Jim Dunlop MXR Dyna Comp Pedal

Product Information

The parts in the design are not critical, you can use substitutes for the transistors (2N3904) or the silicon diodes (1N914). The only part which is not so easy to find nowadays is the CA3080 IC. The output of this buffer is DC isolated through the capacitor C2 (1uF). This C2 and R4 form again a high-pass filter with a cut frequency of fc=1/2πRC = 1/(2π x 1uF x 1MΩ) = 0.15Hz. This filter will DC-isolate the next stage without modifying the audio levels. The input resistance of the CA3080 inputs (Zin) depends on the amplifier bias current, looking at the "input resistance VS amplifier bias current" it can be seen that the Zin has a middle value of around 1M.

Walrus Audio has been making a bunch of really cool effects for the last couple of years, and the Deep Six is no exception. Compressors were initially used as studio recording utilities by engineers. Today, they are a necessary addition to the pedalboards of the everyday guitarist, and there are plenty of options on the market.While I find this can kill the expressive dynamics of rhythm playing if dialled up too high, it gives a great boost and definition for soloing, especially when paired with a good overdrive pedal (more on this later). The only control on the pedal is a speed control so it’s an easy ‘set and forget’ pedal. The downside is that it only has one control – so you won’t be able to tweak the effect like you can with other pedals. Of course, there’s a certain amount of crossover with the sensitivity control, in that compression level is controlled there. Bringing up the sensitivity will result in ‘squash’ as the sine wave top and bottom of the signal are attenuated or boosted, respectively.

This control also affects the way the release time works in the pedal, so you can also use it creatively with whatever type of guitar you are using for another compression flavor if you want. When opening the box for the Dyna Comp Bass, the first thing you might notice is that the power-adapter box is larger than the pedal itself. This mini-format compressor is about as small as one can make a pedal these days, and for a travel rig or someone who doesn’t want much more than a tuner onstage, the Dyna Comp Bass can speak volumes.

About MXR Dyna Comp

Or for simply sending a rounded signal to other effects pedals in your signal chain. To get a clean boost from the MXR, you want the Output to be fairly high, but the Sensitivity fairly low. You have probably heard this saying over and over whenever somebody talks about how a guitarist gets a certain tone. It can be frustrating for a beginner to hear this from more advanced guitarists because it isn’t practical or useful for a beginner (eg: you may not be ready to practice the type of bends that sound distinctly like David Gilmour).

Because there are so many different Fuzz pedals out there, I’ll list three options that losely match what David Gilmour has used over the years: Dunlop FFM1 Silicon Fuzz Face Mini The low frequencies area is dominated by the high-pass filters that place two poles on 3.1Hz and 0.15Hz creating a roll-off for the low harmonics. This filters will just remove DC-offset at the input and between stages, the audio band (20Hz to 20KHz) is not touched. It’s worth mentioning that the CE-2 is very overpowering and David actually had it connect to a dedicated amp so he could blend the chorus ampwith his non-chorus amp. Fortunately, the CE-5 has an effect level knob so you can easily control the level of chorus. The output level also has enough gain on tap that you can use this pedal as a super clean and focused boost for solos or hitting your amp harder. The MXR 102 Dyna Comp is a compressor effect guitar pedal, released in 1972 by MXR and rapidly becoming popular because of its price and ease of use. The electronic circuit was also used as a reference design on many other compressor effects like the Ross Compressor, T-Rex CompNova, Ibanez/Maxon CP5/CP9/CP10 and boutique pedals. This model is neither the most silent nor the most hi-definition piece of gear but it has real character and it's easy to find.While the things I outlined above are really only scratching the surface on how compression works and why it’s useful on pretty much any sound source, here’s a list of great guitar compressor pedals you can utilize to enhance your tone and increase your guitar’s sustain.
