‘82 Lead 800

Based on the early-80s descendent of the amp

we based our Plexiglas model upon, the ‘82 Lead

800 adds a higher-gain cascaded preamp design

and a master volume control. Unlike the high-

volume heads of the 60s, which needed to be on

10 to achieve an overdrive sound, this amp

could conjure up real distortion at any volume

level, and that made it very popular in the bur-

geoning 80s heavy metal scene.

‘85 M-2 Lead

Based on a classic mid-80s high-end tube combo

amp, the ‘85 M-2 Lead model delivers hot-

rodded overdrive and searing solo tones. With a

full complement of tone controls and indepen-

dent input volume, overdrive and master vol-

ume controls, the gain structure can be tweaked

to your heart's content.

The M-2 Lead emulation is based on the lead

channel with the fat, bright, and gain boost op-

tions on.

‘89 SL100 Drive, Crunch, and

Clean

Our ‘89 SL100 model is based on a late-80s high-

gain 100-watt tube head, which was popular for

its singing sustain and clear articulation. The

Bright switch on the Clean and Crunch models

boosts the high-end for lead lines and cutting

tones.

For the Drive model, we simulated a bright

switch modification that was popular for this

amp. Set to Normal, the amp is stock. With

Bright engaged, the treble boost that would nor-

mally happen at lower gain settings is removed,

which leads to a rounder, thicker sound. The

Bright switch circuit has progressively less effect

as the gain is raised, and no effect when the pre-

amp is set to 10.

Toggle the Bright switch on and off with the

SW2 button.
