Jekyll n Hyde Serpa Custom sent out to Jeff H. in San Diego CA. 2500volt meter. That’s gonna be one heck of a power supply! (Just kidding) …the JnH boxes only need an 18volt supply. Jeff doesn’t have to tell anyone that though… 😂 #modularsynth #eurorack #sandiego #modularfuzz

Jekyll n Hyde dual filter “Serpa Custom” off to K. U. in Chicago IL. I always warn about the Serpa cross resonate feedback mod.l can throw you off. How if it’s engaged it will make things “odd” and behave in an unexpected way depending on what’s being fed into each filter. …Well, when testing I spent some time trying to figure out why the signal sounded over distorted. Turns out I had the mod engaged 😂 #modularsynth #eurorack #RMLfx #analogfilter

So here I am making more holes… Jekyll n Hyde Serpa Customs… I will not pretend drilling 37 holes in a box (perfectly aligned) is an easy task. I prefer to do it un-rushed while listening to nostalgic electronic music. 🙂 #modularsynth #eurorack #modularfuzz

Two interesting b-stocks on the website. (RMLfx.com) …had an argument with the drill that ended in some minor scuffs. Got the bright idea I might be able to re-paint over the powder coating. The answer is yes you can but there are consequences. 😂 #modularsynth #eurorack #bstock #portland #guitarpedals

This EFC Retro shipped out to Kevin F. in St. Louis Missouri. First of our new laser cut panel. Been putting a lot of time to make these builds more efficient. The laser cut panels means a whole lot less drilling. Any imperfection drives me nuts. I can tell just by looking at a hole if it’s .025mm or less off sometimes. A lot like learning to listen in milliseconds. #modularsynth #eurorack #guitarpedals #portland

A very big meter indeed. This Jekyll n Hyde (Serpa Custom) dual filter box went out to John C. In Montreal Canada 🇨🇦 ...ready for the winter with analog warmth and destruction. Had to buy an extra large hole saw to make this happen. I should have a degree in hole making at this point! #modularfuzz #montrealcanada #modularsynth #eurorack #portlandoregon #RMLfx

Can we talk about helping hands? Throughout my journey in electronics I’ve always felt using them was like asking a drunk friend to hold something while you try and work on it. But over time my relationship with them has evolved. Here are some tips: 👉 first use a clamp to hold them in place. 👉 wedge a barrel jack on one end to make soldering DC jacks easier. 👉 use a dremel to drill through the little clip and arm, wrap a thick component leg or wire through and around the hole. 👉 Your drunk friend is now a reliable buddy that helps you consistently though out your day. 😁 you might already know these things but I’m sure someone can benefit from this advice. #themoreyouknow🌈 #eurorack #electronics #shopstuff #RMLfx @ Portland, Oregon

I may have lost 2 days figuring out how to fabricate meter glass with the #epiloglaser. Some of these old meters have beveled injection molded plastic/resin “glass”. The coverings need to lift high enough over the needles. The main issue was is the deeper I needed to cut the edges start to burn in changing the diameter of the “glass” (it’s not really glass). So getting the depth and the process down was time consuming. Can’t leave the laser unattended while cutting acrylic cause fire 🔥. More to the complications involved but that’s a bit much to get into. Eventually I got it down. So that feels good. #shopstuff

Jekyll n Hyde Serpa Custom off to Einosuke in Japan. Feels like wrapping up a child and dropping it in the mail. Coincidentally that was a thing in 1913-1915. You could actually ship a human child using the US postal service. 😱 or specifically no rules against it. So naturally people took advantage of that. Fun fact. Nowadays you can ship live bees 🐝 in the USPS! There’s a good gift idea for the holidays 🧐 #modularsynth #eurorack #modularfuzz #RMLfx #japan #portlandoregon

Hi RML, just thought you might like it
Hi, THE JEKYLL N HYDE DUAL FILTER BOX, I have a question 🙂 do I understand correctly that this filter can work normally in stereo mode and then both IN inputs are like L and R inputs, and in mono mode (we talk about M / S switching), two inputs are like two separate spaces (transistor and diode)? is there any more detailed description of the operation of this device? user manual ?
You should do a limited edition resin wood box! :D
Not only nice looking but practical.
