A while back I got the BBE Two-Timer analog delay, which according to the user manual is based on the Boss DM-2. I'll post some gutshots soon. In the mean time, I opened it up and noted that it's using the Cool Audio Cool Audio V3205D BBD. Also under the hood is the SA571D - apparently a compander - and a CD3102. Not sure what that is - some kind of opamp? Anyway, nice components. Metal film resistors, and those dark red poly film caps. Two 3PDT switches used for bypass and for delay time...

A neighbor lent me this one. It's in rough shape but sounds decent. It's missing the battery cover which also had the name of the pedal listed on it. This is probably a DS-1 though.

IC is a Sony 4558. Transistor are marked either C1818 GR5l or K30A GR5J

This is my first attempt on tracing a pedal. I chose this one (in case you wonder why to trace a pedal for 24,99) because it

a) has a really great swell sound (I am unhappy with my Slow Gear clone and even unhappier with the three failed attempts to get a Paia Gator working properly with my guitar setup: Not to mention the three huge and the one double sided EHX Attack Decay board I spend weeks on and I yet never find the right settings),

b) it is terribly ugly so it needs re-housing in any...

Great sounding box from the old DOD FX range, if anyone's interested I'll do values and the trace side

Hi! I have a bunch of pedals, all of them are true bypass, except for the crybaby that´s hardwired bypass. The problem I have is that I need a buffer in my effects chain, with all the pedals off I notice a loss of high end, istead of buying or building another pedal/buffer, I was wondering if I can use the input buffer of the Crybaby as an always on buffer. Here´s the schematic:

I'll have to add a cap between the end of the buffer and the 68k input resistor, make that cap the output of the...

I was modding mine and the trimpot broke. The guitar signal will go through when it's off and on but there is no effect. Would someone be willing to fix it for fairly cheap. Thanks.

Milin Kamak compressor from 80's (works very well).

Hi
I've got this one on the bench because the owner had used a wrong psu... he toughts that it would run on 18V because of the two 9V batteries, but they are in parallel :lol:
I would swear I've seen a topic about this pedal some time ago, but I couldn't find it anymore. So sorry for the double post.

You'll see their system to access the batteries, it's very difficult to open; also the whole PCB is held only by the two jack sockets ( now you understand why reliability could be a problem...

Sorry for the fuzzy pcb-side shots. It's almost 1am here...

contains some gut-shots from the clone, but i believe the pictures of the degooped original BB on that page comes fromthis forum?
even says BB Preamp on pcb, that is kinda crazy...

A bit noisy, but sounds good.

Hi There

My fantastic twintube has begun to have a weird background noise ONLY on the Rythm channel

Anyone else heard this, can it be the tubes ?

I am thinking about switching the tubes around to see if it then changes to the lead channel.
But its quite a lot of work, with thin wiring.... if any only has any experience with this model, pls let me know

Hi,
I am interested in the filter sweep section of Electro Harmonix Micro Synth.

Could you suggest me some layouts, strip boards or clones project??...

I found this :

I' am reffering to 11ht schematic down the list. I am just interested in attack/sustein control, something like Boss sg1... And the filter section, expecially the resonance enancer.... And I have CA3094...

Any suggestions or other projects??

Thank you in advance for your replies.

I have a Digitech Hardwire SC-2 Valve Distortion. It does the crunchy Marshall voice very well. I have taken 100mb of blurry photos and will disassemble it again tomorrow (I have to find my tripod for this). Prepare for a SMD hellstorm. I cannot see most of the values and ic identifiers. I will get as detailed as possible.

Somebody sent me one of these pedals to try and make it gainier and more aggressive sounding. Schematic is attached! I've never messed with a tube distortion before so any help is appreciated! I'm thinking the key may be to add more gain from the diode clipping rather than tube?

Hi all,

I've got this old Jen Cry Baby and I need schematics fro this layput + 3PDT switch.

Anyone can help me out?

thanks!
