Another DuoCast

[caiofilipini]

Wrapped this one up last night. Built it for a close friend because I think he needs one, even though he doesn't know it yet.

I decided to leave off the charge pump and build it like the original. All the relevant caps are rated 35V or higher, so it could be run at higher voltages too.
Used a BC549C and a 2N404. Gørva S90 enclosure, aluminum knobs and LMS pro switches. Looks clean and sounds great!

Your friend is very lucky. Awesome build, super clean.

 

[Preverb]

Looks classy with those knobs.

I've never tried one of these in real life but I am kind of interested in the pedal more for the fuzz/OD. Would it make sense to build a Simulcast in that case? Also, I find some of the videos I've heard a bit harsh and notice many comments about relative lack of bass. Are there mods to add the bass back in?

That looks ace! I might have to give the Gorva enclosures a shot…

Thank you, folks!

I haven't looked into any mods, but there was a similar discussion recently in a different thread:

Is it just me or is the Simulcast kinda bright?

Just finished this pedal today. I like it! But I wish it had a treble roll-off tone pot. I spent an hour or two auditioning Ge transistors, and it seems to prefer slightly higher hfes. The highest gain tranny I had which worked was a Russian MP20 at around 90 and it sounds pretty good. Actually...

You're steadily putting out some incredible builds!

Yeah stop making us look bad!

LOL amazing!

 

[WheatAndBarley]

Were there any issues fitting this build into the s90 due to the transformer height?

 

[Chuck D. Bones]

Very nice build. I have a Simulcast in the queue.

Thanks, Chuck! Curious to hear your thoughts.

No issues, the S90 is deeper than a 1590BB.

Looks great!

I’m digging the yellow wire. Mine are usually color coded

That enclosure is beautiful... Wow

I'm a sucker for these Gørva enclosures.

With what did you replace the switch? What is that orange resistor in the switch location?

It's a 0Ω resistor, aka a jumper. Basically it's always in 9V mode.
