Here are some gut shots of my TubeWorks Bluetube pedal.

Some notes:

* the two ICs are Ti TL072
* the two FETs are labeled J112
* all the caps are rated for 16v
* the transformer has no discernible identifying marks
* there are no SMD components

Here we go with clickable thumbs:

GUTS:

anyone noticed the similarity's between the RM classic fuzz and the zvex woolly mammoth

i was just looking at the various schems on AG's site and noticed that the RM classic fuzz looked like a starting point for the woolly mammoth.

interesting.

so this is maxon's attempt at a real tube screamer. part of their NINE series. it uses a submini at 30V and has some kind of proprietary power supply. they say that the tube stage runs into the overdrive stage, and there is the option of using it as a booster as well. it's gotta be starved plate, but i suppose 30V is better than 9V. the sound of it ain't half bad either. better than a tube screamer at least.

website-

demo-

i expect Dirk to weigh in on this one, as he is our resident Maxon...

Now there is quite a resounding agreement that the new fuzz faces suck ass... but how different are they from the originals? I am thinking of getting a GGG clone... is it pure original mojo or will it sound like the newer reissues?

can enyone say something about this simple circuit?
is it like the Fuzz Face,or it is different?
schematic?

p.s.

.... Alex Frias is not going to understand this kind of humor..... :applause:
sorry Alex...I know that there is 8 filter array......bla bla bla......but some guts? or schem??? :thumbsup

I was just wondering this.
Would there be any real advantage to swapping the Fet at the input of this for an opamp (I just thought it would probably be easier to source the parts if I drew up a design in DIY layout creator for this)

Hey all!

I found this picture a while ago on the internet by searching on bass overdrive in google. Right now I can't seem to find it anymore.

Can anybody tell me something about it? I can't find if it is an idea, an already exsisting pedal or something completely different. The 6E5 tube is awesome (magic Eye)......... although I don't know it's function there then to determine the overdrive.

I'm asking as I am designing a new bass amp for myself (ultra lin 6550 amp) and I know it'll lack...

Please don't resist the urge to place comments in case you do (or don't) :scratch: like.

The FL99 that is, another one from the Neo-classics:

Which one is that? That's what we're going to generate some traffic to Bart's place for:

That one.
So there's a schematic? Yes there is now. Kudo's for those who dare to think about cloning this one. That BBD is going to be close to impossible to find. First time I saw one anyways.

yeah, schematic time:
Ibanez FL99 Classic Flange Schematic

Maybe somebody can explain me, why people spend more than $300,-- for a solder-jockey clone/derivate, when they can get the original reissue for only $99,-- ?:

Hey cats,

I have a morley dual bass wah, if you go to morleys site, they post the origional bass wah they made. This is practically the same, with just an added switch for a different wah sound...ooh fancy. :|

What Im looking for is a mod for a lot more mid honk, it seems like its got too much midrange cut, and this is fine in a bass amp or preamp, for funk and stuff, but I want my wah to..well..just get uglay.

Any ideas what to change or look for and what values I could have some fun with....

Currently in my hands but going further... What little info I have is this:

These settings were used for testing (12db boost/cut):

Test file:

What you hear in the test file:

00.00 - 00.06, Bypass signal

Heavy Fuzz Test:

00.06 - 00.13, EQ on, neutral position
00.13 - 00.50, 12dB bass boost
00.50 - 01.05, 12dB bass cut
01.05 - 01.48, 12dB mid boost
01.48 - 02.12, 12dB mid cut
02.12 - 02.35, 12dB treble boost
02.35 - 03.10, 12dB treble cut...

That's the schemmo. Nothing new. That one was available so far.
Then why this topic?
Because while spending an afternoon datachrunching over an Ibanez Effects timeline it occured to me that the SH7 has been, at least catalogwise, never available in the US.... And that smells like a result of patent infringement.

Anyone with a clear explanation or proof of temporary stupidity at my side?

Enjoy ;)

I was wondering if anyone had anything on this particular pedal?

Thanks for any info. :D

Guys,
I'm new here, I certainly got great interest when I saw Bajaman's active version of Harmonic Converger :D
Wished that some member also may have show significant interest on the PASSIVE version so as to give Bajaman enthusiast and/to create a DIY project for us to have.

Just to link you to the NEW Harmonic Converger website for an update if ever and so much thanks

Kampai,
Roger

Its not very helpful for values, but here it is...

Here are some guts from a Proco Turbo Rat:

ATTENTION ! This Turbo Rat has been modified:
.... the modifications include Fulltone 3pdt switch, silver solder connections, socketed opamp with your choice of 2 LM308 opamps which are included in this auction.

The opamps are shown here:

Since they are made from the same Si-wafer the only audible difference will be: the case. :lol:

If you want to buy this Mojo-Rat you can get it for $100,-- only... here:

And, while drawing the thing I wondered about the fact that this was the last Parametric EQ pedal that Ibanez issued. No more in the 10, 5 and 7 series :roll:

nevertheless,
The Ibanez PQL Parametric EQ's schematic now ready for download:

Hi there.
some guts from here:

I just acquired one of these little drum machines. It's a little hacked up under the hood. Anyone have schem? I struck out with google.
Thanks,
Rob

So I have this PSK pedal in that needs some repairing....... and while opening it up I had this sensation of I have seen this before..........

5 minutes before that I just finished repairing a Boss BF-2B

Spot on copy of the Boss BF-2; except for the manual knob. In the Boss pedal the depth knob goes into the manual knob, in the PSK the depth pot is grounded on that side.

Pics:

Hello people!!!

someone have EH Steel Leather original for pics inside? or layout

thank you!!!!

I tried searching first, but couldn't find any info on the pedal. So, here's my question... Has anybody ever added a volume pot to the M-109? I love the EQ, but sometimes wish I could use it without getting a volume/gain boost. Anybody care to shed some light on how to go about doing this? What type of pot would be best, and should it go before the circuit or after the circuit? Please tell me it can be done without touching those damn SMDs :|

I can provide pics if needed.
