Yamaha's THR100HD Dual Amp
odeling amps have evolved rapidly as
software and circuits have improved
and become, dare we say, more organic sounding. The Yamaha THR100HD is a prime
example: a digital head that offers tube-based
tones in a remarkably flexible unit.
The basic skinny on the THR100HD is
that it's not merely two channels in a single
head but rather two completely independent
amps in one chassis. Labeled Channel I
and Channel II, each amp has separate
inputs and outputs that can also be used
simultaneously for a standard lead/rhythm
setup. The preamp sports five models
simulating classic tones: Solid (solidstate), Clean (Fender), Crunch (Vox), Lead
(Marshall), and Modern (Rivera-, Boogie-,
or Soldano-type saturation). The preamp
also provides separate channel and master
Volume controls, Presence, a three-band
EQ, and footswitchable reverb and boost
A knob in the back allows the player to
choose digital models of power tubes like
the EL34, EL84, 6V6, KT88, and 6L6GC
tubes. A variable output switch offers 25-,
50-, and 100-watt power, a choice between
Classic A and Class AB circuit emulations,
and an effects loop (though Y cables are
required for stereo functionality). A USB
output connects to a computer to deeply edit
reverbs, boost types, and noise gates, and to
upload IR speaker simulations.
All of these features get ramped up when
the head is combined with the dedicated
THRC212 cabinet, which has two different
Eminence speakers. And, each channel can
run to a separate speaker, which means the
user can set Channel I and Channel II as
fully separate rigs, adjusting the amp model,
power-tube sim, and speaker choice for each.
Two guitarists can even play through the
THR100HD head, each using their own amp
type, EQ, and speaker. The amp's versatility
also allows the player to have two guitars
ready to go at all times. Set up Channel I for
a single-coil Strat or Tele, and then dial in
Channel II for a humbucker-fitted electric.
Onstage, you could simply swap guitars and
adjust volumes for two vastly different rigs.
Plugged in, THR100HD delivers convincing amp models and allow massive control
over every aspect of your tone. Overall, this
won't replace a favorite vintage-style amp,
but considering the huge array of quality
sound choices at your fingertips - all in a
light, portable head - its immense ramifications quickly become obvious. The Yamaha
THR100HD is a tone-tweaker's delight with
a mind-boggling range of gig and studio
uses. - Pete Prown
WAMPLER PAISLEY DELUXE
Wampler Pedals' Paisley Deluxe combines
the Paisley Drive and Underdog, with
independent access to each and the
ability to blend them. Channel 1 replicates
the Underdog and has a Fat switch,
while a switch on Channel 2 (Paisley
Drive) adjusts mids from full to flat. It has
top-mounted jacks for each channel.

RAILHAMMER REEVES GABRELS
Railhammer's Reeves Gabrels pickups use
Alnico V magnets; the bridge unit has an
overwound coil while the neck pickup is
designed to sound like an overwound PAF.
Both pair well with other Railhammers.
The PRS Custom 24-08 has a maple
top, mahogany back and neck, Gen
III vibrato, and dual 85/15 humbuckers with a three-way blade switch and
two mini-toggle coil-split switches that
allow for eight pickup combinations.
