iamqman's review"Nice revise!"

Boss PH-1R Phaser

This is one of the most legendary phaser pedals in the world. When Boss set out to start building compact pedal they introduced three new pedals. They has the Boss OD-1, the Boss SP-1, and the pedal the Boss PH-1. Compounding on the success of these pedals launched a marketing campaign that would put Boss into the most successful guitar pedal company in the world. they have remained on top even since its inception. Several pedals like the TS9 and others have gotten a great hold on the market but nothing like Boss. After the success of the PH-1 Boss revised it with adding a resonance control knob and adding the "r" on the end of the name.

This is pedal that is design to phase much like you would hear a Leslie speaker do but much more versatile than a Leslie speaker. This pedal has only two control knobs and those are Rate and Depth. this will control the speed and how much mix will be in the dry tone.



* Controls: Rate, Resonance, Depth
* Connectors: Input, Output, AC Adaptor
* Current Draw: 11 mA (DC 9V)
* Weight: 400 g (.88 lbs)
* Input Impedance: 470kOhm
* Signal/Noise Ratio: Over 90dB (IHF-A)
* Recommended Load Impedance: Over 10kOhm
* LFO Speed: 100 ms ~ 16 s
* Recommended AC Adaptor: ACA Series


The tone of this pedal is quite good. The added resonance control knob added a lot of extra flavor to the tone. The biggest competitor to this pedal back int the day was h MXR Phase 90. That one had only one control knob and was very versatile in its tone.

This pedal has a great sound no matter where you get this thing dialed in. The rate and depth are very easy to control and find a good tone out of. I think both of them in the 11:00 position is the best sounding for what I do. I like a little phaser in some applications but not something that takes over the tone too much. This is nice setting where you can get a good sounding phase effects and still hear the rest of your dry tone in the mix.


These pedals were made form 1980 through 1985. The used market is the only way to go at this point. There are much better phasers now a days so this one is obsolete to me. I wold recommend getting an MXR phaser and that pedal is even easier to dial in than this one.

Boss PH-1R Phaser
Boss pedal phasing (it's marked on it), made in Japan, manufactures until 1985: it is simply a PH-1 which has a Contrle addition t rsonnance of those Rate (speed / rate) and Depth (effect) well enough to get a nice variety of colors of effects. It's good analog in an apple green watch case (like Granny Smith) well flashy and indestructible. Connectivity: between output AC-in, a suppo in bed!
Classic, solid, simple and effective: pure Boss really.


Very simple to use, it appreciates-controlling of rsonnance, adding a lot of nuances. One quickly gets and many varis phasing and inspiration. From the little subtleties color into sound, very marked effect and color everything is possible.
The manual I have not had, I can do without aisment ...


The effect is very effective, very appropriate color in all circumstances trsraliste.
I use it on Gibson and Schecter, With SD-1, a BF-2 and a Cry-baby and the whole spring (for now) on a small transistor 15W Line 6 (which suddenly I only use little effect).
In clean, really very good, regardless of the position chosen for the microphones; in overdrive: welcome in the 70's; distortion, it's still good. It behaves very well in the mix with the other effects and allows dmentes exprimentations with a well made Superior high-end multi-effects (I do not speak the same effects of the amp remaining when even very honorable).
It is a color effect to the sound as his watch case, very pleasant and efficient, has rotated very natural fawn.


I use it for a month. This is a rare bird, his views must. I tried Soundtank Ibanez, Boss PH-2 and PH-3 Electro-Harmonix Small Stone (Reissue and epoch): this is the compromise between ergonomics and simplicity that suits me best.
A must, if you jump on the cross !!!

rouliann's review (This content has been automatically translated from French)" The base"

Boss PH-1R Phaser
Ph 1r is the second pedal Boss Phaser output. And this is the best.


Ultra simple setup, as it is an analog pedal that wants, whatever the connection, it sounds.


I use it with my Telecaster.
The sound can be super disgusting, but that is precisely why she is excellent.
If you like the sound and pure digital. Go your way.
The Phaser will disgust you.


I for 5 years, bought € 40 in a mag deposit sale.
I do never separate.

Boss PH-1R Phaser
Made in Japan in the 80s, it is analog. it there's three potentiometers Control: Rate (rate effect), depth (intensity effect) and Res (feedback signal). input / output jack (6.35mm mono not stereo output).


Everything is very simple no need for manual


That's fine, we can go a very slight effect until psychedelic effects completely barred. No breath, the sound is of high quality. Only negative when the effect triggers the noise level tends to increase, but we can compensate by attacking text strings or slightly lowering the volume of the instrument. Personally, I use it with a bass ever before the power amp or preamp (never in the effects loop or after the preamp)


I use it for 15 years, first repeats at a friends, and finally I traded him against another pedal. This is one of the pedals that I use the most for years to create atmosphere or solos. I would do this choice without hesitation.
