There are companies that make these with different numbers of switches/loops. Road Rage and Loop Master are two of them.

They get the job done and provide true bypass routing to your effects.

However, they use those big old clunky 3PDT foot switches.

There are companies that make relay TBP switchers, but they are all programmable, and expensive. I'm looking for one that is non-programmable and simple and hopefully cheaper.

Through some internet cruising/prowling/lurking I came across the (attached link) circuit boards that seem to do what I need. Put as many boards as you need in a box. Add non-latching SPDT momentary switches and LEDs and your next stop is superstardom.

Does anyone know of an already made box like this?
Has anyone used these boards before?

Note: The attached link is for their obsolete version. I used it because I think it gives a little bit better picture of what is going on. The current version is also on their site.

Thanks in advance.

Since posting this a few hours ago I continued my creative searching. There are a few companies that make them.

Loopswitchers (dot) com:
They build both the mechanical 3PDT version as well as a silent relay switched version. Since they are already built, they are more expensive.

Mammothelectronics (dot) com:
They offer KITS for both the mechanical 3PDT type AND the silent relay switched type. Since they are kits, they are cheaper.
A 5 loop relay switched kit is $105. This might be the hot ticket.
Added: Mammoth also offers a package of the SPDT silent footswitch and the relay board separately.
You can add this feature to individual effects pedals (there are how to videos on Youtube).
Or you can build your own silent TBP switcher.
However, comparing the prices for the switch/board module versus a complete 5 loop box kit, the 5 loop kit seems to be an extremely good deal.

These two companies are the only ones that I've found that offer the electronic relay switching option.......so far, anyway.

There doesn't appear to be much interest here, but I thought that I'd up date it with a few findings anyway.

One Control
I think that they are a foreign/overseas company.
They make programmable as well as traditional 3PDT manual true bypass switchers / loopers.
I am assuming that the programmable ones have silent switches with internal relays.
As for the manual 3PDT type, I recently bought one off of a local CL for super dirt cheap.
They list and street price for way more than I paid, so I had to jump and see what its story is.
There is essentially no hand wiring inside.
All of the switches/jacks/LEDs are mounted on a PC board.
It should be plenty rugged, but if you need to replace something it could be a major project.
As for modifying it, forget about it.

Walrus Audio
They make programmable as well as traditional 3PDT manual true bypass switchers / loopers.
I am assuming that the programmable ones have silent switches with internal relays.

They make a programmable silent relay switcher.
It is a kit.

Interesting looper and the price isn't bad considering all the options.

However I couldn't find where the plastic end cables were at.

RicOkc: Which looper?
Which company?
And what "plastic end cables"?

Maybe you should re-read your own post.

What you called a "Relay board".

They've been referenced to as "Loopers" for years.

RicOkc: There were several items/assemblies/etc in my posts that could be referred to as "loopers".
Or switchers.
Or whatever.

Your reply calling out the link for the board cleared up which device you specifically were talking about.

I'm still not clear as to what you are talking about when you refer to "plastic end cables". Maybe it's there somewhere and I flew right by it.

More general info that I've gathered regarding the individual board assemblies.....

Regarding that TBP relay board/switch module/looper/whatever:
From what I can decipher out of the AMZ Muzique site:
- The bare boards are no longer offered.
- You can buy a board and just the microrocessor.
- You can buy the board and all components on it. (For the price, I don't know why you'd want to do any of the previous two.)
- You can buy the board and components and the external switch. (My guess is that this is what most people do.)

You can also buy a board/parts/switch kit from Mammoth Electronics.
From what I can tell, it is NOT the exact same thing as the AMZ kit. (At least I would assume that it is not.)
The Mammoth kit is a design from a gentleman named Jack DeVille.
And as of this date (April 2018) Mammoth is out of stock.
I'll probably buy one when they get some and see how it works.
By the way, Mammoth has been very good about responding.

One concern that I have with either of these designs is the microprocessor.
Specifically long term support.
If a module goes bad, they are cheap enough to replace the whole thing, and unless you have the equipment are probably not worth troubleshooting anyway.
But how long will it be before the actual part is no longer made? The way that technology moves these days, it could be next week.

What I was expecting to find when I started researching this was basically the switching circuit from a Boss/TS type pedal, but instead of turning FET switches on/off, it drives a relay. All garden variety parts. Maybe there is one out there somewhere.

The good news: There is another switch module/board/looper kit/whatever out there.
It is called a Monomonster. There is a lot of information out there, including a couple of YT demos and a manual.

The bad news: It is on the Small Bear site. However, it is out of stock with no ETA. I get the feeling that it will no longer be carried by them. It is available from Banzai Music.......in Germany.

I turned over another rock today and another source crawled out.

Monte Allums has a TBP relay kit that appears to be the same thing.
He advertises it as mainly being to retrofit existing pedals, but AFAIK it should also work in a pedal board application.
The down side is that it does not come with a switch, which will add another $4 or so to the experiment.

Updated 29 June 2019.......

I have no affiliation with this company whatsoever, I'm just passing along a deal that I found.

Mammoth Electronics has a deal with a capital "D".

You can buy a "Lace Looper" kit for a 5 way true bypass looper/switcher box that uses relays and clickless switches instead of the traditional 3PDT switches for $88.
All parts including the box, jacks, switches, LEDs and relay boards are included.
The box is unpainted if that bothers you. You can get one painted for extra, or do it yourself.
They also offer 3 way and 4 way versions, in 3PDT and relay silent switch types.

The downside: They are behind on their assembly of the relay modules/boards. However, I was told that they will sell the boards unassembled if you want to do it yourself. The picture of the board shows the components as being DIP/axial/traditional type leads, and not the modern tiny SMT surface mount types.

There is a programmable IC (PIC) on the boards that should come programmed. User to verify before ordering.

As of today their web site still shows this offer. I'd call them first to verify before placing an order. The person that I spoke to is Matt.
