TRIM4 - UPCB
The Farndurk TRIM4 Utility Printed Circuit Board.
I designed this thing to take care of many different little chores. It's as utilitarian as a shovel. It's just a small PCB with a clever layout that allows me to install a number of components that provide any number of useful variations. Due to the way it's designed it can be set up so each component is totally isolated from the others, or it can be set up in a parallel configuration between ~blocks~, or in a series configuration, or even a series/parallel and commonly bused. The TRIM4 is a very unique, and ridiculouly useful little tool.
It can be used to mount various trim-pots. Now any combination of adjustment trimmers may be easily attached to pedals that have enough space to mount the (miniscule) TRIM4. As you can see it's just tiny! Yet it carries all the power of FOUR FULL SIZED POTENTIOMETERS when outfitted as it is in these pics. Now any control panel-mounted functions may be (instead) quite easily mounted on the TRIM4 and concealed inside.
I can mix-match different types of components and trimmers as well. The TRIM4 is cleverly designed so that many many different types of circuit board mounted components may be installed and connected using the TRIM4. Here's a mixture of two different types of trimpots.
The TRIM4 can also quite easily accept other types of components due to it's unique design. Here's a transistor socket mounted amongst some various sized trimmers.
And it can also accept other components on these transistor sockets so that you can easily swap out different parts without doing any soldering (such as capacitors to revoice your pedal!)
Here's some more SOLDERLESS installations of different components. With the TRIM4 it can be installed within a circuit to provide you with solderless swapping of clippers as well as totally separate solderless mounting of the transistors as well as separate solderless mounting of voicing caps, all at once! And TRIM4s may be used in "gangs" as well by istalling more than one TRIM4 inside the chassis and wired appropriately. Pictured here are (left to right) a transistor, a silicon clipping diode, a clipping LED, and an output capacitor!
Here's an entire row of micro-trimmers. They may be left isolated or some/all of then may be wired in series, or parallel, or series/parallel configurations. A TRIM4 could be used to adjust the brightness level of an LED array too (some folks like their LEDs a bit dimmer, and others like their LEDs to be LASER BRIGHT).
One of the COOLEST features of the TRIM4 is that if only one or two components need to be mounted on it, and there is little space available for the TRIM4 ... it can be cut in half!! I designed the TRIM4 to be able to stand quite easily on only one standoff. This makes it very small, and easier to mount within small spaces.
Components may also be soldered directly to the TRIM4 just like any printed circuit board. In this picture an entire two stage EQ is mounted on a TRIM4. One side has a fully adjustable High Pass Filter (for bass sounds) and the other side has a fully adjustable Low Pass Filter (for treble sounds). A full-on two-band EQ mounted on a tiny pcb! So a custom installation of a properly outfited TRIM4 could provide a complete TWO BAND EQ within some of our pedals that do not have room on the control panel for the necessary knobs and point-to-point circuitry within (such as some of our X pedals). It would also be a lower cost option to install an EQ system in some of our other designs such as the Model 8, it would cost less as an option because I wouldn't have to do any extra drilling, or letterstamping to provide the extra knobs needed to set up an EQ. The TRIM4 could be configured as a two band eq (or even a single low/high pass filter) inside of certain pedals at a much lower cost than having me totally design a new knob layout, drill the enclosure, stamp the letters, add the pots and the knobs and washers .. bla bla. This may even make way for me to reissue the Dyna-Q system as an internal mod that would be FULLY configurable! Now THAT'S exciting!
Here's another two-band EQ but this time the voicing capacitors are mounted in sockets so that you may re-voice the EQ to tune the equalizer to suit your needs precisely. The voicing caps simply pop out and new voicing caps simply pop right in, completely changing the response and tune of the EQ .. all SOLDERLESS!!
I ran off over 50 TRIM4s in this first run, here's but just a few. The TRIM4 will be with us from now on.
And finally you can get a comparitive idea of how miniscule the TRIM4 is, there it sits next to our custom black knobs and a pair of our handmade stainless steel flatwashers.
With our exclusive all new TRIM4 Utility Printed Circuit Board (*UPCB*) the sky is the limit:
- We're now able to offer more versatility than ever in many of our designs.
- By using three TRIM4 boards, nearly the ENTIRE set of controls and options in the MEGA9 could be placed totally inside of the chassis, making for a completely MEGA-STEALTH pedal! ALL of the settings could be done within the unit!
- We can also set up an EQ system within a given pedal that is totally adjustable AND completely revoicable!
- We can now place removeable transistors within an enclosure for some of our pedals that use them (such as the WFO, which uses FOUR transistors and the main PCB does not have the space to install a transistor socket .. let alone FOUR of them .. on it's surface). This would allow solderless experimentation by changing transistors.
- One of our CARMA compressors could be set up in a large chassis and reconfigured as a BASS COMPRESSOR by using the TRIM4 by allowing completely removable voicing capacitors mounted on transistor sockets.
- Or how about a totally knobless CARMA compressor! All four knobs can be replaced with four trimpots all mounted on a TRIM4.
- The TRIM4 will also, without any doubt, be used to calibrate the signal levels of our all new M3OA Hammond M3 output adaptor to allow setting of the line-level output signal while safely keeping those controls within the enclosure.
- And it goes on and on and on ....
So it may seem like no big deal, but as time goes on we'll discover many uses for the TRIM4 and I can promise you it will end up in many custom renditions of a number of our pedals!
TRIM4 ... GIT SUM!
