Hi Guys,
I finished my Focus build last night and very pleased with what it can do. I've only been building pedals for the last 6 months or so and not really had any problems apart from accidentally using a 100k resistor instead of a 100r once so just after a bit of guidance.
It does seem to generate a lot of hiss at higher level/mix combinations than I would expect. Nothing massive but I would definitely need to use a noise suppressor its that noticeable. I haven't put it in an enclosure yet as I'm in the middle of a house move and my pillar drill etc are in storage so that might help, but wondered if anyone else has made one and noticed this too or if there is something wrong with my build? Maybe a noisy IC?
I've used OPA2134 from farnell and Wima/Nichicon caps. The only thing that are cheaper are the .22uF Electrolytics on the board and switching I used were cheaper JB capacitors from Tayda but they measured up well within spec.
Any thoughts?
TIA
