With the Budda Om Overdrive guitar pedal, you won't have to worry about your guitar tone not being able to cut through the mix. With plenty of gain provided in this tight compacted box, you get a pedal perfect for anything from an old-school crunch to mordern fuzz. Put the Budda Om Overdrive guitar pedal in your signal chain, and you'll notice the jaw-dropping difference it has on your amp. The classic 3-knob user interface focuses on the EQ while giving you organic control over your overdrive tone. Check out the Budda Om Overdrive guitar pedal for that missing ingredient!
Tag it as working. I had to play with Tone caps (Really Really bright) and used a 4558/TL072 until I come across a LF353. It had quite a bit of noise but I think it may be long leads and crummy power supply at the bench. Thanks for all the great work!!! Have a Merry Christmas!
ReplyDeleteawesome bro. looking the the input cap, yea i can see that it sounds bright. listening to the videos of it i figured that i would be wrong, but guess not.
DeleteSo been playing with this all morning and here is what seems to be good to my ears as well as being versatile. Input cap (220pf) to 47n, gain cap (220pf)to 22n, 47n to a 100n, 1n to 1.8n, 5.6n to 6.8n, and 2.2uf voltage filter to 47uf. This seemed to reduce voltage noise, still maintain a good treble boost to thick tones in the tone sweep. It really has a unique voice to me so it is definitely worth tinkering to get it to sound good with your own amp! Thanks again for all the killer work!!
DeleteNice layout. I love these kind of knobs . Does anyone know where I can buy them? I tried to find them on Mouser but had no luck
ReplyDeleteLooks like Digi-Key has them in stock:

In the schematic I saw in the forums your 1nf is a 1uf. Is the schematic wrong or does it not matter much to the sound of the circuit?
ReplyDeleteThat does indeed kill a lot more highs. There is vey little low frequenciens getting in to tone control and recovery buffer.
DeleteSwap it for 1µ. Should work way better. I'd personally up the input cap as well. 220p is quite idiotic in that position.

Definitely makes a big difference. There is a couple other things that are confusing looking at the board and the schematic.... Mainly C6, C9, C10 and C11. Not sure if there was shuffle of some caps, one omitted or if it even makes a difference. (to be clear...most things look confusing to me LOL)
Deletezoomed into the schematic again, i think it is a 1uF, just hard to read and thought it was 1nF. i made the correction and updated the layout.
DeleteOk, for what it is worth, I had a little play around with different IC's, transistors and input capacitors. And barring one further adjustment (I still get a little high-pitch squealing at max gain), I'm happy with 18nF for the input cap, MPSA18 for the transistor (tried BC550, 2n2222, 2n3904) and the LF353 op-amp (tried 4558/9, OPA275, TL072, 5532.
ReplyDeleteA nice creamy overdrive to slight fuzz-i-ness pedal.
Cheers,

Mine worked for quite a long time (a month or two) and now has developed a really high pitched squeal when gain is cranked? ...
ReplyDeleteDon't bother. It whistles, sounds weedy and either muddy or trebly.
