    Rangemaster maybe? LPB-1 came along in 1969.

    edit: I was thinking transistor instead of FET, but FETs were around back then so it's probably something from that era.

    Now way to know without a schematic. But I suspect it will be a Jack Orman creation, or variation thereof. Orman seems to have done more with transistor(an FET is a type of transistor) than just about anyone.

    Jack Orman...that's a good guess... but since it has Tripp's finger on it, I think there might be interesting twists to an existent circuit, at least.

    Now let me fix that video link:

    Was Orman involved in any commercial products back in the 70s?

    The preamp in the echoplex used a JFET and the internet tells me it started production in 1970. That's not an overdrive, but it is evidence that it was being used to amplify instrument audio back then.

    Word on TGP suggests that the FET Driver is inspired by the BK Butler Tube Driver.

    Drop a couple of JFETs in for the tube

    That's great and all, but we need an MXR FET Driver schem to
    compare it to.

    You seem to have your mind made up, so that's really sort of the end of the discussion for me. I'm not interested in convincing anyone of anything. For the rest of us, I'm still thinking Orman, or since it's Tripps, a design pulled from the Craig Anderton book again, as he did with the Red Llama\Tube Fuzz Sound.

    I'm merely speculating, just like you are. I really don't care what's in it. I thought Bonamassa sounded better in the video before he turned on the FET driver.

    I'm more interested in knowing what the first FET overdrive/booster was like the OP asked. Anyone know the first commercial FET OD?

    Similarity to a JK Butler Tube Driver (soundwise, dunno about the schematic) is my guess as well, since Joe Bonamassa's sound (and playing) has always been influenced primarily by Eric Johnson...

    Looks like FET version of Tube Driver. FET or Field-effect transistor is common solutions for pedals, which claims to mimic tube-like sound and close overall scheme. All that Amp-in-a-box pedals use FETs. Basically it's just a transistor type. Nothing "common" here. Just like OP overdrives. Hundreds of different pedals with different sound.

    Well, and a price is too much for mxr, IMO.

    I think MXR is definitely using the BK as their "inspiration" for the FET Driver.

    Sounds pretty good, but I'll wait for the probably-cheaper, hopefully-BK-color-schemed, non-signature version...

    I would love to get my hands on one. Anyone carrying them in the US yet? A quick google search only shows Andertons at 190 pounds :eek:

    The only one that has been released is the black JB model. Dunlop hasn't verified they will release a "non-sig" model, but I don't see why not. I'll wait.

    I'd love to have one likee that. Looks like it's a blue fuzz face mini next to the FD.

    I find these demo's don't really tell me much about the pedals tone other than it's smooth. could be a Blues Driver or any other 100 type of variation. how about loud/soft, on/off, roll the volume knob back on the guitar etc.

    It sounds great. Hoping to pick one up soon!

    Rumor has it they only made 500, and the ones allocated to JB's site are gone. Andertons was the only other place that got any, don't know if they have any left.

    Dunlop said they have "tentative" plans to release a non-sig version... imo there's no way the WON'T release one if the sigs sold out that fast. So alot of us, who didn't want to pay extra for JBs sig (and I love JB), or would rather have the "tube driver looking one" instead of the black one, are waiting.

    FWIW... I notice alot of common ground between the FET Driver and the new Wampler Velvet Fuzz. Wampler has said the VF isn't a straight-up fuzz, and has some JFETs in there as well, so...
