    Tone Bender- diy?

    Hi chaps- I think Im in need of a Tone Bender! & got some pedal build parts like a suitable 2-knob alu box/ switch to house it (unless it needs one of those huAge cool old grey boxes.. assuming not actually neccessary to be this big-?).

    I'd like advice on building a clone.. so can anyone cast any basic light for a novice?

    Thanks, SeaChief

    I don't know Tone Bender from Adam, but it looks like the first thing you have to do is decide which one you want. There are different versions with different circuits - seems mostly ripped off from elsewhere.

    EDIT: CORRECTED LINK!

    They've got PCBs, parts lists, and full instructions Here>http://www.madbeanpedals.com/projects/index.html

    You'll find them about 1/3 of the way down the page under 'classics'

    I don't know if youtube got hacked, but I followed your link and ended up on a Allman Brothers concert. Well, you know how the internet is. Tonebenders, indeed!

    There are many, many iterations of this circuit.

    Pick one & post the schematic.

    Keep in mind that the circuit utilized germanium transistors.

    So, by its very nature, the germanium three-transistor circuit is a finicky design. It seems to sound best with components that are obsolete and difficult to procure. It begs to be tweaked and optimized and fussed over.

    I screwed up- meant to post a link to Wikipedia. Its fixed now.

    The YT link was Flaco Jimenez & Freddy Fender playing Frosty the Snowman. But I can see how you could get them confused with the Allman Brothers.

    I did enjoy Freddy and Flaco. From Freddy, well, I meandered. I did say I ended up on...

    Good link rjb. Tbh I'm needing suggestions firstly on which one to go for. I can't tell a heap of difference between a YT demo of all the mk 1-4 etc, tho mk1 seemed to have more complexity.

    I was wondering if anyone's actually made one?

    I've never built one, but if you can't tell much difference between them the most sensible choice is to build the simplest circuit. Right?

    Well Id say no not neccessarily; if the simplest circuit costs alot more, &/ or is far more difficult to source the parts for, is problematic regarding getting xyz 'just right'.

    Im really needing advice from anyone whose built one. I thought they were a diy'ers ideal clone.. they look made from pretty few parts, & sound great generally speaking afaict/ far better than a generic 'distortion' pedal, which I built a rat clone of & seems about 3x as complex with horrible fiddly 8-leg transistor whanots in, a diy n'mare from my pov to solder in.

    This got me interested, so I ordered a board for a germanium three knob version. 2015 edition. Coincidentally, just last week I ordered an assortment of around 200 germanium transistors along with some mounting sockets. I'll add any other components that I need to an order that I'm putting together already.

    There a lot worse out there to desolder or solder in than a jrc 4558. They're preatty easy peasy, maybe you need more practice, which I got mine from deconstrucing various electronics. i figured if I messed it up oh well. but it was good practice cause with the iron at 408c i can zip them out pretty quick no traces lifted.

    There are a great many things that are called "Tonebender". Some are essentially derived from the basic Fuzz Face circuit, some akin to the Big Muff Pi, and others of a different basic architecture. I'm assuming that your desire to make one is because you heard the name associated with a particular artist or artists whose tone appealed to you. Who might those be? That might point towards the more relevant schematic/circuit, and whatever guidance about parts, construction tips, etc. might be of use.

    Many of those sound bad, biased close / past cut off.
    Sticking AC128s into everything (without tweaking for a suitable operating point) may not be a valid approach.

    Many thanks chaps for the replies & info. The link from rjb has lots of info in the folks' replies twds btm of page in fact, including ref to a couple of diy sites which Id forgotten all about.

    Very useful- appreciated. I'll set about with a plan & report back.

    Until then- merry christmas! Sea Chief.

    I've ordered parts for two different variants of this. One, the schematic that I attached earlier, and also one very close to the Sola Sound MKII original circuit. http://fuzzcentral.ssguitar.com/mkII.phpThe schematic at the top of the page is the one I'll use along with the recommended modifications. I'll build it on perf board. I'm off to San Diego for the Holiday weekend, but when I get home, I'll be testing transistors.

    I have almost everything together for both pedals. The parts that I'm missing, are on the way. There weren't any suitable transistors in the batch that I got, so I ordered a couple of matched sets from a seller on ebay. I found a nice layout that I'll use to build the MKII on perfboard. There's a lot of interesting history related to these. I'm glad Sea Chief got this rolling.

    Thanks Jason. I've been checking out Fuzz Face variants. These look as good as any, and they're cheap enough, so I ordered a PCB, and pair of transistors. You can't have too many fuzz pedals.. can you?

    I've got about 20 of those russian UFO transistors when I have a chance to play I need to build one up.

    Electrosmash has some good pedal breakdowns you should check them out.

    I've got a bunch of Russian, and Asian transistors with similar values. That's why I'm anxious to see how well they work in the electrosmash circuit.

    Thanks Jason. I checked out their site. There's some cool stuff there, but they're pretty centered on their arduino dsp pedals, and their LM386 based mini amps. I thought the name was familiar, and that's why I remember them.

    I don't want to get too far off topic In Sea Chief's thread, but since we're talking about Fuzz Face for the moment.

    Check out the kit I found on ebay. It comes with AC128 germanium transistors. (it's a crapshoot as to whether, or not they're good ones, but that can be fixed) At $22 it's a small gamble, so I ordered one of these too. https://www.ebay.com/itm/DIY-Fuzz-Fa...72.m2749.l2649

    I decided to not use the layout that I linked to in an earlier post, and instead of building it on perf board as I had planned, I decided to make a custom eyelet board. I have some grey forbon, and eyelets on hand, so why not? I did a mock-up of the circuit on my breadboard, including all of the connections so I can lay out the eyelets. It adds a little more DIY , but will make it unique. This is fun stuff.

    Unless you want to mount DIP ICs, eyelet boards rule for "serious prototypes"
    No design (save a basic sketch on the back of an envelope) or etching, far cleaner than perfboard (where replacing parts is a mess), a single hole is actually a node and holds 3 or 4 parts legs so design and drilling is simpler, whatīs not to like?
    I still keep the bench type eyeletter and the 1/8" dies bought in late 60īs "to make boards like Fender did", still in daily use.
    Congratulations on your build.

    Thanks Juan. I realized how awful a cut-up piece of perf board was going to look, and changed plans. I bought my eyelet setting tool back when I first started winding pickups. This is such a simple circuit, It makes it a great candidate for this.
