Description
The new Mu-Tron Opto-Mod, swappable technology allows you to change the overall ADSR (Attack, Decay, Sustain, Release) characteristics of your Micro-Tron IV. Â For many years, the performance of any given Mu-Tron III was based on the electrical performance of the photo-couplers which were used to give the devices their unique and expressive feel. Â Unfortunately, not all of these photo-couplers behaved the same and depending on what other components had drifted from their stated values, some units were magical and others were lackluster. Â Â With the new Opto-Mod modules, we are able to precisely calibrate every unit to the same Mu-Tron standard of perfection.
- We designed the “Gold” Opto-Mod to behave like the vintage Hamamatsu 0805a photo-coupler found in the vintage Mu-Tron III pedals. Â It produces a very pleasing, general-purpose “curve” which works well in all settings. Â This is the stock Opto-Mod that comes in all Micro-Tron IV.
- The “Red” Opto-Mod, has a slightly slower attack and decay time, which offers a longer “curve.” It is a bit chewier and is great for slower, swampy types of music. Â Also, in the “Vintage Mu-Tron pre-amp jumper mode,” the Red Opto-Mod can get a little grittier. Â This unit models an older Mu-Tron III which has drifted out of factory calibration.
- The “Blue” Opto-Mod has a much steeper Attack and Release and is more suitable for fast, “Jaco” style bass playing. Â If you like to play 16th and 32nd notes and your filter just can’t keep up, this may be the one for you.
