NICE! I just sent them my set of Guild LB-1 humbuckers to rewind/upgrade.

Yes, that one. Please take no offense, I'm well aware that PPCB, Aion and Madbean all offer SD9 clone boards. My question is just about an official schematic not being available, seemingly anywhere.

Seems like there is a schem available for almost everything Ibanez, and it makes sense that there aren't ones for some of the rarer pedals. But the Sonic Distortion is pretty widely available (maybe not as affordable as they once were, but still). I've seen Dirk Hendrik's schematic, and...

Sorry, have to ask and the search I ran on the forums were specific to particular builds. My query is more general: as most of my pedals are DIY and true-bypass, I'd like to incorporate buffers in some, if not half, of them (maybe alternating buffered-->true BP --> buffered, etc). What is a...

Nice! I built the Brown Betty config, and keep going back/forth on which one I like better: that, or the Complex OD (Smallbox OD). I made an adapter board to use two BAV99 transistors as diodes, just like the Friedmans. The Brown Betty is just classic rock in a box.

Here's the schematic: I basically removed/jumpered Q6 and Q7 in my layout, and omitted the related switching section connected to those in the above schematic. I left the cap values the same, except for C9, which I have plugged in lower values; the DS-1A (post-1994) has .068uF in that...

AWESOME find! Thanks! I've rev-engineered several from these over the years using the service manual PCB layouts - most recently the MIJ Boss DS-1. FYI - the DS-1A service manual has a cleaner version of the MIJ DS-1 schematic, as well as the original MIJ layout. Another FYI - if you're able to...

I recently got my prototype DIY build of a MIJ DS-1 going, and noticed two things: 1) It is a LOT thicker than any post-1994 DS-1 I've owned. So much so that I'm looking at reducing one of the coupling caps to make it a bit leaner. I mean, dialed in right, it's competing with a Metal Zone (in a...

There were some Easyvibe users a while back that noted the difference in sound between different LED colors, with green sounding especially good. Good idea (building it stock first). Report back with your opinions on the LED vs lamp. I'm building my ElectroVibe with a lamp as well.

Long story short: I had the urge a year or so ago to build a MIJ DS-1 from scratch. I traced the layout from the 1978 version, omitting the switching section; it's considerably smaller than the original. I sourced some TA7136APs from Retroamplis, but either those are bad or there is an issue...

This one has intrigued me for years. It was a 'boutique' high-dollar distortion in the mid-late 90's, back when there weren't nearly as many private builders as there are now. Just curious if it's worth building, what with other Marshall-esque drives out there (the Friedman pedals, Marvel Drive...

Thanks @Chuck D. Bones With work & the holidays in full swing until the EOY, I'll likely start back building in January. I bought a few from Aion and PPCB during the Black Friday sales, but these are all 'new builds' and will go to the back of the line until other stuff is done. :cool:

Thx guys - I'm probably going to shelve this idea for a while. If I get really antsy, I'll just do a 125B.

Crazy as it sounds, I'd love to build an Expandora clone but only in a ROUND enclosure. That's such a signature look, that I'd like to recreate it, if possible. I know Hammond doesn't make one - just putting some feelers out there to see if anyone else might have a lead.

I have an Aion Heliodor incoming, and I've made note of some of @Chuck D. Bones mods from other posts. I saw this one: "If you want to reduce the muddiness caused by too much bass going into the distortion stages, then try reducing C33 instead. Do it in small steps because C33 has a lot of...

I voted Strymon BigSky (I'm on my 2nd one now), but would whole-heartedly recommend the Source Audio Ventris and/or Strymon BlueSky V2. The Ventris has probably the best spring reverb algo on the market (True Spring).

Another one (again, not yet verified) is the 'Hot' mode from the Ibanez TS7, switchable by a toggle. It consists of: Adding a cap in parallel (don't recall where in the circuit) to reduce the value of said cap (assuming it's a bass cut) Replacing a cap & resistor in series with another cap &...

I've got an etchable PCB layout for an SD-1 that I created using the 1981 MIJ version's service notes. I removed the switching section, and made it very compact: it's less than 2"W, and a little over 2"L. It's not validated yet, though. :)

Same here
