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. This tube was widely used in many early amplifiers, but it is most

famous for its use in the Vox AC-30. This was the amp used on the early Stones,

Beatles and Yardbirds records. The EL-84 has a wonderful musical character - it sings, it

growls, and it has great dynamic response. The harder you play, the more it distorts and

sustains. Back off on your attack and it "idles", cleaning up the sound. In short, EL-84's

are a ton of fun!

The first thing you'll probably notice about your amp is that it's very loud for its size. We

wanted to make an amp for the working guitarist - something that could cut it in most

club and casual gig situations. The 84-50 has more than enough kick to keep up with a

loud drummer and bass player. In fact, when we were testing prototypes in clubs

around town, the 84-50 had no trouble holding its own on a stage full of 100-watt amps.

Using the 84-50 live is simple. Just use your ears to dial in the EQ settings you need,

depending on the type of pickups in your guitar, the demands of the job, etc. Switch

channels to find a balance between clean and overdrive settings. A typical lead/rhythm

sound setting might be:

EQ/TONE CONTROLS

Even though both channels share the same tone controls, the 84-50 Tube

amp has been carefully voiced for a smooth natural transition between channels. By

switching back and forth a few times and adjusting the gain controls of each channel,

it will be easy to get the proper tone and volume balance between clean and

distortion sounds.

GAIN BOOSTS

The 84-50 has two gain boosts and a Crunch Boost, which are activated, by push-pull

pots on the front panel. Pulling out the overdrive control of Channel One actives a subtle

6 dB boost in both channels. Pulling out the OD control on Channel Two activates a
