Also, John what did you do to get more gain and output from the preamp?

i lowered the input resistors to 22K's , lowered the 470K's to 100K's and added a clean JFET 10db booster to the output.

Here's yesterday's project. A little tube boost/OD. It's like a Valvecaster but I omitted the tone control and I'm running an NOS GE 12AT7 right now. Sounds awesome with the 5e3 build!

this is sick Travis!
great work!

[MAO]

Very cool Travis!

What is the power supply and curious, why the use of isolated jacks?

[Travis]

Thanks guys!

I kept it simple with this and shared the power supply for the heater and plates. That means the max voltage is ~12VDC

So far I've just been testing it with a onespot (about 9.6V)

Obviously with the low plate voltage you're not getting ideal performance from the tube, but the reduced headroom actually gives you a really nice overdrive sound.

It's not crazy loud like a SHO, it's not crazy saturated like a cranked Marshall, it's just some volume boost and some light breakup. It really sounds nice at what it does

Regarding the insulated jacks. I bought a couple hundred of them, so I use them a lot.

Travis, it's amazing, never see such a beauties. MAO I like you's also, like a lot the decal style especially your power logo.

This is a fun project, I wanted a pedalboard pedal. It's all made with guitarPCB boards, If I count the 3PDT wiring board there is 33 PCB. The boxes are 3 1590DD with 3 top A enclosures. To avoid tap dancing I made some loops with the fx in and the loop 3 is a simple fx send/return in case if I want to add something.

trom72, that is crazy cool!

Do the room lights dim when you power that baby up?

I'm actually working on something similar, not nearly as elaborate, more of a 3 way series/parallel switching system intended for modulation pedals in the middle of an effects chain, but you have given me a couple more ideas to think about. Thank you!

So how did you attach the enclosures?

And what effects did you go with?

 

[trom72]

The fx are :

LOOP 1 : Big muff with a LPB1 at the input and tone bypass switch, blues buster (marshall overdrive like), colorsound booster and delay

LOOP 2 : phaser and tubescreamer plus an order switch to reverse the order

LOOP 3 : fx send/return

LOOP 4 : compressor/chorus/delay

and after in series : tremolo/EQ/clean boost

The A box are just screw by using their srew holes(just need a good drilling). To attach the 1590, its 1/8 inch IPS nipples and nuts. hardware from lamps.

Thanks Trom, that is an AWESOME build! Very nice work and some cool ideas shown

That must have been a very expensive build!

[trom72]

Thank you, you're wright it's an expensive build, but it's almost a full pedalboard. It's a bit less than 400$. It's a bit less expensive that building them one by one.
And that's a fun challenge to make everything works.

Don't have an xlr cable right now but I'll be picking one up this week and give her a try!

Dead astronaut Tremshifter

[mug]

Cool - tremshifter is a great circuit! And a funny coincidence: I recently finished one, too



The second stomp is the modulation switch, I figured it would be useful



I messed up the enclosure by misplacing the hole for the power plug as visible above the pots - still thinking about how to close it (and no, I don't think this qualifies for the "Anti..." thread )

[mug]

@Sensei Tim: Looks really cool, I'm looking forward to hear haow it works!
But I'm confused - should'nt be there 3 audio plugs (line in, from speaker, to speaker) and one XLR?

[Sensei Tim]

Yeah but I wasn't planning on ever using it with a speaker level signal so I left it off

Fantastic build, it's very nice.

[bogey]

I've got to agree there's been some really classy builds on here lately.

I've not built anything for a while but this is my Fairfield Circuitry "Barbershop"



It was also my first  dabble  with SMD parts,



I wasn't too keen on the enclosure finish at first but it's kind of grown on me.

And it sounds FANTASTIC
