    I have a few pedals which don't have the greatest bypasses and I'm thinking of wiring a fulltone switch in. They are my MXR Phase 90, my Big Muff, an impending NY Bassballs and an impending Whammy pedal. I'm sure the wiring-wise the first 3 will all be fine, but I'm concerned that there might not be enough space in the casing for the 3PDT switch, particularly in the Phase 90 and Bassballs.

    Also, the Whammy is obviously a digital pedal so I'm a bit more wary of this - does the existing bypass cut of the A/D and D/A converters but still leave the signal running through a cheap buffer or is the digital circuitry always in the circuit?

    Any advice appreciated before I go in too deep.

    Sounds like a lot of work to modify each pedal. You might want to consider doing what I did, and get a true-bypass footswitch and stick the effects inside the loop. Plus, you will be ready to go every time you add any new effects.

    Check out www.loooper.com and www.pedalboards.com

    You may be right - once I add up the cost of all the replacement switches it costs the same as a separate box. So what are the options out there and is there anything to choose between them? (For me size is a very big factor, the secondary factor being durability of the main switch and ease of replacement). I assume they are all as 'true-bypass' as each other...

    The true bypass box will likely be your best bet. Sometimes it is not as simple as just replacing the switch. If the jacks are hard wired to the circuit board - as it the case with most mass produced effects - you will have to scratch out specific traces on the circuit board itself.

    it cost me £40 from a bloke who lives sw of London(forget where). You can find him under the username dotdotdot on http://www.harmonycentral.com (on the effects forum). I met him when I bought mine and he's a genuinely nice guy. He does variations and his site is http://www.monkeyfx.co.uk/routers.html if you want to take a butcher's.

    BTW the guy who makes looopers is based in the US. He does ship to the UK and is also on HC as DBoggs

    Take your pick

    There are a few previous threads on this topic. Try a search for bypass in the Effects forum. I use a Morgan Miller Bypass pedal with my pedal board. It allows you to bypass all the pedals and send your signal straight to the amp when you're not using effects. No tone suck from all that metal and circuitry.

    Unfortunately, I think Morgan Miller's site is down, so I don't know where else you might be able to find one.

    Here's some links to previous threads...

    He's based in NY and I've heard that it's best to check availability before you order as you will eait until he gets them in.

    Thanks CS! I was wondering what happened to MMFX.

    I bought the single loop pedal for $50. I don't see it at the site, but I'm sure you could special order it. It serves my needs, since I use effects very sparingly, and I'm content in having all 4 of my effect pedals in one bypass loop.
     
  11. Can somebody get me an schematics for a bypass box? Something with 3 loops and a tuner out or anything in these lines.:confused:


    thanks
     
  12. Something along those lines. . .
