There have been a few of these questions during the last months. So here is what you can do if you want to use a NoPe switch at the control outputs of an ES-8 or superswich or whatever unit is out there that hav 5V control signals to be programmed.
Also if your control unit does not put out control signals and instead uses a switch its easy as one side of the switch needs +5V from the circuit and the other one then connects to the input of the NoPe.
There is an electronically good and a bad solution (of course the bad one is faster to achieve) but we focus on the "good" one here.
This is what you need to do:
Replace R3 (10k) with 100k
Replace R1 (68k) with 1k
lift (cut off) pin 3 of IC1
Connect GND of controller to GND of Nope
Connect Control of Controller to SW. (mind the dot!) its the pad next to C3
For reference here is where the bits and pieces are located:
When a client approached me to silence his Tonehammer amp I took on the task. Here is the short story what we did.
There are two cheap fans 50x50x10mm used in the stock amp. Although they are not super noisy but due to their size and rpm needed they make an annoying pitched noise.
This is whats in there:
So we took them out and replaced them with some high-end silent fans 60x60x25 and its making no noticeable noise now. To fit the backside fan we had to design and 3D print an adapter which allowed us to use the original holes to mount the much larger new fan.
This is how it looks after the mod:
Feel free to contact us if you wish something similar done to your amp. (Of course warranty will be void after the mod but we send you back the original parts to undo the mod - just in case.)
This is the story of how this handy tool came into existence.
Once upon a time there was a pedal builder soldering effect circuit after effect circuit.
Most of the builds were running out of the box - soldering finished, guitar to in - amp to out - there was noise!
But occassionaly there were effects that refused to work - even refused to get going after a serious amount of time staring at them or fumbling with the wires, looking at solder joints etc.
And there it is - there is this box. Its usually hidden in a cabinet but from time to time you take it out, look at it - put the piece of your most recent frustration into it - and put it back.
You know this box exists. Sometimes you dream about it. But you rarely open it up and take something out.
You know you are able to fix it. You know it will cost a significant amount of time looking at it and setting up the equipment for testing if you want to dig deeper into it.
So you usually let it go and this box will get filled to the brim with frustration.
I also have this box. Honestly when you are developing new pedals - like I do - this box is not only a box it becomes a cabinet itself.
I made some thoughts what it is that is hindering me to just pick something from time to time and fix it. I quickly came to the conclusion its the testing setup you need (signal generator, oscilloscope, multimeter, power supply, wiring...).
I am well aware that there already are quite a few testing rigs out there you can use. But I wanted something different.
I wanted something that is formed like a pen and that I can point and use like a soldering iron. And it should have the most needed features on board. I did not want any separate parts and pieces cluttering my workspace, just the power supply, the effect in question and the pen.
And I made it. It was a long way to go. There were six! (6) revisions from the initial design. Its my first SMD design and I had a steep learning curve and it took more than EUR 600,- and 9 month for this:
I wanted other people to use it as well, so it had to be cheap but great in design and usability. Here are the features:
Tracing of existing audio in a circuit – works as amplifier and loudspeaker
Signal generator feeds audio into circuit and tracer checks existence in circuit
Signal generator only – when the circuit is already plugged into an amp (not recommended)
Here is the trash pile of all the prototypes I did.
And here you can see all the revisions of the pen that were made through the development process:
You want to know how to use it?
Here is a video I made. Its a little trashy but you will get the point 🙂
We have been working hard rework the website to bring it to current website standards usable on mobile devices as well as on big screens. Information is more structured available now and - it looks better 🙂

As of Jan 1st 2019 Deutsche Post - along with a lot of other carriers internationally - does not allow to ship goods in letters anymore. A new product has to be used which is a minimum of EUR 3.20 / 3.80 for shipping.
New kid on the block: Merlins Small Time Delay (with tails). This is a nice delay circuit with tails - meaning that even if you switch it off the signal trails out (repeats) and newly played notes dont have the effect.
