Fryette PS-100 Power Station Dual-Mode Amplifier

Unique attenuator and tube amp built into one portable unit
MFR# PS100

Product Description

The Fryette PS-100 Power Station Dual-Mode Amp is an easy to use Power Attenuator for controlling the volume of high-powered tube amplifiers with none of the drawbacks of a conventional attenuator. The PS-100 features two sets of remote foot-switchable front panel Volume, Presence and Depth controls for maximum live performance flexibility, and a powerful Dual 6550 100 W Mono-Block for unparalleled punch and dynamic range.

If you have ever used a traditional Power Attenuator, you have already experienced the loss of tone and dynamics of your amplifier at various volume settings, and the frustration with the rotary level switch that always seems one step too loud or one step too quiet.

The Power Station not only solves all of those problems, but also provides you with more sonic options in one convenient package:

  • Preserves tube amplifier tone at any volume setting down to whisper level
  • Preserves and enhances the dynamic feel and speaker response at any volume
  • Maintains natural speaker/power amplifier interactive behavior
  • Two sets of remote foot-switchable Volume, Presence and Depth controls for maximum live performance versatility
  • Post-distortion Foot-Switchable Effects Loop provides a 100% analog signal path
  • Balanced XLR and Unbalanced 1/4” Adjustable Line Outputs for direct recording or live performance signal processing
  • True Impedance Matching, including 2/4, 8 or 16 ohms for both the amplifier and cabinet to optimize sonic performance while preventing damage to your amplifier
  • Remote bypass function using the Power Station Remote accessory (sold separately)
  • Completely safe for any tube amplifier

A Powerful Re-Amping Tool

As a re-amper, the Power Station breathes new life and utility into your favorite gear. Now any small amp, preamp or modeler can cut a live gig with a full band

  • Crank a mini amp to the threshold of destruction, then adjust the Power Station to preserve the original tone or create an entirely new identity for it
  • Perfect as mono power amplifier for guitar preamps, floor preamps and modeling preamps
  • Ideal as an effects power amp for a Wet/Dry amp rig or a monitor power amp for live modeling direct to FOH
  • Great as a desktop power amp for adding tube power to direct recordings for any instrument or signal source
  • Protect your delicate vintage mics by keeping speaker cabinet volume low in the studio
  • No A/D/A conversion, therefore NO latency

Silent Mode

The Silent Mode feature provides a versatile reactive load for silent recording using low or high-powered tube amplifiers. In Silent Mode, the Balanced XLR Out and Unbalanced Line Out remain operational even with the AC power disconnected. Note: Unit should remain under power when used with high-powered amplifiers to maintain safe operating temperatures.

The Power Station 100 provides a variety of performing and recording solutions for every kind of playing or performing application/environment and breathes new life and functionality into any amp large or small.

The Fryette PS-100 Power Station Dual-Mode Amp is a tonal GAME-CHANGER! I've played through Marshalls for most of life (I started playing guitar when I was eight years old), which is longer than I care to admit! I used a number of attenuators years ago, but was never quite satisfied with the tone. I have been playing through JCM-900 50-watt heads, which have a nice master volume that doesn't require a need for an attenuator. But last year I acquired what most would consider to be the "Holy Grail" of Marshalls, a late 1960s Super Tremolo 100-watt Plexi full stack! The head has been modded with master volumes for each channel already (very well, I might add), but you still have to crank the shit out of the amp to achieve the tone from God, which it provides in spades! While the tone is like no other, I still would like to preserve the hearing I have left! Which brings me to the Fryette unit. When I say a "tonal game-changer," I am not kidding. The unit works flawlessly and allows me to achieve the tone of a cranked 100w Plexi, at a decibel level that doesn't demolish my studio/rehearsal space in my home or render me deaf, all the while maintaining that heavenly cranked Plexi tone. The unit is very well-designed, and they also have a nice rack mount kit that works great! I loved the Fryette so much that I bought one for my other guitarist, who "only" has a Marshall JMP stack (lol). He thinks it's the greatest attenuator unit he's ever played through, as well! We love them so much we are trying to keep them a "trade secret" here in Minneapolis/St. Paul, but I guess I just let the cat out of the bag so to speak with this review...Johnny O'Neil

Outstanding piece of gear! It is everything I'd hoped it would be. I use it to attenuate my big bottle amps and also to power my Kemper into a guitar cab. The only con is that I wish I would have gotten one sooner!

By TROY W on February 6, 2023

Love this thing. It's my one and only attenuator so I can't speak much about comparisons, but the tone is great! It has really tamed my touchy Tweed Deluxe amp. I like that I can get on the edge of breakup and still be in the same room. My wife is a big fan, too! I like too that I can amp that up to 100W, should the need arise. Very versatile with two channels, foot switch control, and FX loop.

I love what the Fryette PS-100 enables me to do with my amp. I just wish it’s cooling fan was a bit quieter

On one hand, I waited too long to buy a Power Station. On the other, I waited long enough for the PS-100 to be introduced. This thing is tremendous - and you'll have no trouble finding *many* testimonials that say the same.

I bought an OX a few years ago primarily as an attenuator. A waste of money for my use case, as to me it sounded no better than an old THD Hot Plate resistive attenuator. Even the onboard speaker modeling left me cold.

Finally, I thought, "I don't care for the OX; I don't use it...now what?" Number one: I wanted to play through my cabs with attenuated tube amps, and I strongly dislike Class D amps for guitar cabs - that eliminated the Waza Tube Expander...Number two: I wanted continuously variable attenuation. Third, I wanted minimum tone suck. Fourth, an FX loop would be a welcome feature for my older amps.

The earlier generation PS and PS-2 reviews must have impressed me over time to the point that when I saw the PS-100 specs and features I pulled the trigger immediately.

The build quality of this unit really shows the value of its pricing, as does its sound quality and transparency. The massive headroom afforded by the 100W pair of big bottle 6550s is noticeable even at low volumes. There's a certain punch and instant transient response when you've got that kind of tube power behind the guitar signal.

The three-way bass and treble switches offer the option to tailor the reactive load's response - and the amp reacts accordingly, while the presence and resonance controls are located in the power amp's circuitry. The resonance control is especially useful at low volumes to give the sound some substance.

The line out level is adjustable now, and having two separate channels is something I use all of the time. The connectivity and switching options are thoughtful and practical.

I tested the line out by profiling an amp with my Kemper. The PS-100 created a better direct profile than studio mics, a Countryman DI, or the OX. Not to mention that my Kemper played through the PS-100 and a 4X12 sounds a 1000% better than it ever has (and I've got the built-in Kemper 400W Class D power amp - which is absolutely lifeless).

TL;DR - This is a swiss army knife tool for guitarists live and in the studio, and I can't recommend it highly enough.

This piece of gear has become indispensable to me! The tone is perfect at every volume! Simply spectacular.

By Brian W on December 16, 2021

Bring more voicing with 2 3way switch (edge-brite-flat)&(deep-warm-flat) give’s my amp more tweekability plus a loop in bonus. My amp alone already sounded great, this piece of gear made it even better! Everyone should get one since you can benefit from it with any of your present and future amps, the sound quality is just out of this world, it’s stunning how good it is!

By Charles T on October 19, 2021

This is the best unit out there!

By mark j on September 8, 2021

Bought this for dual purpose use. Mainly to power my rack of preamps for recording but also for the attenuation. It excels in both areas. Big and punchy through my cabs and knocks down amps for silent recording. The rack kit was easy to install as well.
