Overview
The PT-15 is the latest innovation to come from Suhr. Three of the foremost
authorities on tone, John Suhr, his son Kevin Suhr and the legendary guitar
player and recording artist Pete Thorn have collaborated once again to
design a new, groundbreaking version of his revolutionary PT-100.
The PT-15 is a brand new evolution of the PT signature amp in a smaller,
lighter and lower wattage package. The 3 channels of tone arrived
after decades of research and development Pete and John conducted over
the years, yet with the expanded versatility of an on-board Reactive Load
I.R. AND impulse response loader, bundled with IRs from Celestion along
with seven proprietary IR blends made by Pete Thorn himself.
Now, the PT amplier has evolved once again to combine the best of the
analog and digital worlds, leveraging both to their fullest extent to create this
bar-raising amplier. Classic tube circuitry generating dynamics, overdrive,
saturation and harmonics while digital technology and using impulse re-
sponses to capture the highly complex frequency response which results in
the nuances of the sonic character of a speaker and its relationship to a mic.
This simply can not be replicated with an analog circuit. With the awesome
capability of a programmable IR for each channel that will automatically
switch to your selected IR when you switch your channels, you can use the
power of impulse responses to vastly alter the tone of your signal.
This makes the PT-15 I.R. the MOST versatile amplier produced today,
analog and digital with absolutely no compromises.

Connect the supplied AC cable
to this inlet to supply power.
Set this switch to match the impedance of the
cabinet(s) being used. When no speaker
cabniet is connected, set impedance selector
to 8Ω to match the internal reactive load.
When using this jack you MUST
have a load (Cabinet) connected,
This jack delivers full power and
volume to your cabinet.
When using this jack the reactive
load is enabled in parallel with your
cabinet, reducing overall volume by
-3dB SPL. (equivalent to half power)

I.R. Bypass
Use this as a direct line level out
from your amp for easy recording
and live applications.
Connect to a computer to
manage the installed impulse
response les.
Press to bypass the I.R. lter i.e.
no impulse response affecting the
tone.
Connect the supplied foot switch
here via stereo cable (TRS).

Channel 1 (Clean)
Things to know:
1. GAIN - Adjusts the overall gain of channel 1.
2. LEVEL - Adjusts the overall output of channel 1.
3. BASS - Adjusts the amount of bass. Turning it clockwise increases the
amount of bottom-end, giving you a fuller, richer tone, without losing
denition. Turning it counter clockwise will reduce the bottom-end for a tighter
tone, which is useful when performing at louder volumes.
4. TREBLE - Adjusts the treble. Turning it clockwise increases the amount of
top-end, giving your tone clarity and brightness. Turning it counter
clockwise will produce a warmer sound, ideal for dialing in smoother Jazz-like
tones.
5. BRIGHT SWITCH -Introduces added brightness and sparkle that brings out
a chimy organic top end.
The PT15 I.R. has a clean channel in a league of its own.
American voiced, bold, clear, punchy responsive tone with tons of
headroom.
☺HELPFUL TIP: Although channel 1 has no midrange control, the bass
and treble settings will interactively affect this channel’s midrange
response. Turning up the bass and treble will effectively scoop the mids.
Turning down the bass and treble will push the midrange front and center.
8
Channel 2 & 3 (High-Gain)
Things to know:
1. GAIN - Adjusts the overall gain of channel 2 or channel 3.
2. LEVEL - Adjusts the overall output of channel 2 or channel 3.
3. BASS - Adjusts the amount of bass. Turning it clockwise increases the
amount of bottom-end, giving you a fuller tone. Turning it counter clockwise
will reduce the bottom-end, which is useful when performing at louder
volumes.
4. MIDDLE - Adjusts the midrange. Turning it clockwise increases the amount of
mids. Turning it counter clockwise will reduce the mids and produce a
mid-scooped sound.
5. TREBLE - Adjusts the treble. Turning it clockwise increases the amount of
top-end, giving your tone clarity and brightness. Turning it counter clockwise
will produce a warmer sound, excellent for dialing in smooth uid-like lead
tones .
6. BRIGHT SWITCH -Adds brightness and sparkle.
The PT15 I.R. high gain channels are based on vintage modded British
tones, except more gain to spare. These channels shine at all settings, from
crunch to searing metal, low, mid and high gain, it's all there with rich
harmonic overtones and limitless sustain.
9
Presence & Master Volume
Things to know:
1. MASTER - Adjusts the overall volume output of all channels.
2. PRESENCE - Adjusts the amount of high frequencies added to your tone.
Turning it clockwise will add more sparkle.
The Presence & Master Volume controls of the PT-15 I.R. affect all of the
channels.
Speaker Outputs
The built-in 8Ω reactive load is always enabled UNLESS a speaker cabinet is
connected to the Reactive Load Disconnect (red ring jack) output. This
speaker output disables the internal reactive load.
10
Speakers Outputs:
Reactive Load In Parallel:
When using this jack the reactive load is enabled in parallel with your cabinet,
reducing overall volume by -3dB SPL (equivalent to half power)
Reactive Load Disabled:
When using this jack you MUST have a load (Cabinet) connected.
Using this speaker output disables the internal reactive load, delivering full power
and volume to your cabinet.
Impedance Selector:
The impedance must be set at all times to the total load on the amp. When the
internal Reactive Load is in use, it places an 8Ω load on the amp. If a cabinet is
used in parallel with the Reactive Load, the 8Ω internal load must be included in
the impedance calculation.
If playing through a speaker cab with the RL disabled, set the impedance to
match the connected cab(s).
One 16 Ω cabinet, set impedance selector to 16 Ω
One 8 Ω cabinet, set impedance selector to 8 Ω
One 4 Ω cabinet, set impedance selector to 4 Ω
If you plug two cabinets in to both speaker out, you must set the impedance
selector to the total load (impedance) of both cabinets being used.
Remember, if you are using both speaker outs the reactive load will be disabled.
However, the Line Out will still be active.
Two 16 ohm cabinets = 8 ohm total load
Two 8 ohm cabinets = 4 ohm total load.
(Using two 4 ohm cabinets simultaneously is not recommended)
