Lovepedal HiVolt

I've got the original schematic for the love pedal hi volt which is a mu-amp cascading JFET design only problem is this is the actual love pedal schematic from sean so it needs to be re-drawn I believe if I want to share and post it which I could use a hand with

..has a free schematic drawing program which is intuitive and easy to use. Or you could email me the schematic and I'll redraw it. Pm me if you're interested in the easy option

Slight revision (connected "hot" ends of treble + middle EQ pots to last opamp inverting input, EQ pot lug numbers labelled)

Hello!
I've just finished HiVolt, using the excellent layout from Effectslayout (https://effectslayouts.blogspot.ro/2017 ... 0814985595), but it didn't work. I found that the problem comes from the power supply part, which is wrong on the schematic.
So, you must disconnect 1N4001 diode from the pin 7 of MAX1044 and connect it to pin 8 (as I saw in many others schematic).
Now it works, but not as in videos. It hasn't a tight sound. It has a muffled sound. Maybe there are other errors in the schematic? I compared the FET part with BSIAB2 and some values are very different. The most strange part for me is the 33nF+10K+3.9K filter. What is for?
The tone pots has a weak action, especially for the mids.
Thank you!

My bad on the voltage doubler - I should have spotted that.
The EQ is weird, but pretty sure it's accurate

The 10K+3.9K seems strange because it is easier to put a very common 14K or 15K insteadNocentelli wrote:My bad on the voltage doubler - I should have spotted that.

I will make some sound tests before the filter. I biased the last FET at 8V (half of the power supply).
Anyway, maybe someone which has the pedal can recheck the values. For example, the 820K in HiVolt is only 82K in BSIAB. I don't have many electdonic knowledges...

i've built it twice using the posted schematic (with a corrected charge pump) and it doesn't sound anything like the original. the distortion is very ugly sounding so i think that there are a few more errors with the re-draw besides the charge pump.

well, Jesse sent the schematic and i checked it. the only other difference besides the charge pump issue is that the 820K resistor at the gate of the 5th Jfet is an 882K one as per Sean's schematic. other than that it matches it.
i've tried both an 820K and an 82K but to no avail. this one matches the one that Jesse sent me.

After I made the link that you suggested about the pin 3 of the mid pot, mine works almost OK. The main problem is a huge noise (but, as I remeber, BSIAB is noisy by default). Moreover, the mids are a little strange, like a fixed wahjohnk wrote:well, Jesse sent the schematic and i checked it. the only other difference besides the charge pump issue is that the 820K resistor at the gate of the 5th Jfet is an 882K one as per Sean's schematic. other than that it matches it.

I added link in the layout from here: http://effectslayouts.blogspot.ro/2017/ ... -volt.html...in the comments you can read exactly wherehozy31 wrote:Hi gigelmargel, what was the link you added to lug 3 of mids pot, i can't seem to find any mention of it?
Good luck!
