Hello everything well? I set up a pedal of Ibanez OD855 Overdrive , I set up and I revised all the connections and pieces. Didn't the pedal work, did anybody already set up this pedal?
Hi, Sorry for my bad english, but I´m from Germany. Well, I´ve built up that stompbox 2 times but it doesn´t work, yet. I´ve checked all soldierpoints and changed every part. There´s no signal coming out. Does anybody has some checkpoints where I could controll voltages etc.? I´ve tried it with different kinds of transistors and diodes. For the original 2n5088 I use BC 549C, BC 109B or BC 109C For the original 1n34a I use 1N823, BAT41 or AA119 (=1N60)
Hi, i´ve checked some other schematics off the Ibanez OD-855 and I found 2 points that are not right. There are 2 resistors connected to ground. That´s wrong. I think you´ve to connect them to +4,5V Vr. You can find the first 100K resistor at the third IC connector and the second 10K resistor at the fith IC connector. I had the problem that the was absolutely no signal comming out. Now I can hear something :). But perhaps you can find some more of wrong points in the schematic. I´ve compared the schematic with this one: http://topnet.com.au/~hairbear/OD855_schem.gif
