Mercury / Vario Boost
« on: August 09, 2018, 02:45:41 AM »
Mercury, compares to Catalinbread Vario Boost.
Built on Pedalpcb.com board, 1776 fx relay bypass, acrylicfaceplate over laser decal.
Excellent sounds out of this one, very useful and flexible boost circuit. Love it!









Brett Kingman can demo it much better than I can:

You're building a pedal a day, an amazing amp and whatnot, all of it of professional quality. Do you find time to sleep?

Interesting, don't think I've seen this kind of "tune-able" boost before. Nicely executed -- the screwed in clear panel on top is becoming a signature mark!

I wonder why they used two TL072s, rather than one TL074...

So clean - keep em coming! I gotta check out this video, I'm also intrigued by the idea of a "tuneable" boost circuit.

Haha... no I'm not losing any sleep over this... and my bedtime has become way earlier than what it used to be. Nothing like a good few Zzzzzzzzzzzzzzzzzz....

Thanks Mrclean you must know about clean then...

Yes it's a great very flexible circuit, hard to understand why Catalinbread discontinued it. Probably just to change the line up and keep it fresh, maybe peeps didn't get the pedal? I think it's great.
Not sure about the two 072s versus 074... ask BuGG, he designed the pcb. I dunno what Catalinbread used originally.

Maybe it's my style of playing, but I think boosts are largely underrated/under-noticed. I'm sure there are a lot of TGP folks/etc who love boosts and have 4 different kinds on their boards, but 99% of my conversations, especially with local/younger players, regarding boosts all I get is crickets. Oh well. I was unfamiliar with this guy, need to do some homework.
