Build Reports / KOT Clone of Tones
« on: March 18, 2020, 07:34:47 AM »
KOT Clone with some 8ball inspired mods: 47n input caps for a lil more bass, 250k gain pots, 100pf caps in the loop of the IC. It sounds quite glorious.

Tech Help - Projects Page / Compressor Hell
« on: March 14, 2020, 09:36:39 AM »
I think Iíve been cursed by the ghost of vactrols past, or something, because I canít build an optical compressor that actually works.

I finished building and boxing the Convex and Oceanid projects from AION FX over the past couple of days, and have had a persistent problem: terrible hissing and/or distortion when the comps are on.

Here are some pictures of the board side of the compressors:

And here are some audio clips of the behavior.

Recorded with low output (Lambertone Crema) humbuckers. The same behavior occurs when I use my Tele with single coils.

I am stumped.

IC voltages for the convex are


G: 1.85
S: 4.47
D: 8.98


B: 0
E: 0

E: 7.48
B: 3.93
C: 0

C: 0
B: 8.25
E: 9.1


E: ???? Draining slowly from 1v to 0???
B: 0
C: 9.09


Ic1& IC2 - essentially the same a few milivolts lower on IC2

1: 4.89
5: 2.44


1: .01
2: ..01
3: .03
4: 0
5: 0
6: .05
7: .025
8: 8.84


1: .14
2: .14
3: .04
4: 0
5: .08
6: .14
7: .72
8: 8.85

Q1: C-B- E


Q2 : CBE

7.98 - .69 - .10

I hope thereís some clue in these numbers. Iím going nuts!

General Questions / Smallbear Macron 5ctlXxx pin out?
« on: March 07, 2020, 03:09:25 PM »
I have been pulling my hair out trying to figure out the pin out for the Smallbear/macron vactrols. I have a pair of 5ct3 work alikes for a compressor and I canít for the life of me figure out which leg of the LED side is the anode and which is the cathode.

The dot is on the opposite side of the letter (a ďcĒ in this case) and is on the same side as the short leg. Normally I would just stick the long leg in the square PD and be done with it, but these things are screwy.

And I am also too breadboard incompetent to put a LED in series to figure it out that way.

Send help. Please!

Build Reports / Supreme Klone II
« on: October 09, 2018, 09:41:18 AM »
Sunking II. Could only fit 2 of the 3 switches, but kinda wish I had just left all the mods off. d9e and LED diodes.

It sounds great. You can also see the computer amp-overlord in the picture.

Open Discussion / Put Stereo Effects in Paralell - RJM Line Mixer workalike
« on: February 12, 2018, 11:25:44 AM »
Is there a project out there that can do this? I am no routing genius, but would like to put my SA Nemesis/Ventris in paralell in the loop of my Kemper. In an ideal world it would take the mono send from the amp and send it to the two stereo effects, then put those fx in paralell at a stereo output.

I know it's not very DIY but it's what I need now! Any ideas?

Open Discussion / Digital Disease - Kemper!
« on: November 19, 2017, 07:46:56 PM »
So about 6 months ago I bought a Kemper profiling amp. I was looking for a silent stage solution, and didnít want a Helix or axe fx.

Long story short, this thing freaking rules. The onboard drives are meh at best but the amp sounds are amazingly sweet, and the wet effects are good too. Iím still running an unnecessarily huge pedalboard, but canít imagine going back to an analog amp for my current playing situation, which is either at home with the chilluns sleeping or at church with an otherwise silent stage.

Has anyone here gone over, in whole or in part, to a digital solution?

Since it's April, right?

Not that I have any time to build anything.... but still :)

Open Discussion / Any reason NOT to buy an h9
« on: December 22, 2016, 11:16:28 AM »
Thinking of buying an eventide h9 (max) and moving to that system for all of my delays, reverbs, and modulation needs.

Anyone go that route and regret it? Any Strymon apologists want to talk me into the holiest of trinity's?

Open Discussion / Ernie Ball Volume Topper
« on: December 15, 2016, 07:16:36 AM »
So I wanna etch a topper for an Ernie ball volume pedal - what would you guys use for a faceplate? And, more importantly, where would you get it?  I'd prefer to use aluminum, not fr4.

Open Discussion / Ceramic v. Film - Small Value Capacitors
« on: October 31, 2016, 12:13:32 PM »
I am trying to come back from the pedalbuilding dead, and get some new builds going!

One thing I have been thinking about is the (relative) inconsistency of small value ceramic capacitors. I was poking around on mouser today, and found that WIMA has small value film caps that should work in most builds. Not cheap, but 5% tolerance instead of 25%.

Worth it? Has anyone ever actually tested the effect of capacitors on low voltage circuits? Will my crystal lattices be shinier with all fancy caps?

Open Discussion / New Hammond Enclosure / VFE Pedals Kickstarter
« on: September 08, 2016, 07:40:09 AM »
I recently saw this kickstarter:

Pedals look cool, very functional. Most interesting, though, is the new hammond enclosure size, which has the same footprint as a 1590b, but is taller for TOP MOUNTED JACKS.

That's right, I said TOP MOUNTED JACKS


Not that anyone round these parts like jacks on the top.

One's for sale at a local yard sale, for $125. Buy it or pass?

Open Discussion / Guitar neck question
« on: April 29, 2016, 06:20:36 AM »
I have a partscaster that I assembled like a ham fisted hack. I managed to split the neck at the heel, but the crack doesn't go all the way through.

It really needs a new nut and setup. I'm thinking of just bringing it to the (awesome) local shop, but will replace the neck if the neck needs replaced before paying for the setup.

What are your thoughts, wise ones?

Could someone post these for me? Cody emailed me these a while back but they got lost in the crash.
