Good buffer to place at the beginning of pedalboard
- Roast7
- Breadboard Brother
I would put a good buffer to the beginning of the sequence of pedals
I thought the "Amz JFET transistor BUFFER" but wanted to build on stripboard.
've Looked schemes stripboard but found none so with good feedback ...
What do you advise??
best regards
Daniel

I'm using a Klon buffer, built from a kit that this guy sells: http://shop.pedalparts.co.uk/Klown_Buff ... 46591.aspx
I had a Boss tuner at the start of my chain but swapped it for a TC Polytune Mini which is true bypass....the buffer works well, actually colours the sound a little bit but in a nice way.

I just use the black toast buffer at the start of my board.

Because I wanted was the most appropriate to start the chain of pedals.
opamp vs jfet
opamp version is capable of giving lower output impedance (Z) and unity gain (gain = 1), Whereas the jfet's output impedance will be higher and slightly less than unity
which to choose? many people advises the jfet.

Gain is fairly irrelevant unless it's a massive drop because it will always be on.

This is one of the JFET buffers shown on the AMZ site, the one with the 1/2 supply voltage divider:

I haven't experimented with different types for quite a while, but if transparency is most important to you I'd probably recommend a generic opamp buffer. I thought the JFET buffers did colour the sound more.

I did what you are doing with this layout (not vero sorry, but shouldn't be hard for you to make one?)

Very funny
Well someone was making Veroboard jfet scheme, this pcb here:

Or even Veroboard this PCB

I do not understand, but nobody uses buffers at the beginning of the chain of pedals??

Plenty do, in one way or another. I have onboard buffers in my guitars (JFET, like the one above). If you want to explore the kind of differences people think they hear just build a bunch of options (BJT, JFET, op amp) and compare them. It's $2 in parts.Roast7 wrote:I do not understand, but nobody uses buffers at the beginning of the chain of pedals??
If you're interested in best performance and not "color", whatever that means, build an op amp buffer with the biggest supply voltage you can muster (e.g. ±15 V, though 9 V is probably plenty for usual pickups).

never built the AMZ.. the pure sound of the black toast was good so I just used itRoast7 wrote:This baja is like Amz?rocklander wrote:I did what you are doing with this layout (not vero sorry, but shouldn't be hard for you to make one?)

yes.. many, as did I .. as posted in that link.Roast7 wrote: I do not understand, but nobody uses buffers at the beginning of the chain of pedals??

Personally I would employ a tube buffer like this, but running with less high voltage:Roast7 wrote:Because I wanted was the most appropriate to start the chain of pedals.

which to choose? many people advises the jfet.
I think this diagram is similar to VHT/Fryette valvulator or Coopersonic tube cleaner.

Why? That has absolutely none of the advantages of a 50 cent modern buffer.

12v tubes are still possible to buy. 12U7 (dual triode) seems to be perfect candidate to become a base for battery powered friendly tube buffer

I wanted something simple just to maintain the equal sign and good and transparent because the pedals are all in True Bypass.
That's why I thought the AMZ, because they say it all.
but I wanted to build myself and preferably in Veroboard.
Maybe I'll do it, like build a IvIark put here (jfet), and another with opamp, then choose.
Advice for other projects in stripboard, in addition to the layout IvIark posted???
