I use ink melting to apply designs on the enclosures.
Ink melting is an unpredictable process, you can only ‘feel’ or guess the results as you are applying the design.
Imperfections and small quirks appear in different places, color and contrast of each small portion of the design depends on different casting patterns of the aluminum enclosure.
Each time it’s a fight between me and the process, each time it’s a surprise. Each result is slightly different and it’s the main reason I don’t move to a more efficient design application method.
My pedals are all about quirks and their ink melted designs are an irreplaceable part of their weirdness.
