Build Reports / Engineerís Thumb
« on: December 13, 2020, 08:31:02 PM »
I built one of these years ago on the awesome PCB offered over at JMK PCBs and regrettably sold it to fund another project.  Mr Bean PIFíd me a 5-knob proto iteration, which I modded it back to stock specs in order to use the toner transfer I already had printed up and avoid placing an order for more pots.  Iím a less as more kind of guy anyways so all the knobs wouldíve been overwhelming for me anyhow!  Thanks again Brian for the awesome PIF and to Leevibe for the knobs, which look pretty great IMO.  And thanks to you guys for taking the time to look.

Build Reports / Deluxe Dirtbag
« on: November 30, 2020, 10:36:11 AM »
I pick this one up shortly before the total recall was released. It ended up collecting in the dust in a drawer for a few years but I finally got around to building it. I had a lot of trouble getting this one to work, and probably shouldíve tested it before boxing it. Ha ha. In the end I got it all figured out. Iím too burnt out to calibrate it so Iíll probably wait until after Christmas just in case Santa brings me a looper pedal.  ;D

Tech Help - Projects Page / [Solved] Need help Dirtbag Deluxe
« on: October 11, 2020, 09:59:48 PM »
Iím working on a Dirtbag Dx and wanted to use 1uf poly caps in place of electros where possible.  I compared the Dirtbag to the Total Recall which has three 1uf poly caps.  Only problem is that one of these caps is listed as a 4.7uf on the Dirtbag schematic (See pic below for comparison of schematics).  Is it okay to use a 1uf poly in this spot or is the 4.7uf required for the Dirtbag version?

Build Reports / Hamlet Delay (perf board is for masochists)
« on: July 23, 2020, 07:14:18 PM »
John Patton is a masochist.  There, I said it!  ;D Seriously though, building on pad per hole perf board is one of the most challenging things Iíve done pedal-wise.  I was absolutely shocked that it actually worked!  Kudos to John for this great project! Still one of my favorite Delays.

Build Reports / Barrel oí Pork
« on: July 08, 2020, 07:31:43 PM »
I just finished up a Porkbarrel for a buddy of mine and thought Iíd share.  I was planning on backfilling the reverse etch with black spray paint but I ended up liking the etch enough to leave it alone. I also left the mix control off but Iím definitely interested to try that sometime down the road.  Unfortunately, my stash if MN3007s just ran dry!

Build Reports / Porkbarrel
« on: January 19, 2020, 09:07:16 PM »
I was hoping to have this one done for the BOTY but I ran out of time waiting on a supplies order.  Hopefully this is the first on many build reports in 2020. Happy new year everyone!

Open Discussion / NGD: I took a gamble and it paid off
« on: April 15, 2018, 10:18:32 AM »
So I pulled the trigger on a 2018 Les Paul Classic body and neck from Stratosphere (no affiliation) after falling in love with the guitar at Guitar Center last month.  I was pretty nervous about potential issues with the guitar but it came as described in mint condition with no issues! The guitar retails at $2,299.00 but I was able to buy all the parts and put it together for $1400.  All the hardware, etc. came off the guitar or another 2018 LP Classic except for the Grover tuners (I'm not a fan of the kidney style tuners that come on the guitar) so it is pretty much stock. I also replaced the truss rod cover with a blank cover for a more I vintage look. I need to get it set up but it plays great and the neck is perfect.  The P90s sound really nice for stock pups.  I was initially going to use a set of P90s that Timbo wound for me but I couldnt find covers that fit the routing AND has the correct pole spacing.  So here are the pics:

Tech Help - Projects Page / Rust bucket Voltages way off
« on: September 09, 2017, 10:58:05 AM »
So I built the rust bucket a long time ago and based on the notes in the build doc I initially thought it was working as expected. However, after listening to Demos from other members builds I started to think something might be off.  I finally pulled it out the other day and measured voltages and found a bunch of inconsistencies with respect to those included in the build doc.  In particular,  ICs 7 through 10 are off.  Strangely, the voltages on pins 1 and 2 of IC7 are reversed??.  The emitter of Q2 is also way off from the listed voltage.  Voltages are included below. Any help debugging would be greatly appreciated.

