About This Listing

KAM CHAINSAW distortion pedal / JCM 800 Emulator 


We have produced a 2nd batch of 50 Chainsaw units with hand signed serial numbers in the back. The serial number you will get depends on when you purchase. We will start from 1 and go to 50 in order of shipment date.  

The first batch which was released a few years ago was also 50 units but they did not have individual serial numbers and there was a generic sticker on the back. There has been a lot of requests about Chainsaw, so here it is again!

Chainsaw is a complex pedal with about 100 electronic components used in its construction.

There is a video comparing JCM 800 and Chainsaw on YouTube:

JCM 800 Emulation

After Kenny Olsen (of Kid Rock fame) used Chainsaw for a while he told us; “ When I set my fender amp on a clean sound , Chiainsaw can make it sound just like a JCM 800”

Although there was no intention to design chainsaw to sound like JCM 800, the circuit design goals were for similar attributes including:  

-       A crunchy and aggressive sound with a lot of gain

-       Ability to retain a lot of bass in the sound even at high gain settings

-       Ability to easily produce pinch harmonics

The sound of the pedal without using any amps (e.g. directly fed into a mixer) is interesting, dynamic and very playable. When feeding it to a clean channel of a tube amp with good high and low frequency response, you can adjust it to produce a sound similar to JCM 800.  

A number of artists have been using Chainsaw. Including Rick Olsen(Berlin), Mike Vescara (Obsession), Kenny Olson ( Kid Rock), Ethan Brosh, Hugo Ferreira (Tantric).

Chainsaw  Sound

KAM Chainsaw is an aggressive sounding guitar distortion pedal with each knob having drastic sound shaping range, enabling the unit to produce sounds from seventies to ultra modern flavor, all with an added hard edge.

Sample settings

Here are some sample settings as starting points. Remember that your playing style, amp, and cabinet play a large part. The drastic range of the knobs helps you fine tune the sound to achieve the results you need.

Numbers for settings are in “Clock positions”, so “12” means the knob is pointing up, exactly in the middle of its movement range. 

Style:                                High       Middle          Bass          Gain

Djent                                  9               9               4               12

Classic Rock                         3              11              4               11

Death Metal                         4               7               5               3

70’s Hard Rock                   12               2               3               11

Nu Metal                             3               9               3               12

Heavy Blues                        11             2               3                5

Studio / Stage use

If you play at larger venues which have stage monitors, you can actually play without an amp and feed chainsaw directly to the mixing board.

Chainsaw can be fed into a recorder directly as well as used with guitar amps. To achieve this Chain saw can produce a high level of output. If you are using it with an amp, the “level” knob set at a “9 o’clock” position can produce an output level similar to an electric guitar. This is a good starting position.  Don’t turn the output too high when using an amp to avoid possible damage to the amps input circuit.

The unit can be powered using a 9 volt battery, or a standard 9 volt effects power adapter. To conserve the battery disconnect the input cable when not in use. Even when the effect is switched off, if the input cable is in place battery will be used at a low rate. The circuit is always receiving power so that when the effect is switched on from bypass, there would not be a clicking sound in your music.

If you use the unit without a battery inside, make sure a piece of tape or a small plastic bag covers the battery connector terminals so that they don’t accidentally come into contact with any metal inside and create a short circuit.
