3. reverb or other effects take advantage of the stereo effect loop to insert the reverb between the preamp and power amps Lead Synth Keyboards Need to add a searing edge to a lead synth track One trick is to run the synth through a guitar amp Go easy on the distortion at first just running the synth through the Signature 284 set for clean will produce a dramatic effect If you re tracking with effects insert them in the effects loop Stereo Keyboards Many digital keyboards can benefit from the addition of some tube warmth One obvious candiate for tubification is any organ sound particularly B 3 with rotary speaker Run the stereo outputs of the synth into the effects returns of the Signature 284 connect the Recording outputs to the mixer and set the Volume controls to dial in an appropriate amount of grind 15 Applications 16 Vocals Acoustic Guitar Digital Effects Re Amping Lexicon Looking for a more radical effect than can be obtained with a tube mic preamp Depending on how drastic you want to be run the vocal through either the Guitar input easy on the gain or the effects return Here again the Signature 284 has something to offer as an alternative way to process a source There are several approaches all yield different but musical results If the acoustic guitar is a mono source be sure to experiment using the guitar input gain and tone controls as well as bypassing the preamp
