This is so wierd. Why does it still has a pair of horse legs? In my mind reversed centaur would be a man with a horse head

Love it anyway:D

Have you mesured the resistance of your work-alikes before putting them in? Makes a huge difference what resistance it has with light and in the dark. I know they are not cheap but maybe you can find a diy photocopler/led+ldr that works better

Like Marty said, pics would be nice

You could contact alpha and ask them if they would do a small run. On their website the biggest value for 9mm pots is 1M.

Maybe it is easier to just design it to wire off board

Thanks for the Schem. I think I'll try to jam a Chasm Reverb in a 1590a, at least in the long run...a lot on my workbench right now

Huh, I honestly thought the Bricks were epoxy potted (aka Gooped). Interesting.

I thought so too.
Hmmm maybe it would be worth it to trace one and include diy belton bricks on self designed boards like super small 1590A reverbs etc.

Hallo guys and gals,

I started posting here and just now discovered this section. So I think I have some introduction to do...

I'm from Germany and started building pedals about 12 years ago but stopped the same year. I build a few amps over the years and recently I had to switch to Pedals since Amp building is just to damn expensive (for a Student). I'm studying electrical engeneering but hope to graduate next month.

I'm a lousy guitar player, but apparently I have a thing for diy I'm super into Overdrives and Distortion sounds but as I was building pedals in the past my big goal was to build all the Lovetones but back in the day there were no schems and boards available. Apparently that changed over the last years (thanks Alan and LaceSensor, you helped me a lot over the past few weeks and prepare for a few questions when it comes to actuall building those bad boys ). Also I'm a bit of a uC fan, working on a few Midi projects but proceed reaaaaaly slow there since I have no time for it.

Well that's me. This community is great and I hope one day I'll be able to give something back.

Regards Andreas

I'm so jealous
Great builds...all of em are on my "have-to-build" list

Also in for a Dino board when it's available.

+1 for me please

Good stuff!

What does the Russian writing say?

Siberian Bear 

Google Translate did a good job, so did you. Very clean build, it's been a while since I've seen a build with a battary clip

Insane 1590a skills! Top shelf!

Does it come in an iPhone version? 

Sure but it costs twice as much, has two knobs less and it comes cast in epoxy because screw customization

How does it sound?

It's awesome. I never played the VH4 so I cannot compare. The controls are super powerful.
It sounds super tight. You can easily dial in sounds like the modern Metallica or Tool. With that much bottom end I ended up with a great sludgy tone, not muddy. Takes low Tunings really well, I tried Drop B. Actually it handels low tunings better than the Drive channel of my amp(it is dual rec based)
I'm happy with it and it will get a box and a place on my pedalboard as soon as possible.

Hallo guys and gals,

Just wanted to share this prototype build. Since I've been offering these PCBs I just wanted to get it verified by myself so I build it with the stuff I had at hand.
The OP amp supposed to be an OPA2134 but those are kind of rare in local electronics stores so I subd it with a TL072. The zener Diodes are also different types but mine are also 5,6v zener so they should be close enough.
I had no 1590bb at hand so I took the only sturdy box I had at hand that was big enough. It's the box the first Samsung Galaxy Phone came in so once it gets a proper box I'll give it the name "GALAXY Drive".
Also the wires are really sloppy, i wanted to finish it up quick so I could test it before my sons bed time

For the prototype I did not mount a jack for the output that goes straight into the Poweramp but I'll do it on the real build.

The sound is superb. I had it in front of my Madamp, into a fender style channel and is just so brutal. It's tight and has a solid bottom end (a bit too much for my taste but I can dile it down to a level where i like it). I was afraid that it would be a bit too close to the BE OD but it is not. I'm looking forward to put that baby in front of my SLO Clone and cranck it.




Ps: I used greenies for the caps but since I won't have pots underneath the pcb I mounted them on the other side, with the switch on board there is a lot of unused space underneath and I wanted to avoid having problems with the lid in a real 1590bb

Sorry for double post but here are some gut shots

Apparently all the pics I make with my mobile are to big for this forum so just a link to my Dropbox instead
