82) #83: Amp channel 3 (any change on CC#83) #84: Boost (OFF=0-63 / ON=64-127) - toggle with MIDI footswitch in CC mode #85: Reverb (OFF=0-63 / ON=64-127) - toggle with MIDI footswitch in CC mode #89: LED backlight colors: (0-15:OFF) (16-31:GREEN) (32-47:RED) (48-63:AMBER) (64-79:OFF) (80-95:GREEN) (96-111:RED) (112-127:AMBER) HELP SECTION a) USING THE VAI "HIDDEN FEATURE" : One of the "hidden" features of the LEGACY amps is using a technique that Steve Vai requested be part of the amp for his own use. While playing on the lead channel with a generous amount of DRIVE (around 6), back off the volume on your guitar. You will find the channel actually "cleaned up" with your guitar at a lower volume. This is a great feature for playing both rhythm and lead without switching channels. You will also find that the amp will be very responsive to your "attack". An advanced player knows how to vary their attack when picking or strumming, and the Legacy 3 is designed to respond to this. b) FEEDBACK FROM THE LEAD CHANNEL: The Legacy 3 can easily feedback when the LEAD volume, DRIVE, TREBLE and PRESENCE are turned all the way up. Like other highly modified tube amps, this is normal. To help reduce feedback and noise follow these tips; - Stand with the guitar pointed away from the amp, and mute strings not being played. - Keep the DRIVE control set around 5 to 7 on the dial. Some of the best lead saturation will be at around 5-7, not 10. - If the V1 or V2 (12AX7A) has become microphonic, replacing it can help reduce feedback. c) TUBE REPLACEMENT GUIDE: It is not uncommon for tubes to malfunction during shipping. If your amp is not working properly (popping noises, bad ringing, or power tube problems), please refer to the following tube replacement guide. 1) 12AX7 LOCATIONS: V1 is located closest to the INPUT jack. The other tubes follow consecutively with V4 towards the middle of the chassis. V1 and V2 are the most critical tubes for noise problems with V1 being the most sensitive (try exchanging with V3). Replace these tubes if you have popping or a bad ringing in the Lead 2 or 3 channel. Note: Low noise tubes may be hard to find and must be tested for low noise. V3 and V4 generally do not generate noise into the amp if they are slightly noisy. V3 drives the Clean channel and Power Amp IN. V4 is the Phase Inverter for the power amp. If the power amp section is not working, check V3 & V4 by inserting a signal into the rear POWER AMP IN jack (it's gonna be Loud!). If the power amp still does not work, read about the EL34 power tubes V5 through V8. 2) The EL34 power tubes are the larger tube, located in the following order on your chassis: V5, V6, V7, V8. Normally you'll want to replace these tubes as a set. Please contact Carvin for our latest prices. Sometimes you can spot defective power tubes when they are glowing red-hot, or flashing blue, along with an audible hum in the speaker when the amp is idling. If this happens, shut the amp OFF immediately. Check the rear bias switch to be sure that it is selected for the proper tubes. Unplug the AC power to the amp. After the tubes have cooled down, remove the metal cover and carefully remove the spring retainers. Remove the tubes by rocking the tubes in a small circular motion while pulling them out. All tubes are keyed in the same direction. Running defective power tubes could damage the amp. It is recommended that you have a spare set of power tubes along with several 12AX7A preamp tubes.

SERVICE In the USA go to www.carvinservice.com Outside the USA, contact your dealer or go to http://www.carvinworld.com for your nearest service center. Include a written description of the problem with serial number and date of purchase. HELP SECTION 1) AMP WILL NOT TURN ON Check the power to the amp. Check for tripped circuit breakers, unplugged extension cords or power-strip switches that may be turned off. Check the fuse. If a dark brownish color or no wire can be seen within the glass tube, then replace. The amp may be perfectly fine but occasionally a fuse may blow because of high AC voltage surges. After the fuse has been replaced with the proper Slow Blow value and if the fuse fails again, the amp will require servicing. 2) NO OUTPUT with POWER LIGHT ON Tubes damaged in shipping will be the primary reason for your amp to not function properly. Please give us a call to help guide you through this simple repair. 3) KEEP YOUR AMP LOOKING NEW Use a damp cloth to wipe the controls on the front & rear chassis panels.
