Title: Screwdriver???
Post by: highway jones on March 07, 2011, 01:39:29 AM
I'm surprised this has not come up.  I would like something a little different from a fuzz and OD and this might fit the bill...especially if it does Zeppelin tones as good as they say.

Something like Fuller's Soulbender, or the the "faithful reproduction of the fabled 3 germanium Sola Sound Tone Bender MKII Professional used by Jimmy Page and Jeff Beck" clone (Stone Bender MKII Pro) by ThroBak Electronics?:

That's the pastyface project, a soulbender. The screwdriver is definitely different.

To the OP, the schem is on FSB, it's possible that I might be trying my hand at that one soon.

I have a vero layout from fsb but the offboard wiring isn't ideal as all the pot leads are not located in a single general area.  With 5 or 6 pots that can get messy awfully fast.

Yeah, the screwdriver is  different from tonebenders and appears be an incredible stack mate with other ODs.

Isn't that what the BYOC 2 knob MKII clone is?

Not to draw attention away from here, but guitarpcb.com offers a board for a Tone Bender build.  The schematic is almost exact to the Sola Sound Tone Bender MKII Professional except for a trimmer for bias, 1m resistor at the input and a 1N4001 at the power input.

If done right I would imagine this would be the way to go for those early Page and Beck tones.  A Telecaster might help also.

You could possibley get this together cheaper than the BYOC, plus cutomize to your own tastes.

Yea that kit set me back a good hundred bucks. It sounds awesome but i would have to agree the guitarpcb board would be a much cheaper alternative/more customizable. BYOC just makes it so easy.

I had an actual Screw Driver when I did that vero and the clone I built sounded just like the original when I A/B'd them.  The layout says Screw Driver-ish because Skreddy gets mad if you just call it a Screw Driver.  ::)

I have a layout for this. When I have time to build it up, I'll be happy to post it in the Extra Projects section. No promises on making any boards, but maybe.

Thats awesome. I went through your folder and saved lots of goodies!  ;D ;D
Thanks for having so many wonderful projects available. Between you and Dragonfly's layouts, I believe I have more than enough to keep myself busy for the next year or two!

Nice work ibodog.  You managed to keep the offboard wiring clean.....something that troubles me the most.

I gave up etching for vero a while back.  If anyone etches a board from Brian's layout I will pay $10 for a board for myself.

You don't etch when working with vero board. Really simple after a little practice.

i think he meant he gave up on etching, and is using vero instead.

I'll probably do a run of Screwdriver boards when the layout is up, as well as another run of Formula #5 and possibly WIIO boards.

With a second read, yea you are correct.
Etching would be a great topic to explain in an instructional video. Especially for us not so knowledged about it. I understand the process of doing the physical etch and it doesn't seem to hard, but drilling the boards is what I'm trying to figure out.
That would be great if you offer up some boards! Always trying to keep my eyes open for new projects.

I would also gladly pay someone for etched boards of the Screwdriver and Formula 5.

Consider them available as soon as 'Bean posts the layout.  (No Rush though!)

I would definitely be all over some Screwdriver boards!

Sorry to drag this one back from the depths  ;D  I just built a Lunar Module on the exact same board as my screwdriver. There are two or three parts that are in different places or omitted from one circuit. I am thinking with just two extra part spots you could build either one on the same board (like the AC and Plexi tone or the AC/RC booster). Just thought I would let everyone know. Both sound epic by the way.

I built it twice now (it's also a great way to use up an old stock of leaky russian trannies I have). Make the Presence and Brightness pots trimmers (as per the original) and it cuts down the number of pots nicely. Here's mine sat in with a Lunar Module. Both absolutely brilliant effects. Oh and it's mislabled fuzz should actually say gain for the screwdriver.

Messy inside, there's a lot going on.

Post by: JakeFuzz on May 01, 2011, 05:54:02 AM
Hey juansolo, do you happen to notice sort of a strange crackliness in the note decay of the SD and the LM. I thought it was the trannies but swapping them does nothing for me. It is most noticeable in the screwdriver (b/c the lower gain) but it is present in the LM too. I am thinking it is inherent in the design but it could be the way I made both of them. The best way I can describe it is when the note fades off to being clean, the transition isnt as smooth as my other fuzzes, it very noticeably fizzles off.
