GK rails in a pedal?

[boomertech]

The reason why there are two versions for the boost circuit, is because we were trying to see if the boost was a major part of the "rails" tone. Version 1 of the boost can be completely bypassed, where version 2 of the boost is how the original 800RB is using the circuit. In the original 800RB, the boost is always 'in-circuit' and just switches between a set level to the adjustable level.

Hey Frank and John, thank you guys for this amazing thread and pedal!

Just a quick question, is the pedal inverting the input polarity? I'm a little lost in the signal path I'm asking because If the sound guy ever wants anything Pre Fx and blend it with post FX signal, I'd better have a non inverting pedal.

Thanks!

BUmP!

Was the polarity question above ever addressed in PM or elsewhere?

There are a couple of answers depending on version of boost circuit used:

With version 1 of the boost circuit.
Boost circuit deactivated = non-inverted output
Boost circuit activated = inverted output

With version 2 of the boost circuit.
Boost circuit active or deactivated = inverted output

I just get to this topic today...very late, here is 2:40 am and can't stop reading the 48 pages...great sound!!
Is John still making it? I really want one

 

[johnk_10]

I'm making just one more of them.

 

[El Spearo]

Oh no! Is there anyone else making them?

Edit: I just remembered Boomertech was also making them. Is he still?

AFAIK boomertech never made them.

Oops, sorry. I'll shut up now

what's that about inverted output? IDK much about that...

I'm currently not using Dom pedal.

I picked it up mainly for headphone based rehearsals and currently I'm not rehearsing like that at this time if anyone is interested.

@domdec314 built mine. Don't know if he still makes them.

It's been a little while, but I'm open to building more if people are interested.

I'm like reviving a death posting here, but in jan I asked for John_K to make one pedal and sold to me...It arrived to Chile just yesterday after a month but, have to say....IT'S FREAKING GREAT!
What a wonderful tone it has

what where/are you charging for them?

feel free to PM

I'm still building these. PM coming your way...

I'm interested in trading for one of the Johnk built pedals. (Purely aesthetic reasons.) I have some things in the classifieds right now, but I'm mainly thinking the Blue Tube.(comparable price.) Thanks for anyone considering.

For Sale - 2x tube preamp:Alembic F2B & B.K. Butler Blue Tube II
For Sale - Boss BF-2 Flanger & DOD 525-A Compressor/Limiter

Played this with the kalaloch today. Wow . What a revelation. I regret selling some pedals prior to testing with the verellen.

Nice work guys!!!!

I keep feeling like I should buy one of these pedals but I just don't know what I'd use it for. I have 2 800rbs in my live rack, I rehearse with a 400rb and I have a spare 800rb. Btw, I have always read that 400s aren't very loud. Well, I have an '83, play into a 2x15 with EVs, I crank the master and barely open the vol knob it it is loud as hell in my metal/hard rock band with a very hard hitting drummer.
