Finally Merlins Glassbower has been given a new PCB without VU-meter – which was making way too much noise when switching the LEDs despite the chip beeing a low noise version. Its version 1.5 now. If you want to build a boost 27dB without OpAmps check it out here: Merlins Glassblower V1.5 PCB The ROG Umble […]

The long time of silence at least has been interrupted. Here we are presentiing new stuff: The Kittenqueen – based on the Katzenkönig The long announced 3-band parametric EQ in the full control version.
Read some interesting news about the Modular Looper project. There is a new 3-band parametric eq for you to build. Its intended as a tone control to be built into an effect. There will be a standalone version as well.
I’ve been busy building prototypes, creating build instructions, sourcing parts and programming throughout the last weeks. Now i want you to see how a sandwich is done: How to make a sandwich This is not as funny as it sounds because its a major step to success. If you do something wrong it just […]
Read some interesting things about graphic and parametric equalizers in the new knowledgebase-article. Also there is a new DIY report on the same topic Equalizers.
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.
In the music environment nothing can be done without EQs! This starts with simple tone control and ends in the endeavour to simulate complex loudspeaker cabinets. 5-band graphic eq This one is using a special chip to reduce parts count and therefore space. It could also be done using OpAmps but I […]
Graphic EQs Graphic EQs are named so because of the fact that every frequency band is represented by a linear potentiometer and they are aligned next to each other. Looking at all sliders at once you see how the frequency attenuation and amplification looks like over the whole band. 5 band Graphic EQ Parametric […]
