Request: Digital Reverb version 2

Note: This one is experimental.

Accutronics updated their Belton Digital Reverb unit (BTDR-2) and made it much smaller. It also has a different pinout from the old version. I was asked to update my old layout, but I thought I’d try something a little bit more exciting while I was at it.

I put together a pretty straight forward schematic based on the version 2 datasheet circuit with the same embellishments as in version 1 (from the D-Verb schematic from GGG). But having two outputs it became apparent that true-bypass wiring would be hard without employing either a 4PDT or some additional switching circuitry. Therefore I decided to put this together as a buffered effect, and the general ideas here were borrowed from Merlin B’s “Small Time” delay. So the intention is for this to be a buffered reverb effect with mono/stereo output and tails.

It looks good on paper, but I realize there’s much for me to learn still. But rather than leaving this on my shelf for a month or two while I source parts and give the build a try I figured I’d put it up here for the brave ones among you to have a dig at right away.

I’m fairly confident the vero layout follows the schematic at least.

Feedback appreciated if you give this one a try, as always :)

Update (18.05.2012): I built this one myself the other day and it worked beautifully. Verified :)

Request: ROG Condor cab simulator

Here’s a vero layout for the Condor speaker cabinet simulator from www.runoffgroove.com. Looks very interesting.

Update (14.05.2012): Now verified, thanks to Mark L.

Engineer’s Thumb

Another compressor, this one by Merlin/ValveWizard. I chose to incorporate all the suggested mods on this layout. Let me know if you beat me to it building this one.

Request: Shin Ei Companion Fuzz

I have no idea what this one sounds like, but it’s probably fun. Based on the schematic over at GGG. As always, let me know if the layout works.

Update (11.05.2012): Now verified, thanks to Koen :)

Escobedo’s Jawari

For no particular reason I just thought this one seemed interesting. Supposedly it emulates the sound of a sitar. Though I’m not expecting anything profound it’ll be fun to try it out.

I’m hoping the transformer will fit (looks like the same size as the one for the Octavia).

Request: Catalinbread RAH

I’ve had a lot of requests for this one lately, and it was just traced out over at FSB so here’s a vero layout for it. I have no idea what this sounds like, but based on the hype it’s pretty good.

Update (30.04.2012): Layout now verified as working. Thank you Derek!

Site update: Vero layouts page restructure

You might have noticed already. The vero layouts page was getting a bit large for my liking so I decided to break it into several smaller pages based on the effect categories. Let’s see how this works, and if it doesn’t I’ll bring the old one back.

Request: Small Time

Here’s a vero layout for the Small Time, a buffered PT2399 delay with tails that should fit in a 1590B without much trouble. Do note the non-standard stomp switch arrangement (this one requires only an SPDT).

Tubetype distortion circuit

Found a small article on AMZ about some patented tube emulation circuit used in Crate amps. Jack Orman put together a simple effect schematic based on the patent information and I’m keen to find out what it sounds like.

The effect calls for +18v to work properly so I put in a standard voltage doubler. I’m curious about this one so I’m definitely going to build it (eventually), but let me know what you think if you decide to build it too.

Request: Himmelstrutz Fetto

Here’s a vero layout for the Himmelstrutz Fetto. I also did a stripped down version with all switches and jumpers hardwired in the default setting. Both of the layouts are based on information from this thread over at freestompboxes.

Note that the correct transistor has yet to be determined, but it’s a JFET with D G S pinout. I’ll update the layout if/when the identity of the JFET is discovered.

Update (03.05.2011): Built the “full” vero yesterday, and although I was unable to find the correct transistors it did sound good using either 2SK117 or 2SK170, so I guess the vero itself is now verified.

Update (03.09.2011): I’ve successfully built this and I’m calling it verified. The only uncertainty is the exact transistors used in the original unit, but in my experience 2SK170s work just fine.

Update (10.12.2011): The stripped-down version is now also verified thanks to adamk. I also updated the layouts with the reputedly correct transistor (2SK170GR).

Update (28.12.2011): There have also been reports of the 2SK170BL sounding better than the supposedly correct 2SK170GR, so you might want to try both and make up your own mind.

Update (19.04.2012): Boxed the stripped version as a 2-in-1 with the King of Tone single version. The Fetto part is on the right side.
