    Hello

    I've got a US Telecaster with the Fishman AST Powerbridge and love that sound. (80% magnetic Neck PU and 20% Piezo)
    I own a Parker Fly from the 90s as well and that one even offers tone control with the Piezo Signal.
    That's the best you can get but a lot of / too much electronics necessary.

    Now I'm thinking of ordering an Archtop Guitar with built in Piezo.
    As far as I found out, Fishman seems to come closest to my aims.

    I want just 1 Jack (needs to work with mono & stereo cables)
    I need to blend both signals on-board in the same way as with my Tele mentioned above.
    I don't want external Mixers/Pedals...
    Internal Microphones are no option, since feedback problems come to fast already on lower volume.

    As far as I've seen, there are the necessary products on the market:

    1. Fishman Powerchip – Thomann UK
    2. Archtop Guitar Pickup | Fishman
    3. 3-way switch (magn./both/piezo)
    4. Built in Batterie Holder 9V
    5. 2x Volume Control (one for each / tone only for magnetic PU)

    In the end the most difficult thing might be to convince the Luthier to build it that way.

    I've read a lot on Archtops with Piezo, and this might be a good solution.

    But maybe you have a better idea?
    I would be very interested to hear.

    Thanx & Greez,
    Rainer

    The Fishman Piezo bridge pickup is so loud that you don‘t really need a preamp. I have it in combination with a Schaller floating pickup, but I‘ve never mixed the two.

    However, yesterday I stumbled upon this:

    NOLL MixPot 1 | Preamps, Tonmodule | Elektrik, Knopfe | Parts | Rockinger Guitars

    One pot to mix them all Archtop with additional, blendable Piezo (built in) & just 1 Jack

    I‘m seriously thinking of getting one to finally take advantage of both pickups on my archtops. Of course the question is always whether you can change the battery through the f-hole.

    Thanx docsteve!

    Looks good, but it needs 2 Jack Inputs.

    The Fishman Powerchip is not a preamp.
    It enables blending both pickup systems.

    Regarding the battery I guess I'd need something like THIS

    What has worked for me:

    - KA 12- adjustable pole piece floating humbucker
    - Barbera Soloist transducer



    You need a new bridge made to hold the Barbera Soloist transducer saddle. You also need a two channel amp, a two way speaker with a tweeter and a stereo cable from your guitar that plugs into each amp channel. I use an older AI Clarus 2R Series III head with an 8” Buscarino Chameleon Speaker and a Planet Waves stereo cable. I set the channel with the magnetic PU to be primary by volume and the piezo is set to a lower volume to provide ambience. I set the Chameleon to acoustic mode with the HF tweeter engaged. The sound is the magnetic sound with some added acoustic ambience from the Barbera. I have found more success controlling the transducer volume at the amp vs a pot on the guitar.

    You are right, I didn‘t read the description of the Fishman properly. But what makes you think the Rockinger needs two jack inputs - sure, it doesn‘t have a stereo jack, but two inputs?

    .........This thread makes me think even more about the new Fender Acoustasonics - particularly the Jazzmaster. I have to wonder how close to the op's mark these new JM's may be, and whether he may have tried one.

    I'm not knowledgeable enough to offer any help, sorry, but in any case good luck !

    There's your snag.

    A stereo plug has a hot tip, a second hot-spot on the barrel and a third ground contact on the barrel.
    A mono plug has a hot tip and a ground contact on the barrel. The place which would be the stereo hot-spot is instead grounded.

    What you're proposing would need one of two things:
    a) A manual switch that disables the stereo function and shoves that signal to the tip; or
    b) Some kind of sensor and digital switching system that would say, 'Aha! I sense ground at the stereo hot-spot so I am going to shove all signal to the mono tip!"

    Thanx to all of you for your input.

    This is what Fishman writes about the Powerchip Features:

    "Fishman-designed piezo volume control works in conjunction with an exclusive “Smart Switch” circuit, which automatically splits your piezo and magnetic outputs to stereo, or mixes them to mono."

    Sometimes I might get something wrong because of my limited english, but I hope not on this issue?

    I'm skeptical that you find either one (although I get surprised every day). It probably isn't too hard to wire in the manual switch yourself if you're handy.
    Hang on - I thought that stereo jacks had been around for ages doing exactly that. What did I miss?

    Don't know, how long it's on the market, but seems to be perfect for the task.

    The cheap way is to wire the guitar in stereo then for mono use a short cord you can loop on your strap with a stereo plug inserted that leads to a female plug end wired in mono for your standard cord. I have guitars and a cello wired this way and it works great. I also put in a blend pot instead of a 3 way magnetic/both/transducer switch that has the neat feature of changing the balance while keeping the volume level.

    Carrying a stereo cord is easy, I split it with a Y on the end to process the signals separately. With each instrument I decide which is the primary pickup and wire it to the tip part of the jack in case I ever get stuck with just a mono cord.

    Yamaha AEX 1500 had both a piezo and mini-humbucker. They show up used not infrequently.
