Pedal Options

Spares package:
Comprossor spares - NOS CA3080E chip, 3PDT switch, in/out jack, 2 screws $20 [Add $20.00]Hard to find chip and some useful spares in case of breakage.

NOS 1979 RCA Compressor chip $5 [Add $5.00]We always use New Old Stock (NOS) CA3080E chips in our comps, I don't think any other well-known brands are still using them. They were made by RCA, then Harris, then Intersil as the company was renamed over the years. We have some original 1979 RCA CA3080E chips that I have been saving for years, so I am putting them up as an option. I don't think they sound much different, but they are the exact same ones used in the old grey Ross compressors so it's pretty cool to have one in your pedal.

Add a shirt:

Large Analog.Man Bicomprossor with many options.
Bicomp demo
Lee Pomeroy (ELO, Yes, Steve Hackett...) Rickenbacker bass with his REV4 Bicomp.
Mark Bouras Hollywood Rare Guitars demo.
REV5 with MIX is now available!

In 2021, these are in slightly taller boxes (same height as Beano Boost, BART Sunface, small comp, etc) for cleaner internal copnstruction.

We have a new version starting in 2017 of the BiComp with 5 knobs in a row (with MIX and ATTACK knobs) and the INPUT, OUTPUT, and POWER jacks on top. They are wider than they are tall, like the KOT, switches are wider apart for easier stomping.

Rev5 circuit- MIX control available in 2016!

In April, 2013 we came out with REV4, which improved the COMPROSSOR (left side of BICOMP) circuit. Mike had been playing in a band for a few years, and noticed that SOME pedals on his board would not drive a load well, they would get dark and dull, due to a bad (high) output impedance. This is easily tested by running pedals into something like a low impedance volume pedal, with a switchable buffer between them. The ARDX20 with the delay level down is excellent for testing - when ON it's a great buffer, when OFF it's true bypassed. To test a pedal, simply turn the buffer on and off and listen for a change in tone. With most pedals, like our Chorus, Juicer, etc, there is no difference - they can drive the signal to your amp through long cables or volume pedals no problem. But the Comprossor sounded dull when the buffer was removed. The original Ross, Dynacomp, and all the other Ross clones do the same exact thing- they really need a buffer after them to sound good.

Also these pedals don't have a very loud output, especially when you hit them hard, for example with humbuckers or a boosted signal. One other problem all these pedals have is phase reversal - they flip the phase of your signal when you turn them ON. This may not be a problem for most people, but if you split your signal and combine it, or run into two amps, the out of phase signals will cancel and you will get a VERY thin sound. Also, for use as a clean boost, there was too much compression even with the SUSTAIN pot all the way down. So we reduced the minimum compression amount, without changing the maximum amount. Now the pedal is more usable as a clean boost, and also sounds great left on all the time as a tone sweetener/buffer. It's great stacked into dirt pedals, chorus, vibes, etc now. With these problems fixed, there is no need for a blend knob, you should be able to keep your pure tone without the need for additional circuitry.

All of these problems are fixed in the REV4 circuit -

  1. Excellent output impedance for a clearer tone with no signal loss or need for a buffer
  2. More available output for boosting your amp
  3. No phase reversal
  4. Less compression available

Here is a good article on the REV4 comp from Tone Quest Report : Tone Quest 2013 article

Rev5 circuit

This is pretty much the same as REV4 with the addition of a MIX control, which can go from full dry (no compression) to full wet (same as REV4). Mixing in dry gives you more of the attack of the note, which is compressed away normally, if you want to hear that. When set at full dry, the pedal becomes a clean boost/buffer pedal and makes pedals after it sound really great, with more presence. .

We also offer the USA 12V power supply for a little more headroom, good if you run a hot signal into the comp and highly recommended.

Here are the optional power supplies for overseas:

Ryck toggle option (Juicer high cut also shown)

The Dynacomp and Ross circuit is not very bright, to keep white noise down. But sometimes it's nice to have a bright trebly tone, as heard on Rickenbacker guitar's built-in compressor. Looking at the Rickenbacker schematic, it's about the same as the Dyna/Ross except it allows more treble for that jingle-jangle sound. We decided to offer this with a three-way switch so you can get just the amount of treble you want. One position is the normal Dynacomp/Ross value for the normal comp tone and low noise. The second position adds a bit more treble and just a touch of noise - this may be great to use all the time with a dark guitar like a Les Paul with high output pickups. The third position is twice as bright, close to the Rickenbacker setting, for a sound that really pops, with a bit of noise that you won't notice till you stop playing, if at all. We can put this toggle on any of our new CompROSSor pedals when ordered, or we can add it later on which costs a bit more as it's more work to add it after the pedal is built.The Treble boost is only on the WET (compressed) sound of the REV5, the dry sound mixed in will be normal tone.

Juicer HIGH CUT toggle available for normal, dark, or very dark. Great on bass but usually too dark for normal guitar tones.


We also have some in black as an option:

5 of 5 Bi-Comp Rev 5, (Hi-Cut / RYCK toggle / 1979 RCA) January 5, 2021
Reviewer: Dave Andrews from Bucks, UK  
Hands down, the best compressor(s) I've ever used.
The Bi-Comp brings forth the magic, and your guitar literally feels alive.
When I first plugged in, I thought I'd over-ordered, - because the Ross side just covers all of my Telecaster needs.
But I've now discovered the joys of the Orange Squeezer with a Strat and a Tele, and it's been on for days.
Everything you could ever need - and much more - from one compressor pedal.
You can't buy them off the shelves, but they're absolutely worth waiting for.
. . . So forget about snobby advertising campaigns, name-dropping musicians who passed away in '79 - and prices so high that you have to pretend that your mass-produced new boutique compressor is amazing . . . when it isn't really fit for purpose.
The reason Analogman pedals sounds and feel like the real thing, is because they are the real thing.

5 of 5 Best Compressor Pedal Hands Down! October 13, 2020
Reviewer: Stephen Leiweke from Nashville, TN United States  
As a session player, I've owned a lot of compressor pedals.  I have a couple that have been my favorites for some time. But they have always left me wanting a little more, or that special thing I couldn't put my finger on.  

I received my Bi Comp Rev 5 today and spent an hour with it tonight in my studio.  I am blow away!   There are so many useful settings and features,  my old compressors with be looking for news homes very soon.  

My deepest thanks to everyone at Analog.Man!   You guys are making the best pedals in the world!

5 of 5 Perfect October 16, 2018
Reviewer: Mark from Marietta, OH United States  
Hi Mike,

I got the Bi-Comp in the mail, today.  I’ve played around with it for a couple of hours, this evening, and I love it.  Covers all of the bases, compression-wise, for me.

I play Gretsches with Tv Jones Classics and Brian Setzer signature pickups, which sound great on their own, but I also play in a band where the other two guitarists play Telecasters, so it’s hard for me to cut through.

I’ve tried the MXR Dyna Comp (block and reissue), and played a Janglebox the last two gigs.  The Janglebox helped, but the Ross side of your compressor is what I’m looking forward to using at my next gig.  Nice, loud and clear.....not squished like the others.  I am having fun with the OS side and the Ryck switch, too.

Best compressor I’ve ever owned...AND, been able to play in a band setting.  Well done!

5 of 5 Wouldn't want to be without it December 9, 2015
Reviewer: Gavin from England  
These comments are for an earlier model that I bought in 2005. If I had to choose just one pedal to use with my bass, this would be it. Does exactly what I want it to, without taking anything away. The new revisions really must be exceedingly good!
