Cryogenic Resonance Restoration™

극 저온처리 Cryogenic Resonance Restoration™/ CRR™

대부분의 악기는 만들어지는 과정에서 일종의 스트레스를 받으면서 각각의 파트는 강제적으로 만들어지므로, 그 악기만의 울림을 제대로 갖추지 못한다.

악기의 관과 톤 홀(tone holes)은 사이즈를 늘리고 벨은 꼬아지며, 각 파트는 마지막 땜질로 악기로서의 모양을 갖게 된다. 이런 과정 속에서 금속은 스트레스를 받게 되며, 분자구조가 불안정적이게 된다.
CRR™은 -156'c의 극 저온상태로 악기를 냉각시킴으로서 불안정적인 분자구조를 규칙적이게 만들며
악기가 가진 고유의 울림을 극대화하여 최적의 상태로 만들어 준다

연주자들은 자기의 악기가 모든 음역에서의 좋은 음색과 좋은 음정을 갖기를 원한다. 그리고, 악기가 피아노시시모와 포르테에서 갈라지지 않는 다이내믹과 음정 문제에서 정확하고, 울림 있는 사운드를 원한다. 극 저온처리는 그 동안 의료계통에서 많이 사용하고 있었으나, 미국이나 일본 등에서 오디오, 스포츠, 악기 등 대한 극 저온처리 연구 및 활용이 활발하게 진행되고 있다.

Boss DM-2 Delay pedal

Boss DM-2 Delay pedal
  • Controls: Repeat Rate, Echo, Intensity
  • Connectors: Input, Output, AC Adaptor
  • Input Impedance: 470kΩ
  • Output Load Impedance: over 10kΩ
  • Residual Noise Level: less than -100dBm (IHF-A)
  • Delay Time: 20ms-300ms
  • Recommended AC Adaptor: ACA Series
  • Current Draw: 11mA (DC 9V)
  • Dimensions: 70(W) x 55(H) x 125(D)mm
  • Weight: 450g

there are at least 3 different versions of this circuit. The first DM-2 version was using the MN3005 BBD and the MN3101 Clock Driver IC (PCB marking: ET5214-510).

Later they changed the clock driver to MN3102 and the BBD to the low current version of the same circuit, the MN3205 (PCB markings: ET5214-510A and ET5214-510B). The MN3205 is a little noisier, but it generates less distortion (only 0.8% compared to 1% for the MN3005).

ICs, transistors and diodes used in the Boss DM-2 Delay:


























  • IC1: uPC4558C or JRC4558DD (dual operational amplifier)
  • IC2: NE570N (compandor IC)
  • IC3: MN3005 or MN3205 (4096-stage BBD)
  • IC4: MN3101 or MN3102 (BBD clock generator/driver)
  • Q1-Q4: 2SC732TM-GR (NPN silicon transistors)
  • Q5: 2SK30ATM-Y (N-channel JFET transistor)
  • Q6, Q7: 2SC945-P (NPN silicon transistors)
  • D1, D2, D5: 1S2473 (switching diodes)
  • D3: RD5.6EB3 (5.6V Zener diode)
  • D4: RD11EB3 (11V Zener diode)
  • LED: SLP 135B (red LED)


The Boss DM-2 analog delay pedal was sold from 1981 to 1984 and is still sought after thanks to its warm, natural sound. Produces a delay time ranging from 20 to 300 milliseconds, and has 3 knobs (Repeat Rate, Intensity and Echo).

Boss CE-2 chorus pedal

Boss CE-2 chorus pedal
  • 2 Control Knobs: Rate and Depth
  • Connectors: Input, Output, AC Adaptor
  • Input Impedance: 470kOhm
  • Signal/Noise Ratio: more than 90dB (IHF-A)
  • Output Load Impedance: over 10kOhm

  • Current Draw: 9 mA (DC 9V)
  • Weight: 400 grams (0.88 lbs.)
  • Dimensions(mm): 70(W) x 55(H) x 125(D)

The circuit is designed around the MN3007 1024 stage BBD (IC3) and the MN3101 clock driver (IC4). The input and output circuits use a uPC4558C IC while the LFO is made with the help of a TL022LP op-amp IC.

ICs, transistors and diodes used in the Boss CE-2 chorus:


























  • D1, D2, D4, D5 and D8: 1S2473 or 1S1588 (switching diodes)

  • Q4-Q8: 2SC945-P (NPN silicon transistors)
  • Q9: 2SK30A-Y (Silicon N-channel junction field effect transistor)
  • LED diode: SLP-135B


Adjustment procedure:

Turn the Rate knob fully counterclockwise (min.) and the Depth knob fully clockwise (max.). Feed a 200Hz, +3dBm sine signal into the input. Connect an oscilloscope to the emitter of Q3 and turn VR3 until you'll get a centered operating point (a symmetrical sine wave, equally clipped at top and bottom).

The Boss CE-2 is a great analog chorus pedal from the late 70s and early 80s.
the marketing of the CE-2 was stopped in November 1982, but the pedal was still produced and sold at least until 1990. Even though it's no longer in production there are thousands of these pedals being used by guitarists all over the world

    • D2: RD5.1EB-3 (5.1V 500mW Zener diode)
    • D3-D8: 1S2473 (switching diodes)

    The Boss SD-1 Super OverDrive is a pedal with a simple design, using only one dual operational amplifier (uPC4558C) and 6 transistors, with an asymmetric overdrive circuitry for a classic, natural tube amp growl. It generates the warm distortion of an overdriven tube amplifier while maintaining the subtle nuances of a guitar player's picking technique.

    The schematic is nearly identical to the classic OD-1 OverDrive, the only major difference is the tone control circuit. The design is simple and easy to follow: the guitar signal is buffered with Q5 and enters the first half of the uPC4558C dual operational amplifier. There are 3 silicon diodes in the negative feedback path of the op-amp. Two diodes are in one direction and only one in the other. This arrangement produces asymmetrical soft clipping -- one side of the waveform is clipped more severely than the other. The tone corrector and level control circuits are next. The signal finally exits the circuit after the output buffer made with Q6. The bypass circuit uses a classic arrangement with 2 JFETs (Q1 and Q2) serving as solid-state switches and a symmetrical bistable multivibrator made with Q3 and Q4.

It has 3 potentiometers for level, drive, tone control and a switch for selecting two modes of operation. When set to the OFF position the sound is similar to the OD-1 but in the turbo mode it generates more gain and distortion.
