Hello everybody,

my name is Chris. I am new to this board and really looking forward for nice input and insights from you guys. I'm a huge fan of my trusty THR 10 and about to pull the trigger on the new THR 30 II w. Today I read the end of the new manual online, where the modelled amp list is described. Not beeing that much of gear head I am now wondering what real amps these descriptions exactly referr to? To me it seems like they are not the same as in the old 10/10c/10x amps - or maybe the are just in another order, could that be? May anybody with more knowledge of the listed amps enlighten me?

Greets from Germany,

Chris

Hi Chris, welcome to the forum and the string section. :D

Yamaha are careful not to mention any brand names of the amps modelled,
but the amps in the THR-II models are not identical to the older THR-5/10/10C/10X75A models,
even though some represent the same brands/types, they are probably upgraded a bit.

At the moment I don't have a list telling what's what, but here is a copy paste from page 19 in the THR-II manual.

------------------------------------------------------------------------------------------
THR-II Amp Modeling List
------------------------------------------------------------------------------------------

Classic
----------
Clean
A low-gain preamp for sparkling American-style cleans, with 6L6 tubes in the output stage
for brightness and a strong midrange.

Crunch
EL84 power tubes in a true Class-A configuration with a highly responsive EQ for rich,
complex harmonic tones and warm overdrive. Inspired by British chime.

Lead
A low-gain preamp with an EL34-based power section
that breaks into classic British overdrive as the master volume is pushed.

Hi Gain
Powerful modern distortion that fills out as the high-gain preamp is pushed.
Tread carefully after 12 o'clock.

Special
12AX7 and 6L6 tubes in pursuit of the "Brown" sound. Set the gain around 11 o'clock for classic rock crunch,
or crank it for saturated rhythm tones.

Bass
Woody, vintage tone with late breakup.

Acoustic
Designed for acoustic-electric guitar, modeling the response of a boutique condenser
microphone.

Flat
A neutral tone with no amp or speaker modeling. Great for connecting other instruments to
your THR.
------------------------------------------------------------------------------------------

Boutique
----------
Clean
A low-watt EL34 design. Turning up the preamp gain will thicken up the cleans,
then push into bluesy overdrive.

Crunch
A deceptively simple amp circuit with just a single 12AX7 and EL84.
A full, no-frills tone that is highly responsive to picking dynamics.

Lead
A version of the Classic/Lead circuit, modified for extra gain with a darker tone and
scooped mids.

Hi Gain
ECC83s into 6L6s for high gain with a highly responsive EQ, inspired by German engineering.

Special
Four 12AX7 preamp tubes into 6L6 output tubes. Tight, fast tracking for crushing highgain.

Bass
Full, modern tone that breaks into a fuzz-like overdrive when pushed hard.

Acoustic
Designed for acoustic-electric guitar, modeling the response of a boutique tube microphone.

Flat
A neutral tone with no amp or speaker modeling, and a slight bass boost.
Great for connecting other instruments to your THR.
------------------------------------------------------------------------------------------

Modern
----------
Clean
A boutique, low-watt EL84 design that adds fullness and sustain as the master volume is
turned up. A great match for neck pickups.

Crunch
A mid-volume boutique design with 6550 power tubes. Listen for tight bass response and a
singing sustain.

Lead
A high-gain design with 12AX7s into EL34s, for the tone that defined 1980s hard rock and
heavy metal.

Hi Gain
A boosted version of the Classic/Special amp, with even more gain for aggressive rhythms
or searing leads.

Special
A classic overdrive circuit before the preamp tightens low-frequency response and provides
even more gain. Ideal for extended-range guitars.

Bass
Vintage voicing with early breakup for overdrive that works well with bass or guitar.

Acoustic
Designed for acoustic-electric guitar, modeling the response of a boutique dynamic microphone.

Flat
A neutral tone with no amp or speaker modeling, and a slight mid scoop.
Great for connecting other instruments to your THR.

Hi Peter,

thanks a lot for your reply. That list you copied in here is the one I was talking about. I‘m sure for real gear heads it‘s pretty obvious which is which just by the description - but personally I‘m only able to recognize a few. Well, time will tell... I‘m really awaiting the sales start in Germany. About 2 more weeks from now on.

Chris
