This is another layout by David over at effectslayouts of the Mad Professor Deep Blue Delay work-a-like. This is one of my favorite “simple” delays out there. Its got 2 basic controls and a mix knob. This circuit does a great job working with the PT2399 delay IC and keeps the noise down to a minimum. I built this for a multi build I am making and really happy with how it came out.
This is a proto from David over at effectslayouts blog. I was needing a Rat for a multi build I am working on and it was perfect timing for him to ask me to build it. Whats cool about this Rat layout is that it supports 4 different Rats (Rat, Rat2, Turbo Rat & You Dirty Rat). I went with the classic original Rat for this build.
Here is 2 of the Rats etched and ready to go.
I could not decide on what clipping I wanted to use so I went with all of them. I used a mini 2p4t switch and just used one half of it for the clipping selector. This switches between pairs of 1N914, 1N4148, 3mm Red LEDs & 1N34a in a symmetrical configuration.
I went with a LM308AM IC in a cool metal can… why? cause I had them on hand. In this picture you can see the little copper halo I made for the clipping switch. It looks like a mess but it works great. I still need to trim the legs on the IC before it’s mounted in an enclosure.
I always seem to forget this.. time to note it so I can find it easily when I forget again.
Switchcraft Panel Mount holes are 7/8″ round.
Now that I wrote it down I should always remember… right?
Tonight I was able to verify this Catalinbread Katzenkonig work alike layout by Stroyboardist.
Howard from Catalinbread said this on Madbean Forums about the transistors:
they’re not 2222s… I’m using something in the 300-400 range though.
So for something in the 300-400 Hfe range I went with 2N3904’s that were matched around 380 Hfe for all 4 transistors.
This thing sounds great. Time to get it boxed up.
Tonight I finished up a build that has been been floating around on my bench for months. I had a RAH clone I built last year. I really loved the 3 band EQ and it has a very natural sounding tube breakup sound. I really just wanted a little more umph for it, something to make it breakup more and become more of a medium gain OD. I built a Rullywow Serpent Boost (Naga Viper work alike) to get a nice dirty boost before the RAH and the RAH Deluxe was born. This thing really came alive with the boot in front of it.
I did a reverse etch of some artwork I mashed together of the Zeppelin and the Royal Albert Hall.
Gut shot: Not so clean but I had to do some ninja work to get the top mounted jacks in there. Works for me.
This is a Aion Flare which is a modded Fuzz Factory. This pedal is one of the most loved/hated fuzz pedals from great smooth sounding fuzz to very velcro/gated sounding fuzz to straight up broken/non-working fuzz. I don’t know why I even bothered to label the knobs since they really don’t matter a whole lot. Its more of a “tweak and play” kind of fuzz. I usually find settings I like while knob twiddling and then take a picture with my phone to remind me of the settings.
I used a couple AC 128 transistors in this build but I am still swapping around until I find the best ones.
I did a reverse etch, which is hard to capture on camera but I think it turned out great.

Just finished up a awesome Boss CE-2 work-a-like from Brian over at Madbean Pedals. This is a very lush sounding chorus pedal. I decided to go with the MN3007 BBD and it sounds great.
I did a reverse etch with some artwork I found I Google Images and edited it a bit to fit the pedal.
