Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
It's a Marshall Guv'nor with different values for a number of parts, and the leds are in the feedback loop of the OP amp rather than put to ground. I'll definitely have to give this one a try... ^^
Built it, it's definitely a good one to me. The only thing is I have had to swap Bass 3 and 1, else my build would increase bass while turnnig the pot CCW.
Yep, working, but I'm having a strange streak of not getting one or more pot working the right way from the start. I've got about four builds with the same sort of problem. On this one, Treble and Mids pot start to "work" in the last 25% of their rotation. The first 75% doesn't do anything to the tone.
So, I had to go and check the pot values from an original unit and based on that; Treble is 10kB and Level is 100kA. Treble control got better with the 10kB, but the Middle pot is still acting as I mention above. The first 75% is practically doing nothing but after that it gets boosted dramatically. It's like a bumblebee in a glass jar :D
I have one of the BBE Blacksmiths which use this exact circuit. What would be suggested mods to "open up" the sound of this pedal? Right now it feels a little flat and congested.
I was going to put some different diodes in place of one of the LEDs for some even more assym clipping and do the suggested filter cap swap to a lower value.
Thanks all, and I need to say this is an incredible service that the admins and contributors are providing. Nothing but love.
Ok, so I put a 220uf in the filter cap spot, I think it made it a little saggier which is nice, and I swapped out the 2 LED's for 3 asymmetrical silicon diodes. It now clips more like I'd like, but I definitely lost volume. Full volume on the pedal isn't even meeting unity with my amp.
What's an easy way to up my volume? Is there a resistor value I could swap for a lower one, or should I swap the 100k level pot for a 50k?
Which classic is this based on?

ReplyDeleteCheers Rafael! I'll tag it right away.
