Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Harley Benton PA-100 Power Attenuator.
User experience
-
High-gain settings can introduce a constant high-pitched squealing sound, similar to feedback, when using the line out.
Source -
Users report a -3dB drop immediately upon the attenuator being in the circuit, requiring EQ adjustments to compensate for tone changes.
Source -
Some users are satisfied with the PA-100 for home use despite its limitations, particularly due to its affordability and return policy.

Comparisons
-
The PA-100 is considered a clone of the Jet City Jettenuator and possibly Bugera models, offering similar functionality at a lower price point.
Source -
The PA-100's circuit for converting speaker-level to line-level signal may be causing noise issues, unlike other models like the TwoNotes Captor 8.
Source -
Owners report the PA-100 attenuates the bottom end more than the Torpedo Captor.

Features and functionality
-
The fan is powered by the signal feeding the speakers, maintaining the unit's passive status despite having a fan.
Source -
The XLR out is described as a low Z unbalanced line out, with possible EQ coloration affecting usability for some users.
Source -
The PA-100 safely serves as a load box without a speaker attached, provided the correct impedance input is used.
Source -
The PA-100 can cause noise and feedback issues when using the line out into an interface, but works well for cabinet power attenuation.
Source -
The PA-100 may not handle a full 100W of valve power safely, as it becomes very hot even at reduced master volumes.
Source -
The internal fan can become noisy under high load, potentially distracting during recording sessions.
Source
Use cases and applications
-
Silent recording can be achieved by using the PA-100 with no speaker connected and the attenuator dial set to 2.
Source -
Using the FX loop send as a line out bypasses the power amp stage, affecting the tone by losing power tube saturation.
Source -
The PA-100 is often used as a dummy load to connect a head to an interface for headphone play, avoiding cab transport.
Source
Value and pricing
-
The Harley Benton PA-100 is considered a budget-friendly option, costing significantly less than alternatives like the Torpedo Captor or Jet City Jettenuator.

A godsend
An absolute blessing for anybody who uses a tube amplifier. It allows you to run your amplifier nice and loud in order to get that gorgeous tube breakup without bothering your neighbours or damaging your ears. The only complaints I really have are that it sometimes distorts your signal a little at really high volumes, and it’s fugly. But that’s a good sacrifice for what you get in return
