I think there are pcb etch layouts for the Black Forest on diystompboxes, but I'm not aware of any pcbs per se.

One's more high gain than the other.  The 7thHeaven is more rock, while the Black Forest is more metal.  The eqs on both drives are extremely flexible, btw.

Basically, several effects in one box is sorta what I do.  It's not that often that I'll do something with a single footswitch.  It might be a bit less flexible in the long term, but it keeps the pedalboard footprint down (I don't think this is going to make it to the board though).  Have a look at some of my other build reports for more examples (Leviathan and Megatron are fairly extreme examples, Ammocan and Hyperactive Hyperdrive a bit less so).

The 7thHeaven is really asking to be in it's own box with 3 footswitches - on, structure, and boost.

Looks good, I like your pot/vero mounting.  Might try that sometime on a build I have space in....

I leave the figuring out part to the guys at Tagboard....

It minimises the mistakes on the board, but it doesn't stop stupid mistakes like wiring the board ground to the input jack tip....  :o

Gudday all, here's Hellboy.

The red channel is Goosoniqueworx's seventh heaven Bogner red clone, the black channel is Jok3rX's Black Forest Uberschalle clone.  Both are on vero.  I included a buffer to kill any squeal, not that there was, and a charge pump to give a selectable 9/18v.  The boost switch handles both circuits.  In the case of the red channel, the boost is actually on the Structure toggle, and the structure is on the Boost footswitch because it works better as a channel switch that way.

Sounds killer.  That's about it.

My Bat46 replace the germs that go to ground normally.  The back to back LEDs are across pins 1 and 3 of the gain pot, similar to Wampler's Dist+ mods (although he uses different diodes there).

The printout glued to vero thing I learnt back in 86 when I did my first layout for a c-64 controlled robot from the Usborne book "How to make computer controlled robots".  I never finished the robot, but that book says to do that.  I remembered it a year or so ago after not doing it for years, and it's cut the number of failed veros to about 1 in 10, usually because there's a cut under a component that isn't clearly on the layout.

Try sticking a buffered pedal in front of it.  If the squeal goes, put a vero buffer in the pedal before the effect.  This fixes 90% of high gain squeals.

Jubal, I could not believe how good it sounded the first time I put the LEDs in the opamp loop, changing the hard clippers gives it a bit more, and the blend just does it's job.  I was after something nasty but not fizzy, and this really fits the bill.

I really should do a demo.

You definitely want to use a common anode, that way the cathodes can just go to their relevant switch ground points.

My experience with them is that you don't get multiple colours at once if they're all switched on at the same time, you'll get whichever colour has the lowest forward voltage.  I might be wrong though as I normally use them as Red or Green, or Blue (see my Leviathan build where I have one on a rotary switch that switched between a treble booster, an SHO, or the treble booster into the SHO).

Build Reports / Darth Punk - modified Distortion + for bass.

Gudday all.

Here's Darth Punk, a modified Distortion+ with a clean blend as it will be a bass drive for a friend's son.
- Mods:  LED pair in the opamp feedback loop, pair of Bat46 clipping to ground.  The blend is a pcb I got from someone here.

This was going to be a X-fuzz, but it was a bit noisier than I liked, but I'd already drilled and finished the box so I needed a 2 knob drive I could use with a blend.  I'd heard the Dist+ was pretty good with LEDs, but I wasn't impressed with them going to ground so I tried them in the loop.... and holy hell does it sound good with them there.  From there it was a case of trying different diodes to ground.  I tried bat46, 1n4148, 1n270 and the LEDs, and decided to settle on the bat46, although they all sounded pretty good. 1n4148s sucked too much signal out iirc and I couldn't get unity.

It's not often I build something and decide that I'll do another, but I'm going to build one of these for my next bass multi.

I had an issue with the first split/blend board on vero in that it seemed to suck something out of the signal, so I tried a pcb I got on these forums a year or two ago and it worked really well until I did something trimming leads and I didn't get any clean signal in the blend.  I swapped the pcb out for another and it works great.  This is a really cool sounding bass drive.

I did the graphics in photoshop, adding the spikes to Darth's head. 

The guts are a bit messy, but hey, it's half vero and two circuits.

While not repairable, I'm a big fan of the rockboard EBS patchleads.

I suppose you could do 2 of these, using one each for L/R....
