Trilogy™ Manual 1.1

Foreword

Even in the new millennium, classic rock, blues and metal sounds of last century’s great guitarists continue to shape musicians and audiences’ tastes in tone. Back in the day, flexibility wasn’t top on the list of amp attributes: Two channels were standard, three a luxury, and four MIDI switchable channels a dream at best. And now monster nu metal sounds, detuned guitars, blistering bare-knuckle riffs and clean yet heavily effected sounds have gained currency in the repertoires of countless rock bands. Yesteryear’s tube amps are no match for today’s sonic diversity challenge.

Enter Trilogy™. You have chosen a tube amp offering a rich feature set. Its mighty arsenal of sound-sculpting features that makes the dream of total mastery over tone come true. It boasts four independent channels tweaked to deliver markedly different slices of the tonal pie, a further variation on the fundamental sound in the CLEAN and CRUNCH channels each, and a whopping 128 effect combinations that can be stored via MIDI in combination with these six sounds. In a nutshell, you get plenty of sonic firepower to make every

gig pure playing pleasure.

Things to do before operating

the Amp

A word of warning before you fire up your new amp: It’s loud! High volume levels can cause hearing damage. Always twist the MASTER VOLUME knob to the far left-hand position before turning on the amp, and then slowly rotate the knob clockwise until you dial in a level that is comfortable for your ears and suitable for the venue. Keep those levels well under the pain threshold!

Check the voltage rating displayed next to Trilogy™'s MAINS INPUT to make sure it matches your local mains current before you plug the amp in. Ensure plenty of air can circulate around your amp's ventilation ducts. Place the amp on a sturdy, secure base and avoid exposing it to mechanical shocks and extreme temperatures that could endanger the device or your and others' safety.

The manufacturer disclaims any liability or responsibility what- soever for any damage or defect to this and other devices resulting from misuse.

Powering up

First plug the speaker cord into appropriate Speaker Out on the head’s rear panel. Your choices are a 4-ohm output, a pair of 16-ohm outputs, an 8-ohm output and a 16-ohm output. More on this in chapter 2 – Rear Panel Connections and Control Features. Plug the other end of the cord into the speaker cabinet’s input. This amp-to-speaker connection and impedance matching are vital to every all-tube amp’s life! Tube amps operated without the load of a connected speaker or at an insufficient impedance level die!

Plug the head’s mains cord into a wall outlet and power the amp up by engaging the MAINS switch. Allow the tubes to warm up before you begin playing. First plug one end of the guitar cord into the guitar, and then the other end into the amp. Flip the STANDBY switch to bring those glowing tubes to life.
