More different than I thought at first...

Here are pictures of my Yamaha CO-10MII

So I got this little unit (I know there is already a thread on the wah-wah switch+, this is the '92 version without the +)

I expected a optical wah pedal like all the other George Dennis pedals I've seen and worked on.......

caline cp-26 snake bite reverb

i don't really know what this one is about as it seems to be dsp or something, but it sounds great and cost no money (£30) so i got it. sounds amazing with my alesis sr16. really places the drums in a time and a space.

as it's a chip am guessing that most of the business goes on in the program rather than the components, it looks a nightmare to trace. but if it is a clone of something known and out there then maybe the group of chips involved should tell their...

I sprayed some clearcoat on a few boxes in the morning and didn't have that much to do while the laquer was drying up. I decided to take this one up. The schematic that has been floating around for years always makes my eyes bleed whenever i try to look at it. So i thought it would be time to redraw this. I'm relatively new to tracing boards and producing schematics, so there is a chance of errors. I did refer to that previous schematic and couple of Dirk's Soundtank series schematics (huge...

BOSS BE-5M
Programmable multiple effects

Effects in this one are not the same as in the BOSS BE-5, at least the compressor circuits are different.
BE-5M use THAT 2159 VCA for the compressor, unlike BE-5.

IC's in BE-5:
chorus: MN3207 and MN3102, TL022
delay: MN51010RBA, uPC1571 compander
opamps: M5218, M5223, BA728

Hi,

Bought a dead one for cheap to have some parts to refresh some working ones. The pedal is some Dynacomp clone, and I've got one working nicely over here, so I left it apart.

Finally decided to have a closer look at it and traced it ( thanks to snmavronis for his schem :wink: ).

It's quickly drafted, but it's enough for debugging purpose. I've numbered the extra components in the signal path, and left the flip-flop part un-numbered...

I have one of those puppies in house Quick google scanning shows no schematic. Do we need one? I could try to do it. This one is not working, my friend left it to fix it by me (haha!).

So, everyone knows the MXR Blue Box, legendary octave fuzz. It fuzzes the signal, than blends it with a 2 octave down signal.

Two controls, simple: Blend, and volume.

But I thought, what if we took that blend control, and put it to the front of the pedal, put both sides through independent gain circuits, and then putting one directly through the octave effect.
Here's a Blue Box schematic.

What does everyone think?

I have a Ibanez PH7 phaser from the tonelock series and it sounds ok but not great. I wonder why? Can it be improved?

From:

Schematic:

I checked the schematics and see that the PH7 is a FET phaser. Should be able to sound good, right? Perhaps the FETs should be swapped with matched ones?
FET type is a 2SK246 N-channel JFET:

It seems to behave like a nice variable resistor looking at the Id-Vds curve.
Would some matched 2N5952 be better, like in the MXR Phase 90 tonepad project? I...

I do not know whether this is the right place but still kind of stompboxes.

Hi everyone,

on my never ending quest for headroom, I wondered if the CP-10 could be run at 18V? Apart from all the usual caps, the Rohm BA6110 data sheet states the maximum supply voltage as 34V. Any ideas?

nuX is a little known chinese company, a division of Cherub. They produce some fantastic pedals (I've tried the flanger and I bought the chorus) they are made with good quality components and metal casings.

This chorus is quite versatile, very warm sounding! Can go anywhere from subtle retro to quick warble.

It looks unusual but unique!

I'm not sure if this is a clone of anything..I'm not too familiar with modulation effects circuitry. Anyhow I have attached the factory schematic for...

clip of a BOD400 !

Guys.

Here it is the schematic of this wonderfull compressor
Traced it myself

Regards

I have a EBS octabass that has a kind of heartbeat sound in the background all the time, it changes a bit with the range switch

Anyone else has seen/heard this ??
what to do ?

Hi everyone...

Brian Wampler offered the idea of turning the last two sliders of ab Boss GE-7 into a presence control (Twin Mod).
I wondered how this applies to an Ibanez GEQ10 (schematic attached)...
Any body got an idea and some enlightening explanation on how the gyrator-circuit is changed?

Cheers, Florian

Hi guys,

can anyone explain the circuit of the distortion in the Boss ME-5? I´d like to mod it, but I´d like to know what does what first instead of soldering by some other guys´ numbers... Which doesn´t mean that I´d not wildly applaude any suggestions...

Cheers!

My first pedal was a Morley Power Wah Fuzz - anyone done anything with the Fuzz circuit or know what its like ???

So, I got this unit in for a pedalboard cleanup and rewire and just wanted to see what's under the hood.......

Bright pink pedal, enclosure just too big for the underside (little gaps on the side).......

From the website:
With 350 milliseconds of variable Delay Time BBD IC the AD-350 can produce a wide variety of time-delay effects, from Rock-A-Billy slap back echo to erratic, runaway delays.

I was guessing some analog delay; but it's not, it is again another PT2399 delay;...
