Make-It: Ibanez Tube Screamer T-808/TS-9 Clone! (Phase 2)

I managed to find a bit of time to work on this little monster! So, I got the board ‘planned’… or almost all planned.

Previously, I had decided on the external location of the parts but had no clue about the board by itself. Now, I got all the little drawing done on the protoboard. This is going to be a sick-crowded board ! About 40-50 parts on a 3″ x 2″ board, as minimal jumper as possible. So here it is… ( Each black round around a hole mean that there is something that goes there… either a part lead, either a jumper lead or a wire).

UPDATE: For those out there who would have wanted to have a better view of the designed board, here’s the GIF version of the connections.

(End of update)

Sadly, I can’t finish it since I noticed that I’m missing some parts for it (and I don’t want to do a botched job while using wrong parts). But at least, here’s a few ‘progress’ pictures of how crowded the board will be.  (1st pic is about 1/2 of the parts, 2nd pic is about 3/4 of the parts; none have jumpers or wires yet nor potentiometers hooked).

Make-It: Ibanez Tube Screamer T-808/T-9 Clone! (Phase 1)

So I have found a schematic to replicate a Tube Screamer T-808 or T-9 made by Ibanez. After hearing the sound, I knew I wanted one (especially since I managed to borrow a small guitar amplifier from my father!)

the T-9 Vs the T-808 are fairly similar (the T-808 have a few more parts at the ‘end’ of the circuit) so my initial prototype will be to replicate a T-9 pedal. I already went to the Electronic Store to get the missing parts so, I’m ready to start.  I also have already planned the hardware disposition in the box (better than for the FuzzFace :P)

As far as it is advanced, I have some parts of the board/schematic planned out but it’s going to e a pretty crowded board when I’ll be done with it (tons of parts, especially if I do the T-808 version) on a small-ish board 😛  I’ll keep you guys updated!

Fix-It: Ross Distortion Guitar Pedal (Phase 1 – Final)

Ok, so I got this guitar pedal that was said to be not working…  a somewhat oldie but in fairly good shape “Ross” brand Distortion Pedal for guitars.

Indeed, as the person who handed it to me said… if it’s plugged, no sound come from it… only a ‘hummmm’ …  So I sliced it open (read: unscrew the back panel), checked out the circuit… everything and torn it out in piece…  nothing… No visual issue, nothing looking wrong, chip is properly inserted in the socket…  everything looks fine…

So… I had a genius idea…   … …  could it be the battery ?  … I checked out the 9v … and it’s dead dead dead…   -_-   I replaced it with a new one … and Voila ! Magic happen again…

My advice for today… and to myself…   Check the dang battery FIRST ! 🙂

(( on the bright side, I might take a quick look at how I could recreate a Distortion pedal like that 😛 the IC is a simple Low-Noise Dual Op-Amp 🙂 and all the caps/resistances are not a big deal 😛 soooo… I might make my own clone of it soon ! ))

Make It: “Fuzz Face” Clone Guitar Pedal

I recently got dragged into Guitar Pedals Schematics by a friend and It kinda gave me the ‘wants’ to make one for my father… so here’s the build log!

I started to research schems for the Fuzz Face Jimmy Hendrix used (there was quite a few in fact) and after a hint from my father (Arbiter), I knew what to look for. I have found some REALLY awesome info from the guys at Fuzz Central (Link) on the original Schems for the Fuzz Face with different version available. I decided to try my luck with the ‘Silicon Era’-type (using 2x “BC109” transistors in my case). I really went with the original design (that I tweaked a tiny bit). Oh and … FYI… this little monster did cost me less than 20$ to build ! and I had almost no parts (except resistances and caps).

Started by gathering the parts and making my proto board:

as you can see, I went for a sweet old-style Pot button 😛 Oh and, I ‘though’ I would do the proto like that… but we all know that things ‘change’ here and there once in a while 😛

Once all the electronic was soldered, I started to attack the casing:

On a side note, If I would redo the case, I’d put both In and Out jacks on the same side to save a bit of space inside and I would redo the wiring to have less. Right now, everything goes to the board even if it’s just 2 wires connected together… so It adds up a bit… and quite honestly, it adds up FAST !

So here’s the semi final of the box:

After a bit of looking at it, I decided to hack in my circuit to add a ‘Power On’ LED… which wasn’t too hard afterall… and I put the labels on what-is-what 🙂

Enjoy !

Afterthoughts:

-Use both jacks on the same side to free up some space.
-Add the bypass switch (couldn’t do it in this one due to space issue).
-Wire the cables directly to where they should go instead to ‘All-To-Board’ method.
-Get Countersinks screw for the board and some better holding system.
-Get some audio wires/jacks to test that kind of prototype… because Alligator clamps can be tricky to work with…
