The GigRig GrumpyBot Buffer

Sometimes your signal just needs a little push, which is why we designed the GrumpyBot Buffer

This very clever design delivers a very clean, quiet, low impedance signal, and delivers a tone which is vibrant and natural without sounding harsh the way some buffers can. 

We also understand how valuable your pedalboard space is so we've made it ultra compact.


POWER - 9V-18V DC 
DIMENSIONS - 7cm x 4cm x 3.5 cm
WEIGHT - 65g

    Not all buffers are alike. This one is perfect. No sound colouration; just keeps things bright and perky the way they were when they left your guitar jack.

    Grumpybot buffer

    Size: very small and compact.
    Material: very hard metallic box, plastic in/outputs but very sturdy.
    Look: looks really cool with the shiny angry eyes!!
    Sound : sounds really great. Very transparent, just gives you back those highs lost with multiple cables, and doesnt effect your sound in any negative way. There is no noise added to your sound either.
    Cons: It would be cool to see a version with ins and outs so you could use it and the biggining and end of your chain.
    Overall : a really great investment for and guitar player going through multiple cables.

    What a difference...

    Never knew something so small, in a lovely little case, and so unassuming, could do something so dramatic! One of the better investments you could make. Thanks.

    Nice quality and construction and I liked the 'boutique' packaging. Good, quick service with a status email whenever a handler had a wee or sneezed.

    I bought this for a different reason, but tried A/B-ing a PBass->Amp with PBass->GrumpyBot->Amp.

    To my ears, with the buffer sounds significantly better. It seems to round-off & warm-up an otherwise standard/nasal/clanky tone: I assume there is some colouration from the internals, but like to think the GrumpyBot is decoupling things for the instrument's real tone to come through.

    Still a little bit disgruntled with the price for something so simple, but won't bass without it now.
