I was just looking at the schematic for the Lead Solder Overdrive. I see it uses three TL072 ICs. In two of the TL072s the second stage isn't used. Why didn't they use two TL072s instead?

I think this will do for now! I don't want to bore you... I was surprised when I built a Vemuram Karen - The Kadundra here - at how much I liked it. It's a really good aggressive, vaguely Marshall sounding OD. And again I felt that perhaps it had too much low en oomph with no way to control it...

The Perplexed layout seemed to generate more interest than anything else I've posted so I though I might post this one. This has become a firm favourite for me. I love the sound of this fella! I had been avoiding JFET ODs for ages because of the biasing thing. But recently because of Chuck's...

Probably sounds more exotic than it really is! Kiste is German for Box, and Steine means stones, or maybe even rocks. So you get where I'm going with this! As is my wont I have added a bass pot which I think really makes a difference for this one. I have also pointed out the mids cap which was...

I can't remember if I've posted this anywhere before, but I really like it! It's based very clearly on the Wampler Plexidrive which I was surprised by. It sounded better than I expected. (Sorry Brian!) I did find the cap on the source of Q2 was a bit big which for me made the bass a bit fizzy...

I built a DAM Sonic Titan ages ago from the Tagboard Layouts layout on Vero. I liked it but it never became a mainstay. Recently while looking for the Music Man preamp schematic I found a new schematic for the Sonic Titan at EAE. Not sure if it's 100% to the DAM version or not but I don't care -...

This is something I came up with while trying to add a bass pot to a Bluesbreaker.

I've heard good things about the Dagger OD so thought I'd try something. I like simplification so rather than using two single op-amp chips I tried using a single dual op-amp. It may (will probably) sound different but that's ok - this was a bit of an experiment. Now I want to try building the...

I had a Music Man amp for a while back in the day. I think it was an RD-12 - something like that. So when I found a schematic for a Music Man preamp I felt I should try it to see if I could remember how it sounded. I built one from what I now realise was a slightly inaccurate schematic. So this...

I recently discovered that a JFET OD I have built on Vero makes a ticking sound when engaged. It's only noticeable when not playing. As soon as I start playing through it I guess it's drowned out by my racket. The other thing I discovered is that as soon as I lift the pedal off the board the...

I've built this before on a PedalPCB board but can't seem to find it anywhere! It's possible that I have lent it to someone and never got it back - I think that happens more than I realise! So I wondered how easy it would be to lay out on Vero. The usual places to look for Vero layouts had some...

I recently listened to the Pedal Movie (because a friend insisted I do) and while a lot of it was obvious, clichéd and self serving there were a few interesting moments. At 6 minutes 23 there is a clip of an old recording of guitar. It's that classic big box guitar played through old amp...

This is why I have pretty much stopped buying from the USA. I used to buy a lot of stuff from the US - clothes, guitars, effects, amp parts - even amps! And until fairly recently I was buying effects PCBs, parts, etc. But I recently ordered a single PCB from PPCB and Robert got it sent by...

I just built a FET City Drive today - it sounds great! But I want to hear other folks experience of this pedal - I can't find much. Mine is quite noisy unless gain is low - Has anyone else experienced this or am I just shit at building PCBs? It also doesn't do low gain - would using 2N7000...

I have finally got around to building the Jump Drive PCB I have had sitting on my desk for ages, and I am so glad I did! It's excellent! I have played and repaired a few old small box '68 50W Plexis and they are one of my favourite amps. The amp I use daily is based on that circuit, built into a...

See this why I love building my own... I really like the BJF designed Baby Blue Overdrive but it sounded a bit thin with my Strat. So Chuck suggested how I could add a bass pot. This circuit is kind of fuzz-meets-overdrive. It's not a particularly twangy or "transparent" OD (Sorry for the TGP...

We've had a fairly mild December this year but for whatever reason today, christmas day, was 42C - that's about 108 in Fahrenheit. We live on the western side of our city, closer to the beach, so it wasn't quite so bad. But we had lunch at our son's place on the other side of the city away from...

I'm building a Sandblaster Fuzz with one of Robert's lovely PCBs. I'm wondering about the transistors - I have some BC182Ls which I believe from my research are pretty much BC182Bs with a different pinout. So I'm wondering whether I should do the twisty leg thing with those or just use 2N3904s...

After the high of seeing the Hives not so long ago we have had a wonderful week of music. Last week we saw the Pixies at Fremantle Prison (well it used to a colonial era prison but now it's a concert venue) and we saw the Church playing their singles this week. I don't know how well known The...

After loving the Diamond Peak and modding it to add a bass pot with Chuck's inestimable help I looked around to find more interesting Skreddy designs - Marc Ahlfs is an incredible designer. And I apologise if I spelled his name wrong! So when I saw my local music shop had an Animals Pedals...
