The PDI-03 is the legendary predecessor to the PGA-04 Speaker
Simulator. It is a re-issue of the early 90’s model with the
"battleship gray" housing and metal knobs. The Palmer Speaker
Simulator PDI-03 is a combined signal splitter, DI-box, and
(when used as a load box) power soak. It comes in a single space
rackmount unit. Especially designed for electric guitars and
basses, all functions have been optimized for live and studio
"Our "Sucker".It is a attenautor for amps up to 100 watt.
We build 4 different models from the standart Sucker till the Sucker Deluxe +.They all can handle 100 Watt max. but have additional feateres like compensated
D.I. and or EQ plus headphone ability.Of course it is working as a load box too.The biggest one is the Double Sucker,you can thik of it as two load boxes in
one case,so you can have two independat volumes and switch between them via footswitch." [Source and images: Stefan Huther, Redstuff Amplification, email 25/1/2013]
It's the size of a small effects
pedal: 4.67" L x 3.68" W x 1.18" H.
Will work with ANY amplifier 22w or less with the light
compression, 30w with it off.
Filament BULB Compression Mode
This mode runs the attenuated signal through a Swart jewel lamp
filament, bringing a subtle tube compression/brown sound
goodness. NOTE: This switch ONLY works with LEVEL chickenhead at
Bypass compression mode
Removes the light compressor out of the circuit for more natural
dynamics. With level at 12oclock, this is least
attenuation/highest volume setting.
Heavy duty 3 position Switch
This main chicken head switch allows you to switch between FOUR
different attenuation settings. At first setting, or 12oclock,
the NL can cycle between the COMP and DECOMP switch which brings
two levels. DECOMP is least attenuated or loudest setting with
COMP position bringing more attenuation via the bulb filament.
Turn the switch to 2oclock will bring more attenuation,
bypassing the DECOMP/COMP switch. The lowest setting is about
the same loudness as your guitar strings.

Review I owned one of these
for a while to try and tame my VHT Pittbull 45 watt EL84 combo.
It certainly does reduce volume, but I felt that at high
attenuation levels it removed all of the dynamics and harmonics.
I did not keep it long. I now have a THD Hotplate built
into my THD Univalve - I don't need to apply as much attenuation
to get the volume I want with the smaller amp - I think they are
mated quite well.
