Hi guys, I just finished haringer 2 and I wanted to share few mods I did:
1. Reversed pin 1 and 3 of the speed pot, so faster is toe down
2. Used VTL5C3/2 instead two NSL-32
3. Modded vintage input for megavibe type (omit R2 and change R1 for 100K)
4. Changed speed pot range so I can get faster speeds and slower too (Change R52 to 470R and jumper R54)

Hi guys, it is been a while since I build and post anything.. Here are my 4 recent builds:
1.Aquaboy with modulation and relay switching
2.Diezel vh4 with fet switching
3.Faux Echo with fet switching and..
4.BassDriver DI with original flipflop switching.

Hope you like them..

Build Reports / Echo echo echo (CaveDweller)
August 14, 2016, 04:07:10 PM
Hi guys, here is my latest build. It is MB's CDweller with TH custom effects optotronic bypass and additional jack for Taprecise from Matthias which hopefully will be finished soon. Cave dweller sounds really good considering it's size and part numbers, great design by Brian with jfet instead classic dual opamp.
Here are few pics, hope you like it.

Hi guys, it's been a while since I posted a build report..

I have here another N.Fish which has been populated for long time.. I couldn't find on/on/on switch, so Brian send me one for free and finally it is finished! Yaaaaay! :D This is gift for a good friend of mine who is a bass player. Again I must say BIG thanks to Brian!

Second one is BSIAB2 with contour pot and 18v operation with fet switching, squeezed in a 1590a enclosure. Finish is laser etched faceplate.

Third one is Ego driver I got from Tremster in PIF month of 2014 and it was time box this thing... Thanks mate once again for pcb. Enclosure is etched, painted and brushed..

And fourth one is Micro Vibe, my try on ic based univibe built in 1590a enclosure which is reverse etched and painted. There are two boards inside, one is audio part and other one lfo mostly. I added fet switching, too.

I hope you like them..

Tech Help - Projects Page / Bat 45 substitute
January 22, 2016, 02:47:31 PM
Hi, I need help with BAT 45 diode I couldn't find it anywhere... Do you know where I could find them or what is best substitute for it?

Hi guys, I am having a problem with this build. Tap tempo is not working and tap divison knob, also waveform is missing random function. I don't know how much these chips are sensible, but I did make mistake with orientaton of the socket and I did put chip same way. So did I burn it?  :-\
Open Discussion / Boss DD2 original pcb layout??
April 14, 2015, 04:12:37 PM
Hi, I have broken Boss DD2 for a long time. Problem is that pcb snapped and it almost impossible to repair it. Is there any infos about original layout? Or is there a way to make one? Any help is welcomed :)

Hi fellas, this is Tight Metal-Dragon Armor build I did on my pcb with added 18v operation. It is monster, I never heard pedal with this much brutality. I am super satisfied with it 8) Enclosure is etched and painted with black and than clear coated. I used detour switching for it and I called it 8515, 'cause this year I turned 30..
Here are few pics
Hope you like it

Mods / Vox v848 vocal & Cantrell mod
April 10, 2015, 10:50:57 AM
Hi guys, I did vocal mod, so you can choose 3 different one. First is classic 10n cap, second one I tried 12n for Cantrell voicing but it ended same as 10n so I change it to 15n and last is 22n for those Z.Wylde tones. Also I added A5k pot from pin 1 of wah pot to the GND so you can roll of some of those high freq if you want, just like in J.Cantrell wah. For better range use B5k. It is not sounding exactly as cry baby 'cause Q res is 100k in Clyde and in CB is 33k, also resistor that goes from inductor to GND in Clyde is 82k and in CB 100k.


Hi guys I am thinking about tryin some smd stuff. So what are best matches for:
-PNP,NPN transistors (2n5088,2n3904,2n5087 etc..)
-voltage regulators
..and so on..
Where to buy them?
Build Reports / Pinnacleeeee
April 01, 2015, 02:26:02 PM
Hi guys, this one I finished yesterday. I always wanted to try this pedal and after I build it I must say it sounds great. I wanted to put bakelite alu/red knobs, but musikding didn't have them in the moment, so I ended with what I had.. I redrawn original layout and added trimmers for Q5 and Q6. You must thought of where are those fets.. :D  Well, they are very tiny and they are attached on the bottom layer, so you can use through hole fets or SMT. I did few more tweaks beside trimmers, 'cause this thing had tooooo much gain in the boost mode, so i lowered it..
Here are few pics

P.S. Grounding idea stolen from Cooder :)

Build Reports / Mississippi Drive aka Deadringer II
March 24, 2015, 02:51:03 PM
Hi guys, I didn't see deadringer II build report, so here is one. This pedal was ready few months ago, but I had bad luck with shipping. Four of mine orders from Decembar and January were lost... Anyway, I've etched enclosure and it did stay bit longer in acid then it should be, but it is ok. Only mod I did was A1M gain pot instead A500k and I've put 1M resistor on the switch so I could dial those low gain settings. Also mosfet/diode clipping is changed 'cause during boxing I screw up one IRF510, so instead I have one 2N7000.  Also I used rullywowr's detour switching and it works great. One more thing, I wire boost so it works only when drive is engaged and you cannot use it by it own. Hope you like it and here are few pics..

Hi, I recently build tycobrahe octavia on the tonepad layout and I am having problem with humbucher pickups. When I strum harder on heavier strings it sounds like fast fade in. What could cause this?