Build Reports / Demo Tape Fuzz
« on: August 15, 2017, 10:23:16 PM »
Recently I've been devoting most my personal time to building an amplifier so this is the first pedal I've finished for myself in a while.  It's a Demo Tape Fuzz based on Brian's schematic in the etchers paradise section and it sounds awesome.  Designing for the Bare Box took a bit of extra effort but the build went surprisingly well.  I used Cricut inkjet vinyl sticker paper for the graphic and envirotex for the finish.  The jumpers are a borrowed idea from Leevibe's Phase 45 build (thanks Lee).  The graphic is based off a BASF poster I found on the web, which for copyright reasons I'm guessing used "BASE" in the logo.  Somehow I didn't catch it (face palm) so I guess I unintentionally avoided copyright infringement.  ;D

If anyone for some reason is interested in building one of these, i have the leftover PCBs for sale here:

Build Reports / Madbean Smoothie redo
« on: February 19, 2017, 04:16:41 PM »
So this one marks my return to the world of decals.  I pretty much ditched them a few years back due to inconsistent results but after seeing how great envirotex looked over some of my recent etches I decided to give it another go. This is actually a do over for my dad. It's a Madbean smoothie that looked horrid inside and out.  The krylon clear coat never cured and it was embarrassing to look at to say the least. The wiring was pretty bad as well and there were a couple partially melted caps, which I replaced.  IIRC, I actually removed all the components and started fresh but that was a while back. Other than the poor drilling, which I couldn't do a thing about , I'm really happy with the result. The decal is an adhesive vinyl sticker paper made for ink jet printers that I found at JoAnn's Fabrics.  It worked well for the small enclosure but I'm having issues with bubbles on a larger enclosure I'm currently working on so I'm thinking white waterside may he the better option. In order to make the envirotex work with the 9mm Alpha pot I used a plastic drink stirrer to tease a thin layer out to the edges, which left plenty of thread to tighten down the nut. Sorry so long winded here.  Hope you like it!

Build Reports / Cascadia multi-fx unit
« on: February 04, 2017, 11:13:43 PM »
I finally got this one boxed up and threw it on the pedaltrain nano+ I got for Christmas this year!  This one has been in the works for quite some time.  The effects are op amp buffer (always on) > MXR Micro Amp > Long Block Overdrive (designed by Leevibe) > 2010 aquaboy.  I added a daughter board to the Long Block OD so I could implement the add on's that are available on Lee's  Big Block OD.  There are 6 clipping options, a warm/mid/fat switch and a smooth bite switch. So far I am digging the mosfet clippers with mid and smooth caps in the circuit but I need to put more time into it deciding on what to stick with. I had some issues with noise from the compander so I switched out C7 (C10 equivalent on the 2016 aquaboy) for a 470n as suggested by Brian in this thread:  http://www.madbeanpedals.com/forum/index.php?topic=24783.0
It worked like a charm. Thanks Brian! I also decided to run the Aquaboy at 15v via Road Rage so I had to up the value of R31 (R30 equivalent) to get the self oscillation calibrated.  Now it sounds great and I have to say, the Xvive chips sound REALLY nice IMO.  Arguably quieter/better sounding that the vintage MN3005s I've used, but maybe my ears are playing tricks on me.

General Questions / Wet Sanding / polishng envirotex?
« on: February 04, 2017, 10:58:56 AM »
I finished a pedal with Envirotex the other day and there are a few bumps in the surface that I'd like sand and buff out. I'm pretty sure it can be done, but I don't know what to do exactly. Has anyone tried this?

Build Reports / Freakout!
« on: August 29, 2016, 01:25:02 AM »
Here is a Freakout finished a while back.  Definitely a cool circuit and a nice addition to the collection. Initially I boxed it with a bare etch and after  a few weeks I took it apart and decided to paint, wet sand and give it a grungy look by sanding the enclosure at an angle with a 100 grit sand paper.  I boxed it back up and was happy with it until I started working with envirotex. Long story short, the guts came out again!

Build Reports / Small Clone Chorus (2016 Penneyroyal)
« on: August 03, 2016, 10:03:34 PM »
Here is my latest version of the EHX Small Clone.  This version is a bit narrower than the last which should make boxing it in a 1590b a bit easier.  I tried to adhere to better design practices and overall in happy with the outcome. The last layout was honestly a bit of a mess. ::) Not much different circuit-wise other than replacing the 1uF caps and polarity protection diode but it sounds really nice. Thanks for looking!

Build Reports / MB Retrograde (Octavia)
« on: July 26, 2016, 09:56:12 AM »
My pops was interested in the tycobrahe octavia circuit so I decided to surprise him and build one for his birthday. Once I started reading up on the circuit I had to have one for myself so I ended up building two of them. I don't regret the decision! This is one mean octave fuzz!

It took many attempts to get the red/blue splatter paint just right.  I must have started over five times!  I initially wanted a red white and blue splatter theme but the white didn't look as good as I hoped.  I even tried white knobs instead of white splatter but it just didn't translate for some reason.
