200th Overdrive layout! I seem to be on the streak with Tubescreamers. This one also marks a special moment. In addition to this being 200th OD layout, i finally deciphered the original schematic which is very annoying to read (all 7-series schematics are). This one is also our first layout for the this series of … Read more
This puppy is basically another TS9, but it has clipping and gain options on “mode” switch. Modes are TS9, +, Hot and Turbo. Latter one acts as a diode lift, but adds a lot of gain. The switch is 2P4T rotary. Original unit has 250K dual gang pot for gain, and for some reason it … Read more
Hehee! Couldn’t help myself. It is in reality a TS9 🙂 If you want it 1:1, then use TA75558 and 2SC1815 transistors (mind the pinout!). You could of course build it with JRC4558D and check the output resistors to make it 808.. I still thought we needed at least one more Soundtank to our library. … Read more
I used a quad opamp to keep the size down, so this should fit in a 1590B. Solo Switch is a second stomp to give you a volume boost when soloing (funnily enough) and only a SPDT stomp is required for this, but use a DPDT if you want LED indication showing the “channel” you … Read more
Incorporating couple of cool ideas, here’ one from the man, Pink Jimi Photon. Note that the master volume control is optional and anything smaller than 1M will probably hurt the output level. The level should be within reasonable limits without it. Here’s the original description: Positive it’s been done a gazillion times before. but one … Read more
You bassists on here are pretty speedy builders, so who will build this first? :o) At 22 x 14 this will fit in a 1590B if you file the sides down a bit, but with it being a two stomp effect you’ll probably want to put it in a 1590BB or at least a 125B … Read more
Doron! I think you meant this one and not the MSL 😛 To add a few words, the clipping diodes are placed neatly where you can easily take them on the switch and have your way with them. I would probably go with three position two pole switch and have the middle as diode lift, … Read more
Got an early 90s unit recently, the chinese reissue with JRC4558 chip. I’m still really surprised how good it sounds. So i do think this is very neglected and underrated pedal. I’ve added polarity protection diode and pulldown resistor for the input. The chip is stated as KA4558 in the italian reissue schematic i found … Read more
Edit 31.7.2016 – There was still one crucial error on the layout, which made the board defunct. Fixed and tweaked a few things around to accomodate the polarity protection etc. *Should* finally be safe to build.
Request. Hmmm, I’m spotting a few similarities to something else here! :o) But true bypass switching and so without the famous buffer. It does have a lot of changes though and some of them will undoubtedly make a difference and affect the final tone, so worth a build for you Klon fans. Note the two … Read more
