Hey folks!

Here's a seperate topic about the Auto-panner I posted about earlier in my introduction thread. I recall that jimilee asked for an audio demo so I did a quick little recording using two amplifiers in a stereo setup. In the audio demo I'm using an expression pedal to modify the panning speed of the effect (this is also switchable).

On the left I'm using some sort of Marshall clone from the 80's (it was given to me by an old friend a couple of years back, runs on three AX7's and two EL34's with a Baxandall tonestack... or at least I think so :o ) and on the right sits a 60w Fender Deville.
I'm also using a MiM Fender Strat with DiMarzio hotrails in the neck and DiMarzio 'buckers in the bridge. The bridge 'buckers are coil-tappable.

Other effects I used were a GrindCustomsFX Tenebrion reverb on the Marshall clone, a touch of spring reverb on the DeVille and later on an MXR Phase-100 clone and a DOD FX65 chorus.

Most of the 'modulation' came from the Auto-panner though. Guess it 'sounds' like modulation due to the ears being tricked there's a phase shift of some sorts going on, yet all that happens is the fluctuation of volume from left to right. I don't know a whole lot about this subject, so please forgive me if I'm wrong (I'd love to learn what causes this funny effect though!).
Oh, also, I could finetune the effect to be completely off/on on the respective left/right channels, but I figured this sounded best. Sounds a little like some sort of Leslie, I really dig it ;D

Enough text, on the audio demo! I recommend listening to it with some good headphones to emphasize the panning effect.

Here's a photo of the Strat I mentioned:

Hello people and pedalbuilders of Madbean!

I've been a long time lurker of this forum, always checking out other people's builds to learn from them and apply them to my own pedalbuilding experience. So I figured it's about time I posted some stuff and shared my experience as well.
I'm 24 years old, I live in the Netherlands and have been building my own effects since approx. November 2012.
I've always been kinda sucky at introducing myself at forums so I'll move straight on to the pedals.
Note that most of these are quite recent, as most of my early pedals looked quite iffy on both the outside and the inside - although most of them did work, surprisingly without much tone suckage.

Anywho, on to the pedals!


First up is a Timmy clone on veroboard. This one was made in mid 2013 I believe, my wiring wasn't as tidy as it should have been back then. Sounds killer though. I put some heavier caps in there as well so I could apply an 18v supply. I also put in a DPDT switch to accomodate more clipping options. All diodes are 1N4148.
The smiley is derived from Newground's "angryfaic" smiley and the LED's glow bright red when the pedal is engaged.






Next up is a stereo auto-panner on a PCB from musicfromouterspace.com.
Built this one last February I believe. Looks a little battered due to the paint not being super high quality (probably also because I sprayed only about two layers and a layer of clearcoat).
This one was a little tricky, as it needed a bipolar (+12v/-12v) power supply which I don't have. I decided to use a voltage inverter to produce -9v for the necessary negative supply rail. I also incorporated an AMZ FET signalsplitter/buffer circuit in order to maintain stereo output in bypass. The AMZ buffer gets its power from an 18v charge pump.
I also added an expression pedal jack, so the panning speed can be adjusted by an expression pedal. When used properly it produces some nice lesley-esque swirling tones.







This one's a Colorsound Overdriver clone on a madbean PCB. Sounds fantastic. I've got to say I'm quite satisfied with how tidy it turned out.
I put some electrical tape on the tranny's (2N3440 @ Q1 & Q3, 2N2219A @ Q2) to prevent them from shorting via the enclosure. Think I built this one around last April.






Completed this one yesterday. It's an MXR Phase-100 clone from GGG. I decided to make the center-frequency 25k pot an external control for more variations in sound. Also decided to use two DPDT switches with LED indicators instead of a multi-pole rotary switch because I didn't have one.
Could've wired it a little tidier now that I look at it, but it works and it's noise-free so I'm satisfied :)






And last but not least, a big muff clone on a madbean PCB. This was one of my first builds. Works fine but looks horrendous on the inside - hence I'm not posting any photos of the innards (such spaghetti). The two switches on the side of the enclosure switch the clipping diodes in the feedback loops of Q2 & Q3 - either a pair of 1N914's or a pair of 1N60's.





And finally a complementary photo of all pedals engaged.




Thanks for reading, please let me know what you guys think! Some good criticism will be well appreciated :)
