I’ve used Mad Professor’s Blueberry bass overdrive for ages, but some features have always bothered me. Firstly, the volume pot is way too sensitive. Plus I’ve never opened it beyond 9 o’clock, so less would be enough. Another issue is that I don’t like it how the “nature”-pot works. I’ve always missed just a regular tone pot.
So, once again I turned the soldering iron on. Roger Mayer Voodoo-1 is a quite nice overdrive pedal for guitar, and the Voodoo Bass is, well, guess. I really don’t believe in watching Youtube-videos and trying to find the suitable pedal for your needs as there is so many things affecting to what you hear starting from your lame computer speakers. So, only knowing that it’s just a low-gain overdrive for bass as well as for guitar, I started building. The layout is as follows:
As I had all the needed components in stock, there was nothing special in this. Except the pots. Gain seems to be C50k , but as I didn’t have any reverse logs, I needed to put a A50k in there. So the gain-pot is not working as it should, but it still can be controlled well. When turned counter-clockwise now, this is almost like a clean boost. Just a hint of a overdrive here. Gain scale is working really well, and in the clockwise end this is a real ear harrowing grater. Fuzzy distortion is coming from doors and windows. Tone is just what I want it to be. You cannot either dampen or sharpen the tone effusively, but still there is enough scale for me. Fitted OK in 1590B:
I originally put a 2,2K resistor for the orange LED, and it caused third-degree burns to my face. What a searchlight! Ended up to 15K and I am pretty sure that it’s still well enough in stage, as I still cannot look at it straight. After a little wordplay I’ve got a new overdrive for my bass rig.
