They make it easy to turn the knob with your foot. If you want more than one, you can add them to your shopping cart from the Accessories - Pedal Parts menu.
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.

Description Technical Specs
The Analog Man Mini Bicomp has exactly the same features as the BICOMP, just takes less real estate on your pedalboard. Many options, best for power supply use, not battery. Same size as juicer or small compressor.
REV5 with MIX control became available in early 2016!

Mini Bicomp is exactly the same features as our BICOMP, just takes less real estate on your pedalboard. Same size as juicer or small comp. Works on battery or 9V DC adaptor. We make the cases in-house for a cost savings. They are not all perfectly machine-drilled and silk screen labelled like the BICOMP, but have a hand-made appearance. The switches are a little closer together, makes it easy to switch from one compressor to the other by pressing both switches at the same time. Use the side of your foot to easily switch just one side.

For battery use, it's best to get the large BICOMP as opening the mini bicomp pedal often, can stress the wires as it's packed very tightly.

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

Rev4 circuit

In April, 2013 we really improved the COMPROSSOR 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

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 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. When set at full wet, it's a normal compressor like our REV4, Ross, Dynacomp etc. Mix is available as a trimpot on the circuit board of the Mini Bicomprossor.

RYCK toggle option

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 Rickenbacher 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 about the same tone as OFF, 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 probably won't notice. We can put this toggle on any of our new CompROSSor or Dynacomp 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.

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

Here is one with all 5 knobs, only the right VOL knob is for the JUICER side :

Here is one with 4 knobs (internal ATTACK) and a toggle:

5 of 5 It's a keeper September 15, 2013
Reviewer: Michael Hanney from Seattle, WA United States  
I've had mine at least 6 years and it's never been off my pedal board. Ross side with Tele, Orange Squeezer side with Strat. Set it and forget it. Always on one way or the other. Perfect.

5 of 5 Can't imagine there's a better compressor November 11, 2008
Reviewer: Lance�Newhart from Torrance,�CA�United States  
This was my first compressor.  Was a great way to hear both the Ross and Juicer flavors.  Found I was a Juicer guy but always had the Ross around for the occasional chord work.  If you don't know what compressor to buy, this is the one to get because it'll allow you to learn what different flavors of compression can be used for and you get to try and keep both flavors in a fairly small pedal in case you, like me, are finicky and might like one better today and the other better tomorrow.

5 of 5 Nice...really nice. April 28, 2008
Reviewer: Anonymous Person from IL United States  
Got the mini bi comp four days ago. Love it. Tried other higher end hand made pedals, and a few not so handmade, and this tops the bill by a large margin. Straight out of the box it is a great pedal, nice and quiet. The OS side is a perfect clean comp with hardly any noise; the ROSS side works great before a drive pedal. Can't say enough good about it! One thing, I did open it up to check out the battery changing and the pc board is attached to the back, so when you take the back off some contacts (which are all very well constructed!) will be stressed. This is the only negative I would give the pedal, and it is likely an unavoidable consequence of the size of box. Great pedal overall and the last comp I will likely ever need! If you're like I was, trying to decide to wait on the big bicomp list or just get this mini, then unless you NEED to adjust the attack and are OCD about it this pedal will do all you want with little twiddling of knobs, it does it out of the box just fine!

5 of 5 Get it>never turn it off April 29, 2007
Reviewer: Stew�Phillips from los Angeles/NYC  
Before I got this pedal I was using a Boss CS-3 and I loved it. I knew about analogman, but never considered the fact that there could be a better compression/sustain than what I already had... I was quite wrong. I picked up the mini to avoid the waitlist and threw it on my rig. The ross side sent the cleanest comp/sus into my 65 DR and made my ears swoon. The switch to the OS adds a very nice contrast(although the OS sounds much better with humbuckers IMHO and really adds an Steely Dan dynamic) This is a must have for any tube amp and will let you develop your sound. I crank the attack and sustain and just let the thing do the work. Check it out-Stew
