Congratulations on your purchase of the Seymour Duncan Research 84-50 Tube guitar amplifier. The 84-50 is the product of an intense research and development effort. Our object was to provide guitarists with an affordable, all-tube amplifier, which sounded great. The 84-50 is based on classic principles of tube guitar amplifier design. An all-tube preamp drives a quartet of EL-84 power tubes, which provide the sweetest, most musical tone possible.

PERFORMANCE APPLICATIONS AND GUIDELINES The name of the 84-50 Tube amp reflects its design - the amp uses a quartet of EL-84 type tubes to produce 50 watts of power. The EL-84 tube was chosen specifically for its rich, sweet tone qualities, especially when pushed to distortion.

IMPORTANT: In order for the Quadra tone Footswitch to have full control over the various functions, make sure the amp is in the green (clean) channel and all Boosts and Crunch are off (pushed in) on the front panel. Then simply plug the Programmable Footswitch into the "4 Function"...
Sample Settings Note: This combination uses the red channel only. GainBoost2 and Crunch Boost are pulled to achieve "Scorching Lead." To achieve remote switching between these sounds, a Quadra Tone programmable footswitch must be used.
