JMI – Tone Bender MKII – OC75 vs OC81D Transistors!! – GAS Chann…

JMI - Tone Bender MKII - OC75 vs OC81D Transistors!! - GAS Chann...



This review shows the diferences between a JMI Tone Bender MKII with OC75 germanium transistors and a JMI Tone Bender MKII with OC81D Germanium transistors.

We can note that the OC75 sounds more Heavy and the OC81D sound more like a Fuzz Overdrive.

With the volume pot roled Off, the OC81D shows a clean and juice sound.The MKII with the OC75, in the same test, sounds more dirt and fuzzy.

Two lovely pedals!

    OC81 has a more pronounced low end. Its a bit muddier than the OD75, but a bit warmer. Both sound great.

    Nice comparison video – Love that wild OC75 sound! Those look like vintage OC75 transistors and new production DSI OC81D transistors – correct?

    Really suprised I thought I would prefer the oc75 but like the the oc81 better it didn't have that sharp ear piercing highs to my ears .

    I like the way the OC81D's clean up, But the OC75's on full volume sounded better in that rig. I like the OC81D's more on a les paul though.

    Dude, we may have different sounds and styles, but a lot of questions I had were answered. Thank you man for taking the time!

    Neither are real versions of the transistor. They use modern Chinese made oc81d’s that are much lower in HFE and leakage and sound like shit. The OC75’s are bought from Langrex in the UK and are also modern made versions. The codes stamps are wrong and the actual tone isn’t as good either but they sell 50 pcs for $500CND So people buy them up

    Both have knockoff transistors. So you’re paying for what? A really nice looking case.
    And aren’t these built by the same dudes that do British Pedal Company? A shady lot…

    Made with fake, Chinese OC81D.
    Very disreputable company all around. Likely affiliated with Music Go Round UK. Google search Music Go Round and "stolen guitars".

    If you're gonna pay this much coin for a TB, get a legit one from D*A*M or Pigdog or Analogman or LIC or Lumpy's etc, etc…

    JMI uses modern reproduction transistors. Likely Chinese. Look at that shitty pixelated printing on the OC75! For the same price you can buy a TB from a reputable seller using legitimate new old stock parts.
    JMI/British Pedal Company are shady as shit. Do a lil google search on em…

    You need a slightly overdriven amp to get a really good sound. In front of a clean amp it sounds "difficult".
